restore files from a backup job

Triggering restore is implemented using Extended Attributes. This prevents, that a normal read access triggers a restore job. To trigger a restore, set the extended attribute user.bareos.do of a file or directory to restore.

Note:

• the mount parameter restoreclient is required for this operation. Otherwise you get a EPERM error.

• the mount parameter restorejob is required, if you have more then one restore job defined.

Example for restoring all files of a full backup job:

# cd /mnt/clients/client1-fd/backups/jobid\=887_level\=F_status\=T/data/
# getfattr -d .
user.bareos.do
user.bareos.do_options="mark | restore"
user.bareos.restored="no"
user.bareos.restorepath="/var/cache/bareosfs//jobid=887"
# setfattr -n user.bareos.do -v restore .
# getfattr -d .
user.bareos.do="restore"
user.bareos.do_options="mark | restore"
user.bareos.restore_job_id="913"
user.bareos.restored="yes"
user.bareos.restorepath="//var/cache/bareosfs//jobid=887"

Files are now readable and links show there destination.

Instead of restoring all files and directories from the backup, you can set the “restore” value on individual files. Each set will trigger a separate restore job.

Alternative: mount command

The baroes-fuse packages do also contain the mount.bareosfs link. Using this, the normal mount command can be used:

mount -t bareosfs -o address=localhost,password=secret,logfile=/var/log/bareosfs.log fuse /mnt
