• Tape Storage - How do I setup a tape backup system for use with my NAS

  - by John Himmelman

  I currently have a QNAP NAS with a raid 5 config (~600gb storage) but don't have a reliable backup solution. I've heard great things about tape backup systems (reliability, durability, etc..). How can I go about setting up a tape backup system? The tape drives seem very expensive (1k+ for a decent one, more than the price of my NAS). What are the important specs to compare and features to take into consideration? Edit: Does anyone have links to some good resources? There is a ton of articles, guides, and sites on this subject, not sure where to start.

• How to recover bitlocker encrypted partition that is now 'unallocated'/'free space'?

  - by Atishay Jain

  My hard drive had 5 partitions(including 1(some 4-5GB) bit locker encrypted one). When I used disk mgmt I could view 2 partitions(24.4GB and 8.94GB) in green colour labeled Empty space. So, I wanted to merge them and I used minitool partition wizard for the purpose. I don't know, what that software did, but all I was left with 2 partitions and lots of green free space. I recovered 2 partitions using EaseUS partition master, but the bitlocker encrypted partition cannot be searched by it(and also minitool partition recovery). Now, the disk mgmt shows 2 free space partitions of 28.36GB and 8.94GB respectively. Here is a screenshot http://s14.postimage.org/4tvij041t/Screen_Shot003.jpg Please, tell me a way to recover the bitlocker encrypted partition that is showing as a free space in disk management. P.S. - It contains very important data.

• Torrents: Can I protect my software by sending wrong bytes?

  - by martijn-courteaux

  Hi, It's a topic that everyone interests. How can I protect my software against stealing, hacking, reverse engineering? I was thinking: Do my best to protect the program for reverse engineering. Then people will crack it and seed it with torrents. Then I download my own cracked software with a torrent with my own torrent-software. My own torrent-software has then to seed incorrect data (bytes). Of course it has to seed critical bytes. So people who want to steal my software download my wrong bytes. Just that bytes that are important to startup, saving and loading data, etc... So if the stealer download from me (and seed it later) can't do anything with it, because it is broken. Is this idea relevant? Maybe, good torrent-clients check hashes from more peers to check if the packages (containing my broken bytes) I want to seed are correct or not? Thanks

• Generating a record of the full(-ish) package management state

  - by intuited

  I'm about to make some system changes and I'd like to have a record of my current happy system state. Is there a convenient way to create a record of this? I'd like to keep track of info like currently installed packages and their versions which packages are pinned at what version which source (as in /etc/apt/sources.list) they were installed from whether they were installed directly or automatically installed as a dependency of a different package "unknown unknowns": ie stuff that I don't know that I should be keeping track of but which may be important when trying to figure out why something doesn't work In short, I'd like to keep as much of the aptitude database as possible. What's the best way to do this? It would be nice if the resulting records were easily readable, though this is not really essential. It would be extra nice if it were readily versionable through an SCM tool like git. There is a superuser question that partially answers this, but it only provides the list of currently installed packages.

• Small web server hardware advice

  - by Dmitri

  We need to build a new web server for our organization. We have around 100 hundred small traffic web sites, so our hardware requirements are not too tough. We run CentOS 6, Varnish+Apache, PHP, MySQL, Typo3 CMS for most of websites. Here's a hardware we want to buy: SuperMicro X9SCA-F-O (we need to have a remote management capability) (or better X9SCM-F?) Intel Xeon E3-1220 v2 2*4Gb DDR-III 1600MHz Kingston ECC (KVR16E11/4) (currently we have 4gb, and it feels like enough, so no reason for 16gb yet). Procase EB140-B-0 (1 unit) PSU 350W Procase MG1350, Active PFC We already have: Intel 335 120GB SSD (for OS, databases and important websites). 2*2tb WD Green RAID1 (for other data and backups). Does it look like a reasonable choice for our needs? Any issues with hardware compatibility? Any other notes?

• Locking down a box on the web

  - by glowcoder

  I'm a Java developer who is looking to put a game on the web. I'm not much of a web or server guy, though, and frankly I seem a little lost at where I should start with putting something on the web. My application works fine on my machine, and I'm sure I can make it work fine on any box I put it on. But the security of that box is pretty important. If I sign up for a standard hosting package (let's say from GoDaddy or something) can I simply tell them "make port 12345 open for communication" and let them handle the rest of the security details? If I can't, what are the things I'm going to need to know to prevent my game server from getting hacked to shreds? (Links to solid resources fine by me!) Thanks!

• PC BluRay - Multichannel HD Audio output

  - by sheepsimulator

  When playing a BluRay movie on a PC (any OS, Mac/Win/Linux), I have some questions about audio output: When playing a BluRay disc on the PC using a BluRay player program, can it decode the multichannel (7.1) LPCM/ Dolby Digital Plus / Dolby TrueHD / DTS-HD / DTS-HDMA soundtracks in their HD formats (ie, without downmixing to Dolby Digital or DTS or PCM) and output the audio directly to the soundcard's 7.1 line-level analog outputs? Is it possible to bitstream the the multichannel (7.1) LPCM/ Dolby Digital Plus / Dolby TrueHD / DTS-HD / DTS-HDMA soundtracks in their HD formats (ie, without downmixing to Dolby Digital or DTS or PCM) over the HDMI output to a receiver when using a BluRay player program? I'd kinda like to know. I'm contemplating building a home theater PC, and the above functionality is important. I'd prefer that #1 is possible, actually, because it would mean I wouldn't have to buy a receiver.

• Error during access to .ashx page in IIS 7 on windows 2008

  - by Rodnower

  Hello, I have web site on IIS 7 on Windows 2008, when I try to access the "page" (that correctly bound to namespace in web.config) I get error: "The required page cannot be accessed because the related configuration data for the page is invalid". Very important to say that on windows 7 I have this working. May be this is because I don't see ASP.NET area in management window? If yes, can yo tell me how I install ASP.NET on IIS 7 on windows 2008? Thank you for ahead.

• Global hotkeys: songbird on KDE

  - by alpha1

  I'm running songbird on opensuse 11.2 KDE 4.3.1 on my EEE pc. On windows, there is a hotkey thing inside Songbird, so i set META F9,10,11,12 as media keys and it work just fine. On linux, there is not hotkey thing in songbird, and I would like to set those same hotkeys. I've played around with the Amarok Hotkeys, which are now setup that way, and looked in all the KDE shortcuts, but cannot find a way to add a new program and new hot keys. I know its possible, I did it before once, but the KDE shortcut programs have changed and I no longer see the stuff i used to do it before. I'd like to do the same to banshee at some point, but Songbird is the important program. Any Ideas? Any way to set those keys to generic media buttons?

• How do I make a VMDK format virtual hard drive from a physical partition on a disk?

  - by Ahmad

  I have a 320 GB HDD, which actually only has an 80 GB NTFS format partition which was being used by a Windows 7 system ... I want to create a VMDK format clone of this partition, so that I can use it with VMware .. However, tradition VMDK creation programs normally make a VMDK for an entire disk, whereas I just want to make a VMDK for the one 80 GB partition ... This is important because the other 240 GB on the physical source HDD is just unallocated area, and including that in a VMDK file is just a plain waste of space .. So how to make a VMDK file for a specific partition ? Any tool available for this ?

• How quickly do I need to complete the installation of Windows updates once they're available?

  - by DragonLord

  I know that Microsoft publishes most updates on the second Tuesday of each month. While I understand that it is important to install security updates as soon as possible, do I place my computer at a significant risk if I wait more than a few hours after the updates are available to install the updates and restart the computer to complete installation? I'm asking because 1) I can't always restart the computer immediately after the system prompts me to do so; and 2) the download process sometimes has to be manually started late in the day when I remember, much later than when they're released at 01:00 PM EST/EDT, because Windows Update only seems to check automatically once per day and does so as soon as I connect to the Internet. Ideally, answers should be detailed and objective, with citations to references as appropriate.

• "the user profile service failed the logon"

  - by crazybmanp

  "the user profile service failed the logon" i had gotten this error when trying to login last night. i looked it up online and found that this was caused by an error (that is still unfound, apparently) that is causing windows to mark profiles as backup, and that the best way to fix this error is to do a system restore from the repair your computer special boot option. what i would like to know is if there someone happens to know the cause of this error, as i would not like it to happen again. Computer specifications OS: Windows 7 hard-disk check completely clean "repair startup" scan and fix: clean, no problems virus scans with kaspersky: clean (while not the usual information for specifications, i felt this info was more important for this case, any other information can be asked for.

• How can I tell if my Amazon Windows instance was an SQL Server AMI?

  - by Aligma

  I want to purchase some reserved instances, because I have several instances already created and running 24 hours a day. When I go to purchase a Windows instance, I can see 3 options, Windows Windows with SQL Server Standard Windows with SQL server Web I don't know which of these was used to create the original instance. Is there a way I can find out? My assumptions: the instance type is is important because as far as I understand, the way to purchase a reserved instance is to first have a running instance, and then purchase a matching reserved instance. The reserved instance is not itself a new machine, but a kind of contract between you and Amazon to pay for an instance for 1 or 3 years, at a discounted rate. The contracted, reserved instance will "offset" one matching running instance where they have the same size and platform. Please feel free to correct me if these assumptions are incorrect.

• Network attached external harddrive from another computer.

  - by Paul Knopf

  I have a server that is setup in raid. It is on the same network as my main computer. I would like to have some of the memory on my server to act as a network attached drive on my main computer. Basically, I want it to be a new data drive (similar two C:\, but 2nd drives are mostly E:). That way, I can reformat my main computer without loosing any important data. And the data that is saved (on server E:\ drive) is secured via raid mirroring.

• I found two usb sticks on the ground. Now what?

  - by Stefano Borini

  As from subject. I want to see what's inside. I am seriously interested in finding the owner if possible and returning them, but I am worried it could be an attempt at social engineering. I own a macbook intel with OSX 10.6. It is a very important install. What would you do in my situation if you want to see the content without risks ? Any proposal welcome. Edit: I decided not to plug them in, and I brought them to the hotel reception. They will forward it to the police.

