I have 2 servers running gluster. Each server has 1 brick each which is part of a replica-volume. Data is getting replicated onto both the bricks.
* How to backup data from the bricks. ?? * How to backup all gluster configurations. ?? Why I ask this is, we are using this deployment for saving user files. The application allots 1GB quota for each user as his personal workspace. Ofcourse, we would want to backup the data. !!! Thanks & Regards, Bobby Jacob P SAVE TREES.

Why would you not be able to backup anything? Could you elaborate, what you mean? What do you want to do actually? Maybe we are talking about different things... tamas On 09/02/2013 09:54 AM, Bobby Jacob wrote: So is it assumed within the community that we can setup a gluster volume, but we cannot backup/restore anything. ?

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. tamas ui.: I use dirvish (rsync based backup solution) and it works fine, though cluster side snapshotting feature would help a lot. http://www.gluster.org/community/documentation/index.php/Features/snapshot Yes, I know about that, unfortunately it's not ready yet: 3 Current status No support availabe for snap'ing a glusterfs volume tamas
