  • Calendar booking issue - Exchange 2003 and 2010

    - by NaOH
    In our organization we are running Exchange 2003 and 2010 simultaneously, with the hopes of migrating everyone to Exchange 2010 sometime within the next few months. Everyone is using Outlook 2010. Recently, we had an issue with transaction log storage on the Exchange 2003 server. This was resolved, but for some reason no meeting rooms on the Exchange 2003 server will automatically book meetings any longer. I have played around with this for a while, changing calendar permissions, turning resource scheduling off and back on, etc. No dice. My next step was to try migrating a resource to the Exchange 2010 server. After doing so, and setting it up as a Room, enabling Auto-Accept and removing the EnableDirectBooking registry entry on my PC, I can book a meeting with this room. If EnableDirectBooking is enabled, I get an error message stating: "Meeting Room" declined your meeting because it is recurring. You must book each meeting separately with this resource. This is despite the fact that the meeting I'm attempting to create has no recurrence. Now, I have also created a new test Room from scratch on the Exchange 2010 server, and I can book a meeting with this Room regardless of whether or not I have the EnableDirectBooking reg entry in place. All users here have this registry entry, and I'd rather not have to figure out how to push something out to remove it from every PC. Rather, I'd like to figure out what's different between the configurations of these two meeting rooms so that I could book a meeting room regardless of whether EnableDirectBooking is enabled or not. Any ideas, anyone? Thanks!

  • NFS confusion - writing many small files

    - by Antonis Christofides
    I have a Debian squeeze amd64 which is at the same time a NFS4 server and client (it mounts itself through NFS4). The local directory that leads directly to disk is /nfs4exports/mydir, whereas /nfs4mounts/mydir is the same thing mounted through NFS, using the machine's external IP address. Here is the line from fstab: 176.9.116.102:/mydir /nfs4mounts/mydir nfs4 soft 0 0 I have an application that writes many small files. If I write directly to /nfs4exports/mydir, it writes thousands of files per second; but if I write to /nfs4mounts/mydir, it writes 4 files per second or so. I can greatly increase speed if I add async to /etc/exports. (Writing a single large file to the NFS directory goes at more than 100 MB/s.) I am confused by the description of async in NFS. If my application accesses the local directory, system calls like write and close return even if caches have not been flushed to permanent storage. Apparently this is not true with NFS sync behaviour. However, with NFS async behaviour, even calls like fsync are ignored. Isn't it possible to work like local files, i.e. generally work asynchronously, but honour fsync and O_SYNC?

  • Virus cleanup + dying drive = XP Automatic Updates crashing in esent.dll

    - by quack quixote
    Background I'm doing system recovery on an old WinXP SP1 system brought to me on suspicion of virus infection. After taking preliminary backups, I used MalwareBytes to detect and clean the infection. I might've even gotten it all. In the process, I've discovered (a) the system drive is showing signs of impending failure, and (b) the owner has been using the system's old crusty IE-6 instead of the up-to-date Firefox I've provided for him. So naturally, thinking I had a relatively stable system, I tried to hit the Windows Update site to install IE-8, in case further training doesn't stick. The update site told me it needed to update the installer, and I started that process. Soon after, wuauclt.exe started crashing, reporting addresses in module esent.dll. There's a Microsoft KB (910437) on a problem with that DLL, so I downloaded the hotfix and installed. The crashing did not stop. I attempted to install SP3 from the offline installer, but that didn't fix the issue either. The system is reporting a few hard drive / IDE controller errors, but they don't correlate to the crashes, so they aren't the direct cause. I've also attempted to rollback to the time between the infection removal and the first crashes, but that doesn't help. Question The hotfix I tried to install dealt with problem in transaction logs of the Extensible Storage Engine (ESE) database. I suspect this issue is similar, but that the database itself (whatever the ESE database is) is corrupted. Is there a way to clean or clear this database so that system operation returns to normal? Can someone enlighten me as to what the ESE database actually is, and where it resides? Can I just locate some files and delete them to bring this under control?

