• Can you recover from a backup with bad blocks?

  - by Macbook-Recovery

  The hard drive in my Macbook recently gave up while using it on the plane (dual prop, lots of vibration unfortunately). I have a backup of its contents from a few weeks ago, but there are files that aren't included in it that I would like to recover. As it stands right now, I have it plugged to my macbook by USB. Snow leopard recognizes it, but can't mount it. Therefore, tools like Diskwarrior and Techtools do not work. I started doing a clone of it with Data Rescue 3, but after 7 hours of activity (20% through the drive), it has copied 130 GB of the drive but reports all of the data as "bad blocks". My question is this: Is any data recoverable if the clone is completely composed of bad blocks?

• How to define a layered model for Storage Architecture ?

  - by Berkay

  i don't have enough knowledge about storage systems but have to tell my audiences about how storage works in organization data centers. For this purpose to keep things simple, first i want to show them a layer model then from top to bottom and then i want to explore all these layers. What i mean by layered model in storage architecture? i want to start my presentation something like that, first layer can be applications, application request a data from storage and then ... ... (the topics i want to cover are file sytems, metadata,the physical implementation of storage (das, nas etc.) ... the request comes to the storage device and storage device (depends on the technology) goes through the disk and disk send back the data using iscsi protol, we can say that the iscsi protocol managing the path between... ... if you help me explain these steps layer by layer by examples and key technologies to be defined, really appreciate it. thanks.

• Migrating data from SQL Server 2000 to SQL Server 2005

  - by Muhammad Kashif Nadeem

  I have to migrate existing data which is in SQL Server 2000 to SQL Server 2005. The schema of two databases is different. For Example Locations table in SS2000 is split into two tables and has different columns. This is one time activity. After successful migration I don't need old db anymore. What is the best way to transfer data from one SQL Server to another having different schemas? I can write stored procedures to fetch data from SQL Server 2000 and insert/update tables in SQL Server 2005. What about SSIS? I don't have any experience with this and is this better to create package of SSIS because I don't need this again and need to learn it first. Thanks.

• Sar data not collected for 10 minutes

  - by Ichorus

  We have a RedHat server whose only job is to run a JBoss server. Monitors said that memory usage spiked (we have the JVM limited to far less than the total memory on the system) and JBoss crashed. We restarted and everything seems ok now. Odd thing is that sar data for 10 min leading up to the crash is simply not there. Load average got up to the 50s. I have seen severely busy systems (350+ Load Average) still collect sar data. Does anyone have any idea what could cause sar to stop collecting data?

• recover lost files from sd card(digital camera)

  - by user23950

  How do I recover lost data from sd card? I already tried using: Photorec Recuva Tune up undelete Pareto data recovery chkdsk x: /F from here: http://superuser.com/questions/128259/how-to-recover-images-from-memory-card But none of them worked. I think I've only lost the data yesterday. And I haven't used the camera. So there's a possibility that it is still there. But the question is how I can recover the images? I think its lost when I tried to connect the digicam with the computer. But the camera froze so I tried to remove the batteries then try again.

• Stop RAID 5 from Initializing

  - by Antz

  Hi, I am trying to follow Ictinike's guide on Recovering Intel RAID "Non-Member Disk" Error found here, Ictinike's RAID recovery Guide I have recreated my RAID array as per the instructions. However my RAID array status is then automatically set to: INITIALIZE When I boot back into my Windows XP desktop, the Intel Matrix Storage Utility begins to "Initialize" my drives. This is a long slow process that will take about 20 hours. I suspect all my data will be lost. I have gone back into my bios and disabled my RAID controller to prevent any further initialization and data loss. I have read that initialization will cause data loss. I've also read somewhere that it won't. I am not so confident in the latter. Is there anyway to stop this initialization process so I can continue to follow the steps in the recovery guide? Some system specs: ABIT IP35 Pro Motherboard ICH9R on board RAID controller

