Hello list!
I have some kind of problem when trying to restore files I've backed up
with bacula.
Please let me walk you trough my setup first:
For my Bacula installation I defined three Pools:
- Pool_FullBackup
- Pool_DiffBackup
- Pool_IncBackup
My DIR Job Definition looks like this:
--------------------------------------------------------------------
Job {
Name = "Job_hexbmc02"
Client = "hexbmc02-fd"
DifferentialBackupPool = "Pool_DiffBackup"
Fileset = "FileSet_RHEL-FullBackup"
FullBackupPool = "Pool_FullBackup"
IncrementalBackupPool = "Pool_IncBackup"
JobDefs = "JD_heDefault"
Pool = "Pool_IncBackup"
Schedule = "FullDiffInc-DailyBackup_Evening_Schedule"
Storage = "heBacula-sd-AC-FullBackup"
WriteBootstrap = "/opt/bacula/working/%c_%n.bsr"
}
--------------------------------------------------------------------
A DIR Pool definition
--------------------------------------------------------------------
Pool {
Name = "Pool_FullBackup"
ActionOnPurge = Truncate
FileRetention = 6912000
JobRetention = 6912000
LabelFormat =
"FullBackup__${Client}__${JobId}__${Year}-${Month:p/2/0/r}-${Day:p/2/0/r}T${Hour:p/2/0/r}.${Minute:p/2/0/r}.${Second:p/2/0/r}"
MaximumVolumeBytes = 4194304000
MaximumVolumeJobs = 1
PoolType = "Backup"
Recycle = no
Storage = "heBacula-sd-AC-FullBackup"
}
--------------------------------------------------------------------
A SD Backup device:
--------------------------------------------------------------------
Device {
Name = AC-FullBackup-Dev01
Media Type = MT-heBacula-sd
Archive Device = /srv/bacula-sd/AC-FullBackup
LabelMedia = yes; # lets Bacula label unlabeled media
Random Access = Yes;
AutomaticMount = yes; # when device opened, read it
RemovableMedia = no;
AlwaysOpen = no;
Maximum Concurrent Jobs = 5
}
--------------------------------------------------------------------
Now, backups seem to run as expected:
* all Fullbackups labeled FullBackup__${Client}_[...] end up in the
/srv/bacula-sd/AC-FullBackup directory.
* all Diffbackups labeled DiffBackup__${Client}_[...] end up in the
/srv/bacula-sd/AC-DiffBackup directory.
* all Incbackups labeled IncBackup__${Client}_[...] end up in the
/srv/bacula-sd/AC-IncBackup directory.
Yesterday I needed to restore some files. I used bconsole -> restore ->
5: Select the most recent backup for a client -> <SELECT CLIENT> ->
<SELECT FILESET>
I selected some files to restore and started the restore.
Now, what happened is the following:

-----------------------------------------------------------------------------------------------------------------------------
As far as I read this information, the following has happened:
1) Backup looked up the required Full Backup and started restore (or
searched this volume for the files to be restored) -> OK
2) Bacula reached the end of this volume and tried to "mount" the next
volume containing data for this client -> OK
3) Bacula tried to mount a DiffBackup volume into a FullBackup "device":
Could not
open(/srv/bacula-sd/AC-FullBackup/DiffBackup__hexbmc02-fd__1029__2018-02-18T20.00.46,OPEN_READ_ONLY,0640)
This is wrong, since the DiffBackup volumes are in the AC-DiffBackup directory.
Now, I was able to complete the restore by
sym-linking the file from AC-DiffBackup to AC-FullBackup.
But anyway this seems to be wrong. Unfortunately I have no idea how to tell the restore
command to use the "correct" Autochanger.
Moreover, I would expect that the Volume Information and the Device information
would somehow correlate in the database?
Any help / pointer into the right direction in order to solve this (and maybe
get a better understanding about Bacula) would be greatly appreciated!
Thanks in advance,
Thorsten