  • Need advise for choosing software\hardware for virtualization.

    - by Anatoly
    Currently we have these servers : Windows SBS 2003 premium on IBM X266 double Xeon F43, 2GB ram. DC, exchange (70 users), Mssql. Windows 2003 R2 32bit on IBM x3400 with double XEON E5310 and 4GB ram. Terminal server (40+ users), ERP application based on uniPaaS platform from Magicsoftware, and Pervasive sql. Ubuntu 8.04 (simple pc box) with squid proxy, GLPI system and PHPBB3 forum for internal use. Recently number of concurrent users on Terminal server passed 40 users in rush hours and it gets stuck frequently. Therefore we need an upgrade. I think about transfer all physical servers to virtual servers based on cluster of 2 physical servers for reducing downtime. I think we will grow till 50-60 concurrent terminal users in rush hours. I also plan to virtualize 10-15 Win XP/7 workstation (office,ERP etc), and there is a little probability for Asterisk\Hylafax for 100 users (if it possible on same VM). Also we need NAS storage for 2-3TB. What hardware upgrade/purchase we need for complete this task? Which VM solution is preferable VmWare or Hyper-V? What backup software should we choose? Acronis or something another? Thank you in advance.

  • Network speed between a VM and another machine which is not residing on the same host, is 11MB/s at most

    - by Henno
    Problem Network speed between a VM and another machine which is not residing on the same host, is 11MB/s at most. Topology Facts ESXi5 version is 5.0.0.504890 VM has the latest Vmware Tools installed VM is using E1000 network driver Physical box has Win Srv 2008 R2 as the OS CrystalDiskMark says the drive on physical box can read/write 100MB/s vCenter is another vm on esx both vm and physical box are showing 1Gbps link speed Configuration Networking shows vmnic0 as 1000 Full NTttcp is a client/server tool from Microsoft for measuring pure network throughput Here's what I've done so far: Test1: VM is running Filezilla FTP Server (default settings, one user account made) Physical box is running Filezilla FTP Client (default settings) Physical box is uploading a big file to FTP server Transfer speed (as observed by Windows Task Manager on both machines): ~11MB/s (bad) Physical box is downloading that file from FTP server Transfer speed (as observed by Windows Task Manager on both machines): still ~11MB/s (bad) Could it be disk performance issue? Test2: Physical box is running ntttcpr.exe -a 6 -m 6,0,VM_IP_ADDRESS VM is running ntttcps.exe -a 6 -m 6,0,PHY_BOX_IP_ADDRESS Transfer speed (as observed by Windows Task Manager on both machines): ~11MB/s (bad) Could it be switch performance issue? Test3: physical box is running vSphere Client I open Summary Storage datastore Browse Datastore... from physical box and upload a file to datastore Transfer speed (as observed by Windows Task Manager on physical box): ~26-36MB/s (good) Could it be a vm specific issue? Test4: Installed ntttcp to another vm on the same esx server Measured network performance between vms on the same esx server with NTttcp Transfer speed (as observed by Windows Task Manager on physical box): ~90-120MB/s (excellent :) Test5: I have another esx server on the same site, connecting to the same datastore and same switch. Those two ESX servers have both 2 NICs. One NIC goes to switch while the other goes directly to the other ESX server. vMotioned one of the testing vms off to the other ESX host Measured network performance between vms on different esx servers with NTttcp Transfer speed (as observed by Windows Task Manager on physical box): ~11MB/s (bad) While I'm aware of these: ESXi 4.1 slow file transfer ESXi 5 network performance is slow Debian Etch and ESXi slow network speeds VMWare ESXi slow file copy to guest they did not help (or I must have been missed something)

