Awesome idea!
Now Geo-rep can be used to take daily/monthly backup. With Gluster
3.7.9, we can run Geo-replication whenever required instead of running
all the time.
http://review.gluster.org/13510 (geo-rep: Script to Schedule
Geo-replication)
Full Backup:
------------
1. Create Geo-rep session.
2. Run Schedule Geo-rep script
3. Take Gluster Volume Snapshot at Slave side.
Incremental(Daily):
-------------------
1. Run Schedule Geo-rep script
2. Take Gluster Volume Snapshot at Slave side
Note: Delete old snapshots regularly.
Restore:
--------
Depending on the snapshot you want to recover, Clone the snapshot to
create new Volume and then establish Geo-replication from cloned
Volume to new volume where ever required.
If we need to restore any specific file/directory then just mount the
snapshot and copy data to required location.

Subject: [Gluster-devel] Using geo-replication as backup solution using gluster volume snapshot!
Hi All,
Here is the idea, we can use geo-replication as backup solution using gluster
volume
snapshots on slave side. One of the drawbacks of geo-replication is that it's
a
continuous asynchronous replication and would not help in getting the last
week's or
yesterday's data. So if we use gluster snapshots at the slave end, we can use
the
snapshots to get the last week's or yesterday's data making it a candidate
for a
backup solution. The limitation is that the snapshots at the slave end can't
be
restored as it will break the running geo-replication. It could be mounted
and
we have access to data when the snapshots are taken. It's just a naive idea.
Any suggestions and use cases are worth discussing:)
Thanks and Regards,
Kotresh H R
