Debian :: Adding Backup Data Crashed The System?

May 12, 2011

I installed a fresh version of squeeze, with kde, and it worked fine. After I untarred my backup /home and /etc, things came to a standstill. I got a final ERROR code after /home. After a restart I got a 'fix your system' warning requiring a Control-D, which I couldn't type. I had used tar -xzvpPf ...... If I had included a -w, which asks for confirmation before overwriting data, could I have prevented this problem.

Hardware :: Recover Data From Crashed System?

Sep 18, 2009

I was running CentOS 5 with VMware Server on top of it. The system died and I'm trying to recover the VM images. The system died with a 'end_request: I/O error, dev' type message. It looks to me like the 2nd partition is wonky - is that correct? The GRUB portion does boot. I pulled the drive out and plugged it into my Ubuntu box to see if could get to the files. I ran 'fdisk -l' and found:

--------------------------
Disk /dev/sdb: 400.0 GB, 400088457216 bytes
255 heads, 63 sectors/track, 48641 cylinders

[code]....

To me this shows the GRUB boot partition and the system drive - correct? Next I created a mount point and tried 'mount /dev/sdb2 /mnt/recover' At that point I get a

mount: unknown filesystem type 'LVM2_member'

Here's where I'm a bit lost. I believe I need to add filesystem support to my Ubuntu box. I've been looking but have yet to find something that says the default filesystem of CentOS 5 is <blah>. After I do find that info, how do I install the filesytem support to read the drive?

Red Hat / Fedora :: Backup Data + System To Windows Share?

Sep 2, 2009

how to backup both the system and the data from my Red Hat Server to a share on a windows SBS server where the regular network backup will take it off-site every night. The Red Hat Server is basically a web server on the LAN using RAID 1 to ensure some redundancy in the discs and is used as an internal web server for an administration system.

The Windows SBS server is the domain controller and rest of the network is totally windows based. The SBS server has large discs which host all of the general data to be backed up and is controlled by a 3rd party IT company. We have a share created on the SBS Server which is to backup all of the information from the Red Hat box to ensure we can potentially restore the system quickly in case of a major problem.

The thorn here is that I am working on a different site to the Red Hat Box and have to do everything over SSH. the Red Hat server has Samba running but I have not used it to mount an external windows share? Is there an 'out of the box' backup software on the Red Hat server that I can control over ssh to do the job? The biggest worry for me is the backing up the system to a state where it can be popped on a disc and the system restored from the backup - or most of it anyway - enough to get the server back on its legs.

Ubuntu :: Rsnapshot - Automated Data Backup Of Remote File System

Aug 28, 2010

Rsnapshot is a software written in Perl to make backup of local and remote file system. The well proven rsync is behind this utility. rsnapshot does not need root user intervention to restore the data of a normal user. It does not take much space in your Backup server. It can be easily automated (scheduled) to make life easier. Just setup once and forget it configuration. Basically it takes snapshot of file system (or a part of) in regular interval such as hourly, daily, weekly and monthly.

This can be configured easily through a simple text based configuration file. The above task can be setup in a few easy steps in a few minutes. Two major tasks are configuring rsnapshot and openssh automatic login. To make the backup automatically, we need to automate the remote login in a secured way. This can be done through openssh tools. This scenario depicts backup of desktop (assuming that IP address is 192.168.0.100) data to a backup server. My desktop runs on Ubuntu 10.04 and backup server runs on Debian Squeeze. [URL]

Debian Configuration :: Crashed After System Update

Jan 23, 2011

I updated squeeze last night for the first time. It worked fine after 1st reboot last night. There was one reboot stalled at "hald" so I shut down and restarted. Worked ok 2nd time around

Today,upon login I got a string of taskbar notification (which I couldnt read as they all overlapped . I was able to see a kernel error message but couldnt report it (network was down) or save it (USB stick not recognised) Some programs worked, others didnt

I have the partedmagic rescue distro on USB stick so have those programs to use in order to fix the problem. Any idea how I can repair this? I tried fdisk for the hell of it. reported clean partition as predicted. I am using debian-testing-amd64-kde.