  • Windows 7 BSOD when changing power plan

    - by dd5
    i have a strange problem. When i want to change the power plan on my laptop from High performance to Balanced, Windows freezes and i get bsod. The power plan settings are all default. Laptop specs: - Intel Core i3 330M/350M - Intel® HM55 Express Chipset - DDR3 1066 MHz SDRAM 8GB - ATI Mobility™ Radeon HD5730 1GB DDR3 VRAM - Intel SSD330 128gb - Windows 7 Home premium I've searched the internets but couldnt find a similar issue. BSOD first started when i installed this SSD and stopped when i've updated the chipset controller driver then started again yesterday when i wanted to change the power settings plan.Minidump file here. Any help with this weird issue appriciated, thanks. Edit: - i've ran Memory diagnostic tool, - Intel SSD diagnostics - and updated the firmware to 3.2.1. Non of these steps worked or shown signs of errors - but still got BSOD when changing power plan settings. After analizing the dump file via osronline.com here a first few lines: CRITICAL_OBJECT_TERMINATION (f4) A process or thread crucial to system operation has unexpectedly exited or been terminated. Several processes and threads are necessary for the operation of the system; when they are terminated (for any reason), the system can no longer function.

  • How can I format an SD card with a more robust Linux-usable filesystem with a specific cluster size for better write performace?

    - by Harvey
    Goal: microSD card formatted... for best write performance for use only with embedded Linux for better reliability (random power failures may occur) using an 64kB cluster size I'm using an 8GB microSD card for data storage inside an embedded Linux/ARM device. The SD card is not removable. I've been using ext3 instead of the pre-installed FAT32 because it seems to better handle random power failures during writes. However, I kept noticing that my write performance is always best with the pre-installed FAT32 from Kingston. If I reformat the card with FAT32, the performance still suffers. After browsing wikipedia, I stumbled upon the following comment saying that some cards are optimized for specific cluster sizes. In my case, the Kingston comes pre-formatted for an 64kB cluster size. Risks of reformatting Reformatting an SD card with a different file system, or even with the same one, may make the card slower, or shorten its lifespan. Some cards use wear leveling, in which frequently modified blocks are mapped to different portions of memory at different times, and some wear-leveling algorithms are designed for the access patterns typical of the file allocation table on a FAT16 or FAT32 device.[60] In addition, the preformatted file system may use a cluster size that matches the erase region of the physical memory on the card; reformatting may change the cluster size and make writes less efficient.

  • KVM and libvirt: How to configure a new disc device to an existing VM?

    - by initall
    I've got an Ubuntu 9.04 server running two VM's. In /etc/libvirt/qemu/machine1.xml two disk devices are defined like this: <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file' device='disk'> <source file='/vserver/machine1/disk0.qcow2'/> <target dev='hda' bus='ide'/> </disk> <disk type='file' device='disk'> <source file='/vserver/machine1/disk1.qcow2'/> <target dev='hdb' bus='ide'/> </disk> I need more storage space in at least one of the devices and thought about adding a third hdc device by simply adding one with same style as above and re-organising my mount structure (The virtual sizes of the current qcow2 files are unfortunately limited.) My problem is that reloading libvirtd and restarting the VM do not result in a new visible device (checked with fdisk). I'm aware of extending an existing qcow2 file (converting to raw format, cat-ing/adding the new one, using smth. like gparted) - but only as a last resort. Hopefully it's something very simple I'm missing?

  • Can't install mysql 5.1 on a windows machine because the last install left artifacts.

  • AWS own email domain and some generic questions

    - by John Brunner
    I'm getting started with Amazon Web Services and I have a few question I'm not sure about. As every (company) webpage I want to use an "[email protected]" email adress, but how is that done? I looked up at godaddy.com (for domain registration), the offer me an email adress like I want, but for 3 dollars per month. Is this possible with AWS? Because at AWS you have just a complex domain which is not very userfriendly or serious. Also I want to host my dynamic webpage on the amazon cloud, but I'm not sure if I'm doing that right. I've read many guides, and all I know is that I have to purchase a Elastic Compute Cloud, and a Simple Storage Service... and every guide is working with the basic linux package, why not Windows? Is it more expensive? I just want to host a mySQL Server for the dynamic webpage, which is reached over a normal domain. And one last question, if I sign up for an AWS account it asks me for an email account. But I found it a little bit unserious to write there my free-webmailer-adress... How is it done the normal way? Thanks in advance! Best regards, john.

