We have allways been a veeam customer since vwmare. I have moved over to the beta version of veeam for our windows servers.
XOA is only backing up our linux servers. So half the workload was removed from backups.
Different use cases: Ceph is better with more hosts (at least 6 or 7 minimum) while XOSTOR is better between 3 to 7/8.
We might have better Ceph support in the future for large clusters.
