Hi,

 

for my company I’ve set up a bacula-server which backups several clients to an NFS.

The NFS is mounted on the Bacula-server and has 500GBs space.

 

I have to back up about 50 clients.

I do full backups on Saturdays and incremental backups every other day.

I set the file and job retention to 14 days for every client, AutoPrune is on.

Every client writes into its own pool on the NFS. Every pool can contain a maximum of 20 volumes and I use every volume only once.

The also get recycled and autopruned.

The volume retention period is set to 14 days.

 

So all retention periods are 14 days.

 

With this configuration, the 500GB space are usually sufficient to store 3 full backups and several incremental backups of all the hosts.

 

Now my problem is the following:

 

If I make full backups from all the clients, on my own outside of the schedule, the 500GBs are full, but Bacula doesn’t recycle the older volumes, because the retention period and max. volumes limit is not reached.

 

So what are my options?

 

-       Increase the storage (possible, but only a workaround?)

-       Manually delete the files that are older than 14 days on the NFS (what I’m currently doing)

-       ???

 

 

Thanks for your help in advance!

 

 

Cheers

 

Sebastian
