Hi,
What would be the various options to backup gluster volumes. The
bricks are created with xfs filesystems. I’ve gone through the
concepts of xfsdump concept. Can we schedule daily incremental backups
of the gluster volume or bricks. ??
What about restoring the bricks or volumes. ?
I wouldn't make backups under glusterfs. In theory it should work, but
there are too many critical points in the system.
For example you need to stop every transaction (in case of VMs, then all
of them) to make consistent snapshots.
If you have multiple bricks, all of them has to be snapshotted at the
same time....etc.
In addition restoring would be nightmare.
IMHO, it's a crazy idea.

ui.: I use dirvish (rsync based backup solution) and it works fine,
though cluster side snapshotting feature would help a lot.

Yes, I know about that, unfortunately it's not ready yet:
