Move older backup to different datastore

[titouan]

Hello, is it possible to define a retention policy that spreads across multiple datastores?
What we are looking to do is to keep x days of backups on our main datastore which is SSD backed and keep x monthly backups on a secondary datastore with HDDs.
Is it possible to implement such a strategy with PBS and if so how would we do it?

Hi,
you can define a local sync job from the fast/short term datastore to the slower/long term datastore and use prune jobs which keep snapshots according to your needs.

Ok, thanks Chris! That is what I had in mind.
I'll try to configure this and get back to you if I'm having trouble with the setup.

Something I just thought of, can I filter which backup to sync to the long-term datastore or will I have to copy all backups from the fast storage and then prune the ones I do not need?

You can filter them e.g. by backup group filters and transfer last according to your needs. No need to sync all snapshots.
