Subject Re: Secondary Storage explained

Let me correct a little bit of what Rafael has said. In the snapshots
folder itself, the number dirs are account IDs.

root@gcx-bom-cloudstack:/mnt/secondary/snapshots# ls -l
total 6
drwxr-xr-x  8 nobody nogroup  8 Jul 13 12:07 10
drwxr-xr-x 18 nobody nogroup 18 Aug  3  2016 2
drwxr-xr-x 11 nobody nogroup 11 Jul 15 20:34 22
drwxr-xr-x  3 nobody nogroup  3 Sep  3  2016 31

Above shows that snapshots  for these account IDs. (Using account ID you
can find domains)

Whatever is inside these snapshot dir, are volume IDs. Here is example for
account ID 22

root@gcx-bom-cloudstack:/mnt/secondary/snapshots# ls -lrth 22
total 14K
drwxr-xr-x 2 nobody nogroup 2 Sep  1  2016 1004
drwxr-xr-x 2 nobody nogroup 2 Nov 27  2016 1114
drwxr-xr-x 2 nobody nogroup 2 Dec  7  2016 1052
drwxr-xr-x 2 nobody nogroup 2 Dec 19  2016 1016
drwxr-xr-x 2 nobody nogroup 2 Dec 26  2016 1003
drwxr-xr-x 2 nobody nogroup 2 Sep 10 00:39 1111
drwxr-xr-x 2 nobody nogroup 2 Sep 10 03:09 1202
drwxr-xr-x 2 nobody nogroup 5 Sep 23 17:33 1002
drwxr-xr-x 2 nobody nogroup 5 Sep 23 20:33 1015

So account 22 snapshots is happening (or happened in past) for volume IDs
mention above (dir names). Each of this folder contains 1 or more vhd files
that are created by snapshots.
