Backup settings

Excuse me, I want to backup "mode: snapshot" every 30 minutes and keep 3 copies every day.
At the same time, backup "Mode: Stop" every 6 hours and keep 1 copy every day.
How to set up schedule

With VZDump or PBS?

You need two backup storages for that and two backup jobs.

For retentions see the prune simulator: https://pbs.proxmox.com/docs/prune-simulator/

Hello, I have set up two backup jobs, one is a snapshot backup (keep the latest), and the other is a shutdown backup (keep the latest).
It results in PBS only being either a snapshot backup or an outage backup, not both.

I would recommend that you use a datastore and work with namespaces there. Then you still have to add both namespaces in PVE (like @Dunuin said). On the PVE site you say that you want to keep all backups.

In the PBS you then set your prune jobs according to your requirements under Datastore -> "YOUR DATASTORE" -> "Prune & GC". Don't forget to take the namespaces into account in the prune job.

Yes, thats how I manage my snapshot-/stop-mode backups and it works well. Just keep in mind that using multiple backup jobs to different namespaces will drop the dirty-bitmapping so backups will take longer. But on the other hand doing a stop-mode backup will drop the dirty-bitmap anyway.

Thanks to the two seniors for their guidance, the settings have been completed.