Debian Configuration :: Clock Readjusted After System Crashed - Cannot Reboot

Dec 20, 2010

I have recently come across a Debian installation page for powerpc: viewtopic.php?t=20481. It got me motivated to fix the Debian I have on my iBook G4. I have a Debian Lenny installed on my iBook G4 -- but I have been having some sort of problem (mostly likely due to hardware) which causes the system to crash. After the latest crash, the clock on iBook has been readjusted. For this reason, I cannot reboot Debian completely.

Every time I turn on the computer it begins the booting process but before I get to my desktop I encounter numerous error messages concerning my clock. After either OK'ing or canceling these error messages, I get to my desktop but the system by then is either frozen or else not working at all. Worse, I can't even turn off the computer since the upper right corner of the desktop is completely blank and I have no menu to turn off or reboot the system.

It took this computer to a local Apple store and they ran many different hardware diagnostic tests on it. They concluded there's "technically" nothing wrong with the computer. But they said although the system has successfully passed all hardware tests, there may still remain some complicated but slight hardware glitch/es which the hardware diagnostics could not pick up.

Ubuntu :: Adding The Panel - Gnome Crashed And Computer Won't Boot Correctly

Dec 8, 2010

I have a desktop computer running Linux Mint 9 with the Gnome desktop (not sure what version -- though by default Mint 9 comes with Gnome 2.30). Last night I tried adding a panel to the desktop by right-clicking on the existing bottom panel and selecting "New Panel". Please note that I've already got another panel at the top of the desktop on the left side on autohide and no expand.

When I added another panel, it placed a normal panel on the right side of the screen without any problems. When I right-clicked on the new right-side panel and selected "Properties", I changed the orientation to "top" (where there was already a panel, if you remember). After that moment, it seemed like the entire desktop environment crashed. Everything was completely unresponsive -- the only thing moving on the screen was the mouse. I couldn't do anything with the gui, not even shut the computer down.

Since the gui shutdown wasn't working, I switched to a different tty screen, logged in, and ran a shutdown command with the option to reboot. The computer shut down fine, and when it woke back up, the same problem was still there: Nothing loaded on the screen except for the background image and the mouse, which was still able to move but nothing else. I have the computer set up to automatically log me in, so I know it's not crashing before the user prefs are being loaded...

After restarting it again and getting the same result, I switched to a different tty screen, logged in, and tried messing around with stuff to no avail. I did notice, however, that the computer was becoming evermore sluggish, and something printed on the screen stating that a program had been terminated because of "not enough memory". It seemed like some process was consuming WAY too much RAM by itself or a program was accidentally forkbombing the computer. ...All because I added a panel...?

Ubuntu :: Hard Drive Read Only After Backup Crashed

Mar 13, 2010

I was busy making backups to my external hard drive just now, but Ubuntu crashed 10 mins into the backups. After rebooting the affected folders are now Read only, and I cannot add or remove anything. This is extremely annoying, I already threw away two USB flash disks because the same thing happened to me in the past. I don't want to throw away the external because it's far more expensive and packed with backups.

Symptoms: I can write or delete a file to the hard drive, in any folder, accept the folders that was being accessed when the computer crashed. I have tried to change permissions, but I get an error. I tried opening a terminal and sudo rm -r that folder, but I get a input/output error. I'm running Karmic. Backups were made by Back-in-time.

CentOS 5 :: Recovery From Crashed Hard Drive With No Backup?

Aug 4, 2010

Recently I built a web server for my clients to host in house. After talking with the web developer they informed me that i needed a CentOS computer with Drupal for them to design the website. This is my first Linux install and after spending hours upon hours configuring the server with FTP, SSH, and configuring our DD-WRT router with proper port forwarding we turned it over to the web designers to start work on the website.

A month goes by and the website is almost done, at this point we go to make a full backup of the hard drive. Due to a hardware problem it fried the circuit board of the hard drive. After attempting to recover the files myself we opted to send it to a HD data recovery facility to recover the information. We have received back a DVD containing the 2GB's worth of data from the CentOS hard drive. It contained 2 folders one for each of the partitions. I can view and see all the files on my windows machine and it appears that all of the data was recovered successfully. I harbored some hope that i could simply reinstall CentOS with the same account information and then just drop the recovered files on top of the new installation and have it start working.

I then reinstalled CentOS on another hard drive in the same computer and used the same credentials for installation. After i successfully booting into CentOS i turned off the machine and connected the hard drive it to my Windows bench machine. After booting into Windows i was unable to browse the hard drive. After doing more research and installing Ext2fsd i was able to see the 2 partitions CentOS had just created, but only able to access the Boot partition. After more research i discovered the default installation of CentOS creates a Raw file type for the 2nd partition and that is why i am having issues reading it inside of Windows.

I then downloaded a copy of Knoppix to see if this would allow me to write the old files over the new ones. After booting up the CD i could only browse to the /boot drive(and im not even sure if this is Knoppix's Virtual /boot or my CentOS /boot).

My question is what would be the best steps to recovery for my scenario? Can the files be placed to the drive and have everything restored? Is the only way to recovery thru reinstalling all applications and reconfiguring from scratch? How difficult is Drupal DB to recover in this type of scenario?

Ubuntu :: Get Data Off Crashed Installation?

Jul 21, 2010

A few months ago I did a clean install of the unbuntu desktop which I used to run an internal website. The OS was installed on one hard disk and two other hard disks I setup as a mirrored raid. Now when I start the computer I get a GNU GRUB commandline interface and I can't seem to get my installation up and running again. I've tried some of the suggestions for GRUB issues however I can't even get ls to work (gives me an error).

I am at the point where I don't really care about the OS installation but would desperately like to get the data off the raided disks and also a few files off the boot disk. I can't seem to work out how to do this using a liveCD, if I open the disk utility, select the raid and click "Start RAID array" I get a "Not enough components available to start the raid" error.

For the boot disk the major partition is a Linux LVM partition (and I assume the data I need is on that partition) however I cannot work out how to mount it. I really hope you guys can help me as the information is rather important.

Security :: Data Recovery Crashed ATA HDD

Jul 14, 2010

A friend has a embedded system (korg recorder) with a ata drive in it, that crashed. We are trying to come up with ways to retrieve the data off of the drive. I'm asking in security as this seems like it would be close to forensics, hence security. Hints on software for linux to help either recover files, move files, copy/clone the drive? I'm not so concerned about the korg's os on the drive, as we can create a new blank drive and install that, its the data that is critical, that needs to be recovered. The original korg os was only recognizing drives up to 100gbs so I'm guessing this might be a fat16 filesystem if that helps. Well, that and the program installed to the drive to run it in the korg is an exe.

Ubuntu :: XP Crashed Out And Couldnt Retrieve My Data

Jul 29, 2010

I have a laptop that had Windows XP on it - XP crashed out and I couldnt retrieve my data of it, despite booting up in safe mode, it just didnt want to do anything. So i thought i will load ubuntu instead then try and recover my data - bad move. Now my question is, can I still retrieve the windows data of the hard drive despite having Ubuntu installed on the same drive? I know on windows there is an app called File Scavenger that recovers deleted files even after loading a clean slate of Windows on it. Is there something like that for Linux? I had photos on it that has some real sentimental value. The rest of the data I dont care about. Just the photos. I didnt think before I reloaded it.

General :: Backup A Debian Based System?

Oct 8, 2009

Issue: I want to backup my system and be able to restore if/when my system crashes.

Setup: Thinkpad T61 running Sidux KDE3.

I want to back up the system files more than personal data. What I have found is that when I apt-get dist-upgrade the upgrade performs without error, but when I restart and login I get a black screen with a mouse. From the 'black screen' I can open yakuake with F12 and then launch applications and such from the command line. The point of this more troubleshooting right now. Later is so I won't need to do a complete reinstall.

What backup prog have you used that will backup the complete system and is easy to restore?

Debian :: Tarball System Backup Always Corrupts Libc6-dev?

Aug 3, 2011

With tar, it is possible to back up your desktop system like so (probably best done from runlevel 1 or a live medium):

# cd / # or wherever your root directory is mounted
# tar --exclude=dev/* --exclude=proc/* --exclude=sys/* --exclude=tmp/* --exclude=backup.tar.gz -czvpf backup.tar.gz .

Debian :: Best File System For Backup / Media Drive?