  • How to find out what is causing a slow down of the application on this server?

    - by Jan P.
    This is not the typical serverfault question, but I'm out of ideas and don't know where else to go. If there are better places to ask this, just point me there in the comments. Thanks. Situation We have this web application that uses Zend Framework, so runs in PHP on an Apache web server. We use MySQL for data storage and memcached for object caching. The application has a very unique usage and load pattern. It is a mobile web application where every full hour a cronjob looks through the database for users that have some information waiting or action to do and sends this information to a (external) notification server, that pushes these notifications to them. After the users get these notifications, the go to the app and use it, mostly for a very short time. An hour later, same thing happens. Problem In the last few weeks usage of the application really started to grow. In the last few days we encountered very high load and doubling of application response times during and after the sending of these notifications (so basically every hour). The server doesn't crash or stop responding to requests, it just gets slower and slower and often takes 20 minutes to recover - until the same thing starts again at the full hour. We have extensive monitoring in place (New Relic, collectd) but I can't figure out what's wrong; I can't find the bottlekneck. That's where you come in: Can you help me figure out what's wrong and maybe how to fix it? Additional information The server is a 16 core Intel Xeon (8 cores with hyperthreading, I think) and 12GB RAM running Ubuntu 10.04 (Linux 3.2.4-20120307 x86_64). Apache is 2.2.x and PHP is Version 5.3.2-1ubuntu4.11. If any configuration information would help analyze the problem, just comment and I will add it. Graphs info phpinfo() apc status memcache status collectd Processes CPU Apache Load MySQL Vmem Disk New Relic Application performance Server overview Processes Network Disks (Sorry the graphs are gifs and not the same time period, but I think the most important info is in there)

  • Understanding RedHats recommended tuned profiles

    - by espenfjo
    We are going to roll out tuned (and numad) on ~1000 servers, the majority of them being VMware servers either on NetApp or 3Par storage. According to RedHats documentation we should choose the virtual-guestprofile. What it is doing can be seen here: tuned.conf We are changing the IO scheduler to NOOP as both VMware and the NetApp/3Par should do sufficient scheduling for us. However, after investigating a bit I am not sure why they are increasing vm.dirty_ratio and kernel.sched_min_granularity_ns. As far as I have understood increasing increasing vm.dirty_ratio to 40% will mean that for a server with 20GB ram, 8GB can be dirty at any given time unless vm.dirty_writeback_centisecsis hit first. And while flushing these 8GB all IO for the application will be blocked until the dirty pages are freed. Increasing the dirty_ratio would probably mean higher write performance at peaks as we now have a larger cache, but then again when the cache fills IO will be blocked for a considerably longer time (Several seconds). The other is why they are increasing the sched_min_granularity_ns. If I understand it correctly increasing this value will decrease the number of time slices per epoch(sched_latency_ns) meaning that running tasks will get more time to finish their work. I can understand this being a very good thing for applications with very few threads, but for eg. apache or other processes with a lot of threads would this not be counter-productive?

  • Bacula virtual backup job doesn't run, no output?

  • How do I rename my old Program Files folder?

