<pre> <o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>What would be the various options to backup gluster volumes. The<o:p></o:p></pre>
<pre>bricks are created with xfs filesystems. I’ve gone through the<o:p></o:p></pre>
<pre>concepts of xfsdump concept. Can we schedule daily incremental backups<o:p></o:p></pre>
<pre>of the gluster volume or bricks. ??<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre> <o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>What about restoring the bricks or volumes. ?<o:p></o:p></pre>
<pre><o:p> </o:p></pre>

<pre><o:p> </o:p></pre>
<pre>I wouldn't make backups under glusterfs. In theory it should work, but<o:p></o:p></pre>
<pre>there are too many critical points in the system.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>For example you need to stop every transaction (in case of VMs, then all<o:p></o:p></pre>
<pre>of them) to make consistent snapshots.<o:p></o:p></pre>
<pre>If you have multiple bricks, all of them has to be snapshotted at the<o:p></o:p></pre>
<pre>same time....etc.<o:p></o:p></pre>
<pre>In addition restoring would be nightmare.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>IMHO, it's a crazy idea.<o:p></o:p></pre>

<pre>tamas<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>ui.: I use dirvish (rsync based backup solution) and it works fine,<o:p></o:p></pre>
<pre>though cluster side snapshotting feature would help a lot.<o:p></o:p></pre>