Aug 29, 2011

I'm setting up a Backup & Media server, which will be running debian. I will setup a small HD or SSD/CF card for the OS, and a MD raid for the data drives.The total size of the raid will be either 3 or 4TB, depending. Now, I need to figure out what filesystem to use on top of this raid.My criteria is as follows:

1. Support for large files. I can't imagine anything larger than about 1.2TB, but the 4GB of, say, fat32 just isn't enough.

2. Robust. I don't want it falling apart on me; nothing too unstable.

3. (and this is most important): Good Undelete support. I got burned recently when a software glitch managed to rm -rf my EXT4 drive. All the file data is still there, but all the metadata is gone. I *DO NOT* want that happening with this. I want to be able to do a "RM / -RF", immediately unmount it, and then recover *all* of the deleted data. Obviously, when data is overwritten it's overwritten, but I don't want to lose all my metadata if a "RM -RF" happens. FAT-32 is the model I'm looking at: You can usually recover deleted files if anything happens to the drive.

So, what are my options?EXT2 looks like a possibility. EX4 is *clear out*, unless there's some nice utility/mode that keeps a backup of all deleted metadata etc.

Debian :: Backup Purge Script - `/mnt/backup/subfolder': No Such File Or Directory

Fedora :: System Crashed During Yum Update

Jul 11, 2011

My system system suffers from frequent kernel panics, which I think are due to gnome-shell with the nVidia driver. (I see no panic message and nothing is logged, but I've enabled magic SysRq and it makes no difference.) Twice this has occurred during yum-update's install stage, which is making me wonder. Uum-update then complained about an unfinished transaction, so I ran yum-complete-transaction as suggested. I've also tried yum-clean-all and rebuilding the RPM database, suggested in other threads, but I'm still seeing the following errors on yum-update:

I don't know where these 32-bit packages have come from this is an x86-64 system and the only x86-32 stuff I've intended to install is the Adobe flash plug-in. Also the later dupes are different 64-bit versions. I've tried "package-cleanup --cleandupes" as suggested in this thread: [URL]. It wants to remove the old versions, but also wants to remove packages that depend on them, including clutter, so I cancelled that. The first time round I was left with a barely usable system and had to reinstall, which I'd rather avoid, especially if this is going to be a regular occurrence. I'm not familiar with RPM (or kernel panics for that matter).

General :: Fedora System Crashed During Yum

Jul 9, 2010

I was concerned about a number of duplicates reported by yum and was cleaning with package-cleanup (logged in remotely with ssh and vnc) when suddenly all the fonts turned to music and the system froze.

I had run F13 preupgrade as a test to see how it would go...(in case this is important) but had not rebooted yet...

Now when I boot I get the splash and the fedora droplet fills with white, though it gets progressively slower as it approaches the top. Eventually the infinite f appears but that's where it stays.

I have been able to boot to a live-usb stick w/F13. And after some shear panic, I discovered that the root partition is buried in lvm, in a 935 GB physical partition.

I have mounted the logical volume and dd if=/mnt/oldroot | gz > /ExternalBackupDrive/oldroot.gz

so that if I break things further there is a chance that I can get back to a working system.

Is it just that my bootloader doesn't know how to mount the lvm?

Where do I look for clues?

Is there a boot option that will let me follow the progress?

OpenSUSE :: Adding - Mounting New Drive & Recovering Corrupt Data

Mar 4, 2010

I have a Hard Drive that has a corrupted file system and i have tried the usual MS Windows fixes, chkdsk and a number of recovery tools inc Dos recovery tools and failed.

The Drive is an MS Windows drive with an NTFS file system.

chkdsk scans and after several hours fixing numerous problems eventually gives up and fails to complete.

The directory "My Documents" contains several GB of data and displays that this is true. When trying to access the directory, access is denied because its corrupt. Using Windows and Dos recovery tools i can view the contents of the directory sometimes! but cannot copy out any of the data, the applications return messages saying no can do basically.

I would like to try to use Linux to recover the data.

Problem number one is i have never tried to add a hard drive to an existing Linux system before, how do i go about adding a new drive?

The 2nd problem is, is there a Linux application that i can use to attempt to repair and recover the corrupt data on this drive or more specifically in the "My Documents" directory.
