Proxmox backup behaviour

[casalicomputers]

Hello,
I have the following scenario: a backup task of 5 vms is running at 09:00 pm and, for simplicity, let's assume that each backup is 10 Gb. The backup storage is set to maintain 5 copies, and at the current time there are already 5 copies, so at the next backup the oldest should be deleted.

When old backups are going to be deleted?
At the end of each single backup task or at the end of the whole chain?

Thanks

When old backups are going to be deleted?

After a new successful backup.

At the end of each single backup task or at the end of the whole chain?

After each VM is backed up.
