Hi,

I have a number of servers that I backup to a bareos server with plenty of disk storage.
I get this error (after s number of days of no problems with the jobs): 

bareos-sd JobId 181: Job server3-var-backup.2021-05-10_23.00.01_03 is waiting. Cannot find any appendable volumes.
Please use the "label" command to create a new Volume for:
Storage: "Server3Storage" (/data1/server3)
Pool: Incremental
Media type: File

I had this error before, and then I increased the Maximum Volumes to 1000 in the files /etc/bareos/bareos-dir.d/pool/  (Incremental.conf, Full.conf, .....)

What is the correct way to configure this so I don't get this problem anymore? I have more diskspace on the backup server than all my other servers combined, so storage on the backup server should not be a problem for the near or medium far future.

best regards,
Andy

This means, you ran out of *volumes* (not necessarily out of *disk
space*).

Are you doing a Full-Differential-Incremental strategy or
AlwaysIncremental? In the second case, I cannot help you (as I do not use
that strategy for my backups). In the first case: Do you have a
recent-enough Full/Differential backup? If you have too few of them, you
will accumulate quite a number of incrementals in-between (though, 1000
seems plenty even in this case - or are you backing up hundrets of
servers?).

In either case, also have a look at your Volume Retention and possibly set
AutoPrune in your Pool configurations.

Hi Erich,

to answer your question: I use the always-incremental strategy, though I'm beginning to question if I shouldn't change this.
I've increased the number of volumes, so this is giving me some time to look for a permanent solution.

best regards,
Andy

Nothing wrong with AlwaysIncremental - just, that I have 0 experience with
it.

You won't see, if any other change is successful, when you keep increasing
the number of volumes: bareos will only start recycling old volumes, if it
runs out of unused volumes. (though, I can understand, that one wants to
increase the number of volumes to make it "just work for now" again)
