When I inserted a 1 TB-drive into my new Qnap NAS, it removed my partition on that drive without notifying me first.Is there a way to retrieve the actual locations of the backup superblocks, or any other ways to guess their locations?
View 11 RepliesI know there are many threads about recovering damaged superblocks. I've spent 3 evenings reading them and trying what they suggest. Invariably the commands do nothing except to report bad or missing superblocks. I've removed the physical disk from the machine and am working with a dd image file (/mnt/image). I can mount what used to be hdc1 and read its files with no problem. I'm trying to recover partions hdc6 and hdc7.$ mmls /mnt/image -b

I have an image of an ext3 file system done with dd. I know that the file system is corrupted but I want to try to recover some files. Whatever I dd it again to the original partition or assign the dd image to a loop device, that's what happens:
- dumpe2fs -h gives me a valid ext3 superblock.
- as I try to mount the device read only, it fails with a bad magic number error.
- executing dumpe2fs -h again gives bad magic number error.
- trying debugfs or fsck with backup superblocks fails the same way.
For me it seems that in spite of mounting the device as read-only, mount command do something wrong with the superblock as before the mount the superblock is correct and it's there.

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

View 12 Replies View RelatedAfter 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`

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?

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:

2. /media/backup/
3. /mnt/backup/
4. /home/chris/backup/

Does anyone know of any decent enterprise level backup solutions for Linux? I need to backup a few servers and a bunch of desktops onto one backup server. Using rsync/tar.gz won't cut it. I need like bi-monthly full HDD backups, and things such as that, with a nice GUI interface to add/remove systems from the backup list. I need basically something similar to CommVault or Veritas. Veritas I've used before but it has its issues, such as leaving 30GB cache files. CommVault, I have no idea how much it is, and if it supports backing up to a hard drive rather than tape.

View 2 Replies View RelatedI'm trying to backup a NAS from remote. The only options it has are FTP, NFS and CIFS. The only encryption method it has is explicit ftp encryption (old school). I know lot's of ways to backup if I open the firewall to allow SMB access, but I know that you can't encrypt in transit with it. I don't know much about NFS and the NAS has virtually no options for it, so I'm guessing encryption isn't supported on it. This leads me to FTP with explicit encryption. I've done a bit of research on software that can backup over ftp and have not found many. Furthermore, I haven't found any that will work with explicit encryption. I had a bit of success using lftp but then realized it's an all or nothing sort of thing (I don't want to backup 1tb+ of movies that I can just rip again if I lose them due to space constraints).
View 1 Replies View RelatedI know how to backup a filesystem with tar and restore it later, but i'd like to know how to do that with a remote system. I'm really terrible at all command piping stuff and i can't simply adapt the tutorials to my needs. What i'd like to do is to login as root@remotemachine and issue a tar command on the entire / directory that would save the resulting archive to my local machine. And then i'd like to do it backwards (restore). I've seen some commands on the net ... something like:
ssh -something root@remotemachine "cd /; tar -cpf - ." | tar -xf -
I don't remember it exactly but i now that this command copied the filesystem over to my computer and i don't know how to change it to create an archive instead.

I am running Ubuntu 9.10 Gnome I have twin hard drives in my system. I use rsync to automatically back up my home user directory on the first drive to the second drive everyday. This has been working well for almost a year. My first drive is 85% full, but suddenly, my second drive is 100% full...in fact, rsync errored out having filled the second drive.
I erased the second drive, and using nautilus I copied the section of my first drive that I back up to the second drive (minus a few large files). When it was finished, the second drive was 99% full. As near as I can tell, my backup has about 30 GB of extra information, but I have been unable to determine what the extra data is! I am no longer able to do backups until this gets resolved. Does anyone have any idea what this could be, and how to discover where it is coming from? So that it can be rectified?
I thought maybe some link had somehow gotten created and my backups are following the link and copying the same info twice or something, but I haven't been able to figure out how to list all my links in my file structure on some kind of search.
