Hi, Thanks for your help. > I assume that you are speaking of rbd only Yes, as we just started studying Ceph, we only aware of backup of RBD. Will there be other areas that need backup?

Besides, can we somehow "mount" snapshot of nth day to get the backup of particular file ? sorry that we're still based on traditional SAN snapshot concepts. Sorry to bother, and thanks a lot.

Besides using incremental snapshots with RDB to backup data on one Ceph cluster to another running Ceph cluster, or using backup tools like backy2, will there be any recommended way to backup Ceph data ? Someone here suggested taking snapshot of RDB daily and keeps 30 days to replace backup.
