Filesystem Backup always wants to use TAR format...

Submitted by Locutus on Tue, 05/31/2011 - 06:06

...even if I set "Always use TAR format for backups?" in the module config to "No", and leave the checkbox "Add new backup: In TAR format" unchecked.

Closed (fixed)

Are you backing up a local filesystem, or an NFS mount? For remote filesystems, only TAR format backups are possible ..

I tested it with /etc. :)

On the "Add New Backup" screen, it says "Backup format: Unix TAR" despite I left that checkbox unchecked on the screen before.

What filesystem type are you using on the filesystem that contains / ?

If it is ext3 or ext4, does your system have the dump command installed?

Okay, I get it.

The one I tested was ext4. I just installed "dump" and tried an ext2:

Backup format   EXT2 filesystem dump

So that solves that. A little hint in the documentation might be in order, that "dump" is required and the FS must be ext2 or ext3. :) I was silently assuming that you use rsync in case I turn off "TAR format".

Ok, I see the bug now .. that module doesn't know about the ext4 format, so refuses to use dump and always falls back to tar . I will fix this in the next Webmin release ..

Okidoki. Though you might want to be careful: Google finds me reports by users stating that ext4 dumps get corrupted. I can do tests on my Ubuntu if you wish.
