I'm in doubt about restore syntax:
Usage: collie vdi restore [-s snapshot] [-a address] [-p port] [-h]
<vdiname> <backup>

In this example, I kept the vdi (id 0) and the first snapshot.
1)To restore the 4th snapshot is this the correct syntax?:

collie vdi restore -s 1 squeeze < squeeze_s4_s1.img

2) the images created by vdi backup, are already compressed?
I noticed that the images size is smaller than the amount data I've
been writing between snapshots.

Thank you.