• Migrating data from Oracle database to Pervasive .DAT files

  - by kaychaks

  The requirement is to migrate some tables with data from a Oracle database server to Pervasive database's .DAT file. Then those .DAT files will be used by a Pervasive database server. The restriction is that Oracle DB can not directly migrate to the Pervasive DB. It has to generate the .DAT files and then the new .DAT files will replace the old one for the Pervasive DB which will then use them for the new data. I was trying this task with SSIS. Exporting the Oracle table to a delimited .txt file and then creating a .DAT file from that text file. I can export the data from Oracle to .txt but I am not finding any way to migrate .txt to Pervasive .DAT? Is this the right approach? If not then please help with my problem.

• Is TrueCrypt robust against data corruption?

  - by Dimitri C.

  I would expect a TrueCrypt volume to be fragile when it suffers from data corruption. This could happen for example because the hard disk, CD or DVD start to deteriorate, or when an USB stick is unplugged while a write is in progress. On the TrueCrypt FAQ it is mentioned that this problem is limited because the data is encrypted in blocks of 16 bytes. However, I'dd like to know if this really so in practice. Is there anyone who has experienced severe data loss due to only small corruptions?

• Difference between sending data via UDP in Bash and with a Python script

  - by Kevin Burke

  I'm on a Centos box, trying to send a UDP packet to port 8125 on localhost. When I run this Python script: import socket sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) sock.sendto('blah', ("127.0.0.1", 8125)) The data appears where it should on port 8125. However when I send the data like this: echo "blah" | nc -4u -w1 127.0.0.1 8125 Or like this: echo "blah" > /dev/udp/127.0.0.1/8125 The data does not appear in the backend. I know this is horribly vague but it's UDP and it's hard to determine why one packet is being sent and the other is not. Do you have any ideas about how to debug this issue further? I'm on a Centos machine.

• Does WD Drive Lock encrypt the data?

  - by ssg

  I wonder if WD Drive Lock ineed encrypts the data on a Western Digital My Book Essential device or just puts a firmware-level password on the device. If it's just a password the data surely could be retrieved by a third party. I could not find anything on about that on user manuals. I found a blog saying "data is secured with AES256" bla bla but that doesn't say anything about if the password could be compromised or not. Because I don't see any delays when I add/remove the password. On the other hand when I enable BitLocker, it takes hours before it encrypts everything with my password.

• Run script when POST data is sent to Apache

  - by Nathan Adams

  Among my several years of running servers there seems to be a pattern with most spam activity. My question/idea is that is there a way to tell Apache to run a script when POST data is detected? What I would want to do is perform a reverse DNS lookup on the client's IP address, and then perform a DNS lookup on the hostname in the PTR record. Afterwards, perform some checks, excuse the pseudo-code: if PTR does not exist: deny POST request if IP of PTR hostname = client's IP Allow POST request else deny POST request Though I don't care about GET requests, even though they can be just as malicious, this idea is targeted towards spam comments which use POST data to send the comment data to the web server. In order to make sure there isn't much of a time delay, I would run my own recursive DNS server. Please do note, this isn't meant to be a sliver bullet to spam, but it should decrease the volume. Possible or impossible?

• How reliable is HDD SMART data?

  - by andahlst

  Based on SMART data, you can judge the health of a disk, at least that is the idea. If I, for instance, run sudo smartctl -H /dev/sda on my ArchLinux laptop, it says that the hard drive passed the self tests and that it should be "healthy" based on this. My question is how reliable this information is, or more specifically: If according to the SMART data this disk is healthy, what are the odds of the disk suddenly failing despite this? This assumes the failure is not due to some catastrophic event that impossibly could have been predicted, such as the laptop falling down on the floor causing the drive heads to hit the disk. If the SMART data does not say the disk is in good shape, what are the odds of the disk failing within some amount of time? Is it possible that there will be false positives and how common are these? Of course, I keep backups no matter what. I am mostly curious.