• IIS 7.5 Request Filtering logs versus UrlScan 3.1

  - by Mouffette

  When IIS 7.5 Request Filtering blocks a request it seems to add an entry into the regular IIS web logs with a 404. a) Is there any way to send the detailed Request Filtering logs to a separate file? UrlScan could specify LoggingDirectory and keep this "noise" out of our real IIS logs b) Also, is there a way to get more information that Request Filtering blocked a request? UrlScan logged the rule that caused the denial as well as control over a redirection using RejectResponseUrl which was especially convenient in non-production sites. c) If these features are important is the recommended practice to still install UrlScan 3.1 on IIS 7.5 (Windows 2008 R2) and disable Request Filtering? Any guidance is appreciated.

• Disable (or switch off) a network interface on windows but keep the "plug and play"

  - by Leandro

  I'm looking for a good workaround to do this on Windows 7 and Windows XP: Disable or make ineffective the network interface (ETH, WIFI, any NIC). If the user connect his ETH cable, the network interface enable again. Important Notes to take care: I'm working with wmic on Win7 (through the command line) I'm working with devcon on WinXP (through the command line) I'm specifically working with the .NET Framework 2.0 on C# but this is just for informational purposes. I know that an event won't help me to detect it (if there is a way or workaround to do this I don't know it). The real problem is that when I disable the NIC, I can't know if the user connects his cable or has a wired network. This is why I am looking for a workaround. I'll treat suggestions as answers if no direct answer exists. I'll provide any extra detail necessary.

• Performance issue when configuring non HA VM in cluster

  - by laiys

  Hi, I saw this article http://technet.microsoft.com/en-us/library/cc764243.aspx Quote taken from the link “ Important It is recommended that you not deploy virtual machines that are not highly available on your host clusters. Although you can do this by using Hyper-V (VMM does not allow it), the non-highly available virtual machines will consume resources that otherwise would be available to the HAVMs What kind of resources (CPU,memory, NIC, etc) that non HA VM will consume? Just curious as not all VM (in production) not to be in Failover Cluster and Live Migration. If i put the VM into CSV but did not make it as HA, what impact does it make since i allocate same vCPU, vNic and VMemory into the VM. (not to mention that i lost failover feature). Curious to understand more about this. Please advise. Thanks

• Automatically insert Cell References from one Sheet into other Sheet in OOO Calc

  - by user123456

  I have a spreadsheet in Open Office 3.0 Calc. The spreadsheets consist of the first sheet and an arbitrary number of additional sheets, each collecting data for a specific month. The Month sheets have an identical structure. The first sheet is supposed to provide an overview to the most important numbers in the month sheets. What I would like to do is this: Whenever I add a Month sheet, I want it to appear automatically in the Overview sheet with the structure given below. So, for each Month sheet, copy or reference some of the cells into the Overview sheet: {Referenced Sheet Name} | Fixed Header1 | Fixed Header2 | Fixed Header3 Fixed Label 1 | {CellRef 1} | {CellRef 2} | {CellRef 3} Fixed Label 2 | {CellRef 4} | {CellRef 5} | {CellRef 6} I know how do to this for just one sheet by hand, but I have no clue how to make OOO do this automatically for me. Is it possible at all? Any help appreciated. Thanks.

• How can I stop sysprep from interacting with boot on windows 7

  - by Grofit

  I have recently had a laptop sent back to supplier for fixing a mainboard fault. I got it back today and every time it boots up I am faced with: "Setup is preparing windows for first time use" Then once it gets to the desktop I get the sysprep dialog come up asking if I want OOBC or Audit actions. I can close it, but it just keeps coming back, and I cannot find any startup or boot actions, even downloaded autoruns, and that cannot find anything to do with it. Ideally I do not want to format/fdisk as I have just spent hours installing everything on the laptop and I have my primary C:/ which has all windows and at worst case I can get rid of that, but I have a secondary partition D:/ which has alot of stuff I cant lose as its work related and important. Also to make matters more difficult I do not have a windows 7 disk, it was just pre-installed and they dont provide a disk. Any help would be great!

• Need to store and backup HD vid files. But need to access them alot.

  - by Mike

  I've had my 700 Gb HDD ever since I bought my computer so partitioning it is out of the question. What I need is a place to keep my HD vid files so when I edit, I don't get a long load time in the editing software. But I also need to keep a back-up of all my other important files which I haven't been doing. Should I buy an additional internal drive JUST for vid files and buy an external for backup of all my files? What are my best options?

• Virtual server hardware to simulate 3-4 node web farm

  - by frankadelic

  I would like to get a dedicated server to run VMWare, VirtualBox, or similar. On this box, I would like to host 3-4 virtual instances of Linux, to act as nodes in a web farm. Performance is not that important, this would only be for testing and experimenting. I need something sub $1000 (including tax/shipping). Can someone recommend a pre-built server that would do the trick? I am pretty ignorant of hardware so building one is not going to work for me. Also, would I need multiple network cards to simulate a web farm or can the virtualization software handle that for me. Thanks
