General :: Most Recoverable Filesystem For Backup?
Jul 13, 2011
I want to backup a lot of files on an external 2TB USB and sit it in a cupboard for the next 10 years. Looking for the most reliable filesystem for this. I don't care about speed, journalling, UNIX permissions or any of that stuff. All I care about is in 10 years time when the hard disk plates are rusted and unreadable and the drive hardly functions, what filesystem will be the easiest to recover my data from. Not ruling out FAT32 either for its simplicity but maybe there's a better filesystem for the job?

Suppose I have a good backup of the / root filesystem. How do I recover the / root area? Suppose I have modified the root filesystem, perhaps I do an update some of the packages and regret it, and I want to get back to the system at the time of the backup. How do most linux people recover the root area of a system from a backup?
1) I wondered if I might put a System Rescue CD in and boot off it?
2) And then NFS mount the directory containing the backup? -In my case, I have made a good backup using rsync, to a directory elsewhere on the network.
3) And then, still booted off the System Rescue CD, mount the partition that contains the / root area in question?
4) Would I then clear or empty or delete the contents from the / root partition?
5) And then copy across all the files from the backup into the / root partition?
I ask these questions because of the (very nice) way linux OS is built entirely from packages... Am I being too complicated? (By comparison, I can see it is easy to recover user data.)If, instead, I simply recovered the backup straight onto the updated root filesystem, I wonder what it would look like if I then tried to verify it with "rpm -Va", for example? Surely, all the packages would fail the verification, because it would think it has a later version of each package from the update, but the actual files would have been overwritten by the earlier version from the backup?

I'm gonna buy a 1.5 TB HDD to put there backups, videos, and stuff like that, and i was wondering what Filesystem should i put there considering that it will be used for backups (mostly) and I must count with that drive in case of something going wrong.

in preparation for the update to Slackware64 13.1 I did a complete backup of my system with dd.
I used the Slackware 13.0 (not 64 bit) DVD to boot and executed the command:
# dd if=/dev/sda of=/dev/sdb
The command finished without any errors as expected. First I tried to boot the destination hard disk to check if the backup was successful and I can start with updating the source disk to 13.1. But at boot time I got the message that the last file system check is 197 day ago, the file system check started automatically and found errors which it could not correct. At this point I thought it was maybe a copy or a hard disk error and tried to boot the source disk. But the behaviour was exactly the same on the source disk. With the source disk I followed then the recommendation, logged in with root password and executed the recommended command which was something like e2fsck -v -h /dev/sda1. Then the system did a file system check and scrolled a lot of numbers over the screen. After a while it reported that it's ready and the system needs a restart.
I switched off and on again. Then the system bootet as usual, and seems to run okay at the moment. But now I'm unsure if really everything is okay.
What I'm confused of is, why the system reported that the last file system check was 197 days ago and why this was just after the dd backup. Shouldn't the automatic file system check at boot time run more often as every 197 days or mounts? I didn't change any default settings (as far as I know). The file system of the root partition is ext4 and my computer normally is switched on and off once every day.
My question now is, if this behaviour can have something to do with the dd backup.
Is my system after the file system check okay again, or should I expect further problems?

Using tar is it possible to backup different types of file system e.g.ext3, ufs, or any other file system. I know using dump it is not possible because it is reading through raw device. Then what about tar? Where I get more info about this? Means suppose I want to backup files from different file systems using tar then is it possible?

I am trying to mount a file image, like this
mount -o loop /tmp/apps.img /media/apps
But I get the following:
mount: you must specify the filesystem type
I try ext3:
mount -o loop /tmp/apps.img /media/apps -t ext3
dmesg says:
error: can't find ext3 filesystem on dev loop6.
I've also tried ext2, vfat etc. How can I detect the filesystem type of apps.img?

I've had a look at some similar threads but as I'm very new to linux they're already a bit technical for me. Sorry, this calls for someone with patience. I gather from other threads that disconnecting an external drive without unmounting is a no-no, and this seems to be the likely cause. Now the disk is read only and I'm unable to change any settings through the usual control panel on ubuntu. I'm just not familiar with the terminal instructions. I tried to cut and past a few command lines from other threads but I got some warnings that proceding could damage data. Like this one: WARNING! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage.

I've been running Fedora 12 for a few weeks on a laptop, and was just starting to get things the way I like it ... and last night as I was trying to unlock the screen using the fingerprint reader (which had always previously worked) the system became unresponsive and there was nothing I could do but push the power button. Now it will not boot up, I get one cursor flash when it's at the grub stage and then the screen goes dark, there is no hard disk activity. He's dead jim.
I'm a bit gutted and would like to recover this system if I can, rather than install something else over the top. I booted using an ubuntu live cd and mounted the lvm, and got into the /var/log/messages. The last entries in there before it crashed and burned are as follows:

What am I doing wrong here in compiling 1.2.6! I am following this link: url
What is wrong with this?? I DL'd wxGTK-2.4.2.tar.bz2 from url, which got me this:
~$ tar -xvjf wxGTK-2.4.2.tar.bz2
tar: wxGTK-2.4.2.tar.bz2: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
tar: Child returned status 2
tar: Exiting with failure status due to previous errors
What did I do wrong?? And bunzip2 gives this:
~$ bunzip2 wxGTK-2.4.2.tar.bz2 bunzip2: Can't open input file wxGTK-2.4.2.tar.bz2: No such file or directory.
BTW, the file is on the Desktop. The reason for all this work is that 1.3.12beta no longer has the mixer toolbar built-in that allowed easy to choose devices like "line-in","mic", etc. I have 1.2.6 installed on an XP machine and it is great.

