With yet another gluster disk failure / gluster collapse, it appears I lost the "main" backing image for one of my vm servers.  I have snapshots still in tact (or at least, appear to be), but the main image is gone.

The main server process stores a backup at regular intervals in its disk, and that would have been changed data, so it would be in the snapshot rather than the base image.  Is there any way to recover this one .tar.gz file from the snapshot with the missing main image?  This is a backup of dynamic data, and without it, I will have lost several customers data, some of which cannot be recreated/regenerated.

it also appears that my backup (gluster geo-replication) did not work (had crashed a while ago, and has a very old backup of this image).
