I get the following error if i run pbs backup client too fast after another

creating backup of directory /boot
Starting backup: host/server1/2020-07-29T22:39:44Z
Client name: server1
Starting protocol: 2020-07-29T22:39:44+00:00
Error: backup timestamp is older than last backup.
Even if the backup storage is empty e.g there is no existing backup of the directory.

If i add a sleep of 1 second between the calls it does not happen. But why ?

The backup timestamps are currently tracked in one-second granularity. This means that backups to the same backup group (i.e. a workaround is to use different backup groups) cannot happen within the same second.

This is something we are working on improving atm :)

How can i change the backup group, could not find anything in the documentation ?

It seems to be automatically set to the hostname.

the --backup-id parameter allows you to set it for host-type backups