I'm just setting up a partition on a seperate HDD in my system. I plan to use the partition to backup the important files on my main HDD (to guard against HD crash).
The question I have is about where would be the typical location to auto mount this partition? Which would it be normal to go for:
1. /backup/
2. /media/backup/
3. /mnt/backup/
4. /home/chris/backup/

I am very new to linux, and I have a question regarding the filesystem check (fsck). The power recently went out and when I tried to restart linux the following error appears:
*/dev/sda1 contains file system w/errors, check forced it then goes on to say..
*An error occured during the file system check. Dropping you to a shell; the system will reboot when you leave the shell. Give root password for maintenance (or type Control-D to continue) I wasn't sure what to do, but checked some other online forums and they suggested running fsck manually - so I typed in the root password - and used the command, "fsck -A -V ; echo == $? ==" it then gave the following message
*WARNING!!! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage
*Would you like to continue (y/n)
Again, I wasn't sure what to do so i just checked no. I then manually turned off the computer and was prompted at the beginning to press Alt-3. I was brought to another screen and it informed me one of the drives was degraded and suggested rebuilding the array. I tried doing this, but it still brings me back to the original error of, "/dev/sda1 contains file system w/errors, check forced," and the process continues.
Also, when I tried to rebuild the array, I didn't backup any of the data on our home directory before doing this (which was probably a big mistake). After being prompted to type the root password, I was able to give the ls command and look at all the directories...the home directory where our data was stored was empty and I am afraid I may have lost some information. Is there a possibility that data was lost when I was trying to rebuild using the old drives?

We just migrated from Solaris to RHEL 5 this weekend. All our printers are working fine using CUPS except for one model. Zebra QL 320+ mobile/wireless printers. We can ping the IP and printer-id from the server fine. But when you try to print a job to it from the command line or a test page from the CUPS interface, the printer status in CUPS shows ""recoverable: Network host 'xx.xx.x.xxx' is busy".This is a major issue for us as we have lots of these printers. All other printers - all Ethernet are fine; including Ethernet Zebra printers.

When I try to boot to OpenSUSE I get the following error during boot-up: unknown filesystem type 'reiserfs' could not mount root filesystem - exiting to /bin/sh$
This only started happening quite recently - before this I could boot to Linux quite happily.

I have a following problem: Recently my drive with Ubuntu 9.4 has mysteriously stopped working, i.e. when I switch the computer on it informs me that GRUB didn't find the filesystem. Well, I suppose it happens.
First, I though it was due to the drive dying, but I popped it in an external enclosure and HDTune told me the drive was fine. Wanting to recover the files on the drive before reinstalling I first tried to mount it in said external enclosure under Windows (I have Win Ext2 driver installed which used to work just fine). This time, however, drive gets assigned a letter but upon opening it Windows popped up an error saying that the drive was not formatted and whether I would like to format it then.
Unfazed by this streak of failures I tried to mount it under Linux but, alas, to no avail. I might have tried every single -t operator under mount command but it still won't budge and let me mount.

using Back In Time to backup my home directory to a second hdd that is mounted at /media/backupThe trouble is, I can do this using Back In Time (Root), but not using Back In Time without the root option. This is definitely a permissions issue - it can't write to the folder, but when I checked by right clicking on the backup directory and looking at the permission tab, it said I was the owner

After I spent some time discovering The BIG BANG of Universe and The Meaning of Life :
I managed somehow to create a script to make some backup of files on server and TAR it and then FTP the archive to another location FTP server and then emails result.
It also measures time needed to complete it and deletes archive older than XX days (set in find -mtime +20) and makes incremental backup every weekday and FULL on Sundays (which suits me bcoz no heavy load).
Files for TAR to include and exclude are in txt files listed each line separate name:
file: including.txt:

This script simply deletes files older than a certain age (in this case 7 days) from a certain location; I use it to purge old backups nightly, and it works as expected:
# delete backups older than 7 days
find /mnt/backup/* -mtime +7 -exec rm -Rf {} ;
The problem is, every morning I get an email with an error message something like this:
find: `/mnt/backup/subfolder': No such file or directory

I have a scheduled backup to run on our server at work and since the 7/12/09 it has be making 592k files instead of 10Mb files, In mysql-admin (the GUI tool) I have a stored connection for the user 'backup', the user has select and lock rights on the databases being backed up. I have a backup profile called 'backup_regular' and in the third tab along its scheduled to backup at 2 in the morning every week day. If I look at one of the small backup files generated I see the following:
Code:
-- MySQL Administrator dump 1.4
--
-- ------------------------------------------------------
-- Server version`
[code]....
It seems that MySQL can open and write to the file fine, it just can't dump

I've tried to google but not much luck. What I would like to do is have anumber of folders on my desktop and their contents, replicated/duplicated into another folder on the same PC in real time. So for example, if I were to change an OpenOffice document in a specific folder on my Desktop it would be replicated/duplicated in real time. If I had three folders on my Desktop A, B and C they would also appear/be backed up (in real time) in a folder called /home/backup. Can this be done?