• Basic clarification about Limited FTP/sFTP users

  - by mattewre

  I would like to get some clarification about the correct way to create limited users to access to my VPS user as WEBSERVER with Nginix. I'm used to NOT install FTP and access via SFTP only. It is ok for every set up? this is what I usually do from to create a limited user called "admin" that should be able to have access via SFTP to the folder with the website data mkdir -p /var/www/mysite.com/ adduser admin adduser admin www-data chown -R root:root /var/www chmod -R 755 /var/www chmod -R 755 /var/www/mysite.com chown -R admin:www-data /var/www/mysite.com/ It seems not to be the correct way, I always have problems with permission when I upload some files (for example with Wordpress in general). I would like to create an user that does work exactly as the one that the "provides" give to their client when they buy an Hosting service (that is a FTP, I would prefer SFTP access). It is for personal user, but I think that a limited user is a lot safer to use then the "root" via SFTP.

• Apache configuration to accept all data

  - by ServerDown

  Hi, I have apache running on port 7979 to talk with a device that sends data to webserver and later will run php scripts to process and send reply xml. The problem now is that it sends data like POST HTTP/1.1 Content-Type:text/xml Content-Length:369 Followed by XML When apache sees this it gives a 400 error. Since the device cannot be changed is there any way to accept the full data sent from the device and write to some log? Currently apache simply keeps sending 400 errors back. If there was a way to log the entire xml or create some custom handler for 400 error then the xml could be read by a php script. Looking forward to solutions.

• Annotating Graphs From Textual Data

  - by steven

  I've got a graph that was generated from a data set that contains: (date, value, annotation) The annotation is a constant value [its either there or is blank] and I would like to add in the third bit of data into the graph I have. An example of this is in the image. The blue line is a graph of the (date, value) graph, and I would like to add in the red dots as graphing (date, annotation@value). Is there an easy way to do this in excel, without having to modify the appearance of the data?

• SCO Unix - finding and pulling data

  - by lxlxlxl

  We recently acquired a company that was running a legacy application on a SCO Unix box. I can tell that the app is running off of http, but its reporting and data export functions are limited and I'd like to find a master db or data source on the box that maybe I can migrate into something more useful. Any ideas how I could possibly find that? Would there be something in apache or startup scripts that might point to a master db? do Unix applications have standard data source locations? I'm not sure if I'm wording this right so apologies in advance.

• Ms Excel 2010 Importing Data in One ROW and getting sum particular CELL

  - by Omeshanker

  I am importing data by using .txt file to MS Excel and whole data is imported in ONE ROW. I want to get SUM of those values which corresponds to a particular Month.

• need advice for storing data setup hardware for client with 80TB per year of data footprint increase

  - by dasko

  hi everyone, i currently have a client that will be adding replicated data from satellite locations in the number of approximately 80TB per year. with this said in year 2 we will have 160TB and so on year after year. i want to do some sort of raid 10 or raid 6 setup. i want to keep the servers to approximately 4u high and rack mounted. all suggestions welcome on a replication strategy. we will be wanting to have one instance of the data in house and the other to be co-located (any suggestions on co-locate sites too?). the obvious hardware will be something like a rack mount server with hot swap trays and dual xeon based type processors. the use of the data is for archives of information, files will be made up of small file sizes. i can add or expand to this question if it is too vague. thanks for looking.

