Hello.
At a site I manage, we've got Bacula backing up a bunch of clients to a
NAS SD daily.
Occasionally (once a week ATM) we want to move the backed up data to an
external HD for more resilience.
I'm asking for suggestion on how to better do this.
Currently, I'm using vchanger and Copy jobs to achieve this, selecting
the most recent Full+Diff for every client (through an SQL query): this
works, but uses more space than needed (of course all modified files
being on both the Full and the Diff volume), so often the disk gets full.
I thought about VirtualFull to consolidate the data, but AFAICT there's
no way to tell Bacula to then ignore the new volume (like copy does), so
in case of a restore I would have to plug in the disk while I have all
the needed data on the NAS.
I could try a restore to the disk, but I would need some on the fly
compression system and I don't think this could be easily automated.
Any other idea (apart from buying bigger disks)?
bye & Thanks
av.