    - by SteveJ
    I installed a new SSD as my boot drive (C:), installed a fresh version of Windows 7 64-bit, and kept my existing SATA drive in the system (D:). I want to keep using my D: drive for file storage (no sense filling up the SSD with stuff that isn't performance critical) and I haven't formatted the D: drive because there's stuff on there I want to keep. I also want to create a new "D:\Program Files" folder so I can install apps that aren't performance-critical there. So I decided I'd rename the existing "D:\Program Files" from my old Windows install to "D:\Old Program Files" and then create a new "D:\Program Files" directory. Easy, right? I can see "D:\Program Files" just fine in Explorer. I right click, select Rename, and type "Old Program Files." I get the alert that says I need Admin permission to do this, so I press the confirm button with the shield. But the folder still appears as "Program Files" in Explorer. I jump out to the command line, and it appears as "Old Program Files" when I do a dir. I can even do mkdir "Program Files" and when I do a dir they both appear. But in the Explorer GUI, it looks like I have two "Program Files" folders. This will be confusing during app installation because I won't be able to tell which one is which. I've tried poking around in the properties tab of the old folder, but can't find anything that would explain what's causing the issue. How do I rename the old Program Files folder?

  • Updated my WAMP Server and MySQL is eating up 580mB of memory

    - by Jon
    I updated my dev-box's WAMPSERVER, and along with updating PHP and Apache, MySQL updated to '5.6.12'. After doing that, I copied the data folder from my old (5.1.36) install to the new one and now MySQL takes up 580mB which is way too much, since I'm the only person using it (Locally) and there are only 20 or so databases on it, none of which have 'memory' tables.

  • Small store infrastructure - where to begin?

    - by KevinM1
    It looks like my older brother is about to change jobs - from lawyer to shooting range proprietor - and since I'm the family 'computer guy' I have the task of coming up with and setting up the in-store equipment. Only problem, I don't know how to start or where to look. I'm a web programmer, not an IT specialist. To that end, I figured I should ask the pros. Users: 3 (myself, my brother, and his business partner) Equipment: 1 Windows (likely 7) desktop for POS software, 1 Windows desktop/laptop for backroom use (bookkeeping, etc.) Other: ?? I'm looking for a reliable and, well, idiot-proof way to handle backups. Neither my brother nor his business partner are tech savvy (A web browser, email, MS Word and Excel are about the extent of their knowledge), so I need something they can handle. On-site would be preferable to off-site, given my brother's hesitance to have sensitive business data be handled by an outside source. I'm also looking for a small on-site server. I estimate that, at most, only 2-3 users will need access. A linux solution would keep costs down, but I'm concerned about Windows <- linux interoperability. Would the store security cameras' storage be handled by the security company, or would we have to stream that data to our own server? I know from my own experience with personal security that the company gives/loans a recording device to the home owner, but I'm not sure about business security. I know this sounds like a shopping list, and it's pretty vague. I wish I could give more detail, but between my own ignorance and things not being 100% nailed down on the business end, I'm a bit stuck. At the very least I'd like a nudge - links on a place to start, what to look for, things I need to think about, etc. - for this endeavor. Thanks.

  • Accidentally dd'ed an image to wrong drive / overwrote partition table + NTFS partition start

    - by Kento Locatelli
    I screwed up and set the wrong output for dd when trying to copy a freenas iso, overwriting the wrong external hard drive. Ironically, I was trying to setup a freenas server for data backup... External drive is only used for data storage, system is entirely intact Drive had a single NTFS partition filing the entire device (2TB WD elements) Drive originally had an MBR partition table. Drive now shows as having a GPT, presumably from the freenas image. Drive was mounted at the time, with maybe a couple kB of data written/read after running dd Drive is just a few months old and healthy (regular SMART / fs checks) I have not reboot the OS (crunchbang) /proc/partition still holds the correct information (and has been stored) Have dd's output (records in / out / bytes) testdrive did not find any partitions on quick or deep search running photorec to recover the more important data (a couple recent plaintext files that hadn't been backed up yet). Vast majority of disk content ( 80%) is unnecessary media files. My current plan is to let photorec do it's thing, then recreate the mbr with gparted and use cfdisk to create another NTFS partition using the sector information from /sys/block/.../. Is that a good course of action (that is, a chance of success)? Or anything else I should try first?