• writing data onto a linux live-dvd

  - by stanleyxu2005

  I have a server machine with a dvd-writer. I want to burn a linux live-dvd (openSUSE is preferred) with a pre-configured web server, so that after booting the web server should be ready to serve. The web server has a sqlite database (with very less data). But after rebooting the system, all data in the database will get lost. Is it possible to store all necessary data onto this live-dvd as well? If it were a usb drive. I would create two partition and mount the second partition with read-write permission. But I have no idea how to create two partition onto a dvd Any hint is appreciated

• Linux QoS: bulk data transmission during idle times

  - by syneticon-dj

  How would I do a QoS setup where a certain low-priority data stream would get up to X Mbps of bandwidth, but only if the current total bandwidth (of all streams/classes) on this interface does not exceed X? At the same time, other data streams / classes must not be limited to X. The use case is an ISP billing the traffic by calculating the bandwidth average over 5 minute intervals and billing the maximum. I would like to keep the maximum usage to a minimum (i.e. quench the bulk transfer during interface busy times) but get the data through during idle/low traffic times. Looking at the frequently used classful schedulers CBQ, HTB and HSFC I cannot see a straightforward way to accomplish this.

• Mounting LVM2 volume with XFS filesystem

  - by Chris

  Unfortunately I'm not able to access the data on my NAS anymore. I can't figure out why this is the case as I haven't changed anything. So I plugged one of the harddisks in my computer to access the data. What I did: kpartx -a /dev/sdc Now I should be able to access /dev/mapper/vg001-lv001 When trying to mount it I get: sudo mount -t xfs /dev/mapper/vg001-lv001 /home/user/mnt mount: /dev/mapper/vg001-lv001: can't read superblock Now I did a parted -l which gave me Modell: Linux device-mapper (linear) (dm) Festplatte /dev/mapper/vg001-lv001: 498GB Sektorgröße (logisch/physisch): 512B/512B Partitionstabelle: loop Number Begin End Size Filesystem Flags 1 0,00B 498GB 498GB xfs Does anybody have a solution how to recover the data?

• Mirror DFS configuration data between 2 servers/ sites

  - by Retro69

  I have 1 Windows 2008 R2 server in Site A running Domain Integrated DFS in 2008 mode with a Single Namespace with a large number of DFS Targets all configured to point to a share on our NetApp SAN. Step 1. I want to initially copy this configuration data across to a 2012 server in Site A preserving all the configuration data. Step 2. I need to mirror this configuration to a 2nd server in Site B so we dont have a single point of failure for the DFS namespace. For Example. A user in Site B would "connect" to the DFS server in Site B, but if that site was down, it would attempt to connect to the Server in site A and vice versa. Note im not interesting in replicating actual Data here, just the configuration. Our NetApp SANS have mirroring which take care of that. Is this possible? Many thanks.

• changing filesystem format from jfx to ext4 without losing data

  - by A.Rashad

  I have a fresh Lucid Lynx (Ubuntu 10.04) running on a laptop. where I defined the filesystems as: mount point / on ext4 (46 Gb) mount point /home on jfs (63 GB) swap as 3 Gb I left the machine over night to do some task, without AC power supply. next day in the morning I found it on standby, task completed, but filesystem was not reachable. it gave me I/O error it seems that there is a problem with jfs and standby. anyways, to avoid any hassle, I want to move this mount point from jfs format to ext4. can I do this without losing data and without the need to place the data in a temporary location until transformation is done? sorry to mention that, but I recall back in the windows days, we would change a FAT16 to FAT32 or a FAT32 to NTFS without having to lose the data. I hope this is available on Linux.

• Connecting office to data center via Metro-ethernet

  - by Eric

  I am installing a metro ethernet link from my office to my data center. The office will have a cisco 3750 with several vlans. The data center end will have a more complicated set up. The metro e from the office will connect to a 2960, which will have two other 2960s with a few vlans and a 2811 router connected to it for connectivity to our other environments and the internet. I am looking at implementing this by connecting the office 3750 and the data center 2960 with a dot1q trunk and doing all routing at the 2811. I will configure subinterfaces for gateways for each of the vlans on the 2811. I work for a small company and don't have much of a budget for an ideal architecture. I can post a simple diagram if needed for clarification. Is there anything I am missing here? I feel like I am forgetting something very basic and want to make sure I eliminate any boneheaded mistakes.
