Backup Cluster File System

Hi all,

We have four (04) servers running RHEL 7, they are all part of the same Veritas Cluster. They share six (06) File systems (CFS), my question is how can we backup those file systems using the available servers which means, if the four (04) servers were up, we will spread the backup between them all, if a server is down, the backup will be spread between the remaining three (03) servers and so on.

The setup we are looking for does not need any manual intervention.

Thanks in advance.
