Re: Backup bricks?

[Aravinda <avishwan@xxxxxxxxxx>]

Gluster Geo-replication can be used to replicate the data from one
Volume to other remote Volume. Geo-rep has intelligence in detecting
Changes happened in Volume without Crawling and syncing efficiently
using Rsync.

Geo-rep is continuous event, can be scheduled to run using stop/start
commands. For example, if Backup is required to run in night, then run
Geo-rep Start command in night and run Geo-rep stop command in the
morning.

Geo-rep is not exactly brick-brick copy, Slave Volume can be different
than Master Volume(1x2 Volume in Master and 1 brick in Slave).

Geo-replication is not a true Backup utility, you can't restore the Volume
to a particular date's state like we can do with other backup tools.

Let us know if you have any questions.

I have a 1 x 2 = 2 volume geo-replicated to a single-brick volume in another physical site, where I would like to set up a backup.

I could setup a backup on a mount of the volume, but a quick test shows it is slow in this setup (presumably because there are loads of small files on there).

Instead I thought I could maybe backup the filesystem where the brick is (or rather a snapshot of the thin logical volume).  My understanding is that all the files will be in there, and readable, so it seems to me it would be fine to back things up from there.

Is that right, or am I missing something here?

Note the .glusterfs directory would also be backed up too, although I'm not sure whether that would be of any use in a backup.

More generally is there a recommended way to setup backups?

Thanks,
Thibault.