  • ActiveDirectory user files aren't being shared? [on hold]

    - by Ryan
    I'm taking a class in college and my current project is to setup Active Directory. So I have two VMs, one is Windows Server 2008 R2 and the other is Windows 7. I setup the domain team15.net (this is the FQDN for the forest) on the W2008 server machine. And then I connected the Windows 7 machine to the team15.net domain, and now I can login to the administrator account on the W2008 machine by using TEAM15\Administrator for the username. However, any files that I add in Windows 7 while logged into TEAM15\Administrator are NOT shown in the Windows 2008 machine. Is this normal? It seems like any files I add to this user in the domain only exists for the machine that I'm currently using. Is it possible to change this so all files for all users are synced to all computers in the domain? If not then what are alternatives? I noticed that back in high school we also used domains but there was a shared drive E:\ that you had to store your files because if you put them on in the desktop instead then they would suddenly disappear once you logged out and back in. How can I setup a shared drive? and which computer would provide the storage for this drive?

  • Will these instructions work when turning of journaling on an ext4 SSD?

    - by snowlord
    I have an Acer Aspire One with an SSD for storage. I recently installed Ubuntu on it and chose ext4 for my filesystem. Then I read that journaling on an SSD isn't the best idea, so I will try to disable journaling and I have found these intstructions (from http://fenidik.blogspot.com/2010/03/ext4-disable-journal.html): # Create ext4 fs on /dev/sda10 disk mkfs.ext4 /dev/sda10 # Enable writeback mode. This mode will typically provide the best ext4 performance. tune2fs -o journal_data_writeback /dev/sda10 # Delete has_journal option tune2fs -O ^has_journal /dev/sda10 # Required fsck e2fsck -f /dev/sda10 # Check fs options dumpe2fs /dev/sda10 |more For more performance add fstab opions: data=writeback,noatime,nodiratime i.e: /dev/sda10 /opt ext4 defaults,data=writeback,noatime,nodiratime 0 0 I will use them on my boot partition. Are there any particularly bad parts here, or are there any missing steps? Will my boot partition be fit for being on an SSD after this? Or should I consider switching to ext2, or even reinstall it all and choose ext2 at partitioning time (I'd rather not though, since I've configured quite some stuff already)?

  • Mac Finder: WD My Passport won't mount

    - by Matt
    I really need your help. I have a WD My Passport 650GB (with Firewire and USB). I'm using it for almost a year now and it always worked fine. While underway I simply plug it in via Firewire - at home I connect it to my Airport Extreme to have it available as a network storage. Today I connected the hd to my macbookpro (via firewire) and NOTHING. The hd is starting (clearly making a sound and the power-indicator is flashing) but it won't appear in Finder. I also tried it with USB - no sign. I ran Disk Utility and tried to repair the disk. At first try I got a red error line saying that something is wrong with the "headers". However the repair completed with a success message saying that everything is ok. I also verified the hd. Also with a success message. I did that a few times again and unplugged it in between. Never got the error with the headers again - it's always completing and saying everything is ok. However I can't mount the drive. That is what Disk Utility is showing. Any ideas on that? I really need the files on that hd. thank you in advance!

  • How do I fix error 1303 during TI Connect install?

    - by smoth190
    I recently purchased a TI-84 Plus graphing calculator, and I'm trying install the TI Connect software in order to connect the calculator to my computer via the USB cable. Unfortunately, I'm getting this error while trying to install the program: Error 1303. The installation has insufficient privileges to access this directory: E:\Data\Timothy\Documents\MyTIData. The installation cannot continue. Log on as administrator or contact your system administrator. However, my account is the only account on my PC, and it has administrative privileges. I've also tried running the installer with Run as Administrator, but with no luck. If I create the folder MyTIData manually, I receive this error: Error 1317. An error occurred while attempting to create the directory: E:\Data\Timothy\Documents\MyTIData I've reapplied the security settings to the E:\Data folder (and all its sub-directories) to Full for my account. I've also gone into Computer Management, and given SYSTEM full privileges for the entire disk. I've also logged out, logged back in, restarted, etc. but still, no luck. Now, I should mention that my Documents folder is not at the default location. I changed it due to my C: disk being a 90GB SSD, so I moved all my personal data onto the extra storage disk (which is ~1TB). I don't know if that is causing the issue, but it can't hurt throwing it out there. So why can't I install this program? Google'ing the problem brings up this error for various other installers (such as Visual Studio and Microsoft Office), but nothing for TI Connect. All the solutions are the same: Give the folder Full privileges...but I've already done this! I've also tried running the installer with and without the calculator plugged in, but it didn't change anything. In the prompt that contains the error, repeatedly clicking Retry or waiting a few moments before clicking Retry also produces no result.

  • Chrome pop-up blocker fail?

    - by Count Zero
    I have this problem since just a few days. I've been a heavy Chrome user for several years, but it never happened before: Sometimes absolutely uncalled for pop-ups appear, when I click something absolutely legit. It seems to happen at a very precise rate of two pop-ups every hour or so. The pop-ups are not very varied, it seems to be a fixed set of some 4-5 ads. At first I thought I caught some malware, but after a full scan with Malwarebytes Anti-Malware, I found absolutely nothing. In addition the problem exists only with Chrome. When I use Firefox, this never ever happens. What is even more puzzling is that it happens on both of my rigs and started on the same day. I have a removable storage that I dock to both of them and access one machine from the other via RDP, but still... It seems this is a problem that others face too. See this Google forum and here. Could it be that the latest Chrome build is just acting up? (Just in case it matters: I run Chrome version 24.0.1312.57 m on Win 7.)

  • How to access previous VHD versions of system backup?

    - by feklee
    Quote from the 31 Oct 2009 TechNet article "Learn more about system image backup": During the first backup, the backup engine scans the source drive and copies only blocks that contain data into a .vhd file stored on the target, creating a compact view of the source drive. The next time a system image is created, only new and changed data is written to the .vhd file, and old data on the same block is moved out of the VHD and into the shadow copy storage area. Volume Shadow Copy Service is used to compute the changed data between backups, as well as to handle the process of moving the old data out to the shadow copy area on the target. This approach makes the backup fast (since only changed blocks are backed up) and efficient (since data is stored in a compact manner). When restoring the image, blocks will be restored to their original locations on the source disk. If you want to restore from an older backup, the engine reads from the shadow copy area and restores the appropriate blocks. For the last days, a daily system backup of drive C: to drive E: has been scheduled and run by Windows 7 Backup and Restore. Drive C: currently holds 233 GB of data, which fits comfortably on drive E:, a 1 TB drive, with 727 GB of free space remaining. How do I access the previous version of a VHD? I right clicked on files and folders in E:\WindowsImageBackup, and I looked for Previous Versions but always: There are no previous versions available

  • HP/Lenovo alternative to Buffalo iSCSI TerraStation?

    - by Robin Day
    I'm looking at virtualising some of our infrastructure in order to allow for more resiliance and future expandability. We have successfully virtualised on single servers with Direct Attached Storage and are now looking for a more future proof solution using a high powered host (or two) and a SAN (or two). I'm thinking that the host machine will probably be an HP ProLiant DL360 G7 (all of our exisiting infrastructure is HP). Unfortunately, I am new to the world of SANs. From what I can see, the Buffalo Terrastation III is all I would need in order to setup an iSCSI SAN for VMWare to use. However, I'm a little reticent to go that way as it's a bit too "entry level" for my liking. In particular I would be very keen for more redundancy, power, networking, etc. I'm also very aware that you "get what you pay for". Therefore, can anyone reccommend equivalents from the big boys? HP/Lenovo? I have searched high and low on the HP site and seen many options but am struggling to work out if it is all the hardware I will need. Some options appear to need separate controllers from disk enclosures, etc.
