Restore not possible because /var not mounted

Post by grufo »

Veeam Case ID: 04713453

I can not restore from my backup because /var does not get mounted from backup.

We use to mount our web folders for chroot access into /home/chroot directory with the following command:
mount --bind /var/www/vhosts/test /home/chroot/chroot-test-user/test/

On the host where /var is not mounted form backup this seems to be the problem.

When we mount the backup the "mount" command show the following:

Code: Select all

/dev/loop9 on /mnt/backup type ext4 (rw,relatime)
/dev/loop1 on /mnt/backup/srv type ext4 (rw,relatime)
/dev/loop11 on /mnt/backup/usr type ext4 (rw,relatime)
/dev/loop13 on /mnt/backup/tmp type ext4 (rw,relatime)
/dev/loop7 on /mnt/backup/boot type ext2 (rw,relatime)
/dev/loop10 on /mnt/backup/home type ext4 (rw,relatime)
/dev/loop14 on /mnt/backup/sda9 type ext4 (rw,relatime)
/dev/loop0 on /mnt/backup/disk1 type ext4 (rw,relatime)
/dev/loop3 on /mnt/backup/disk2 type ext4 (rw,relatime)
/dev/loop2 on /mnt/backup/disk3 type ext4 (rw,relatime)
/dev/loop4 on /mnt/backup/backup.cloud type ext4 (rw,relatime)
/dev/loop12 on /mnt/backup/home/chroot/chroot-test-user/test type ext4 (rw,relatime)
The /var volume has the uuid: 9b8da5f8-368b-4db7-b867-b449b54f9de7

The Manager.log files has an entry with that uuid:

Code: Select all

I think /dev/loop5, /dev/loop6 and /dev/loop8 are missing.

Anybody else with that problem?
Really bad about the problem is that you only discover it when you want to restore data! :-)

Re: Restore not possible because /var not mounted

Post by grufo »

If I unmount those "mount --bind" directories and start a new backup job, the restore is ok afterwards!

Backup with "mount --bind" active looks like that:

Code: Select all

root@server:/var/log/veeam# ls /mnt/backup/var/
cache  lib  lock  log  run  spool
Backup without "mount --bind" looks like that:

Code: Select all

root@server:/var/log/veeam# ls /mnt/backup/var/
backups  cache  lib  local  lock  log  lost+found  mail  opt  run  spool  tmp  www
So the workaround would be to create a pre/post script to unmount and remount the directories.
But the Veeam Agent version 5.0.0.4318 has definitely a problem with "mount --bind"!
