That link you sent was good, I am looking in to it, it may provide a large
amount of help.
One last thing.... :-)
Now imagine this:
create disk0
Activity on disk0
Take a snapshot
disk0 -> disk0_snap0
Activity on disk0
take a snapshot
disk0 -> disk0_snap1
(We will now use the differential between snap1 and snap0 to represent
what needs to be backed up from snap1)
This leaves us with something that looks like this:
disk0 --> disk0_snap0
-> disk0_snap1
Will we need to remap the parentage of disk0_snap0 so it looks something
like this?
disk0 -> disk0_snap1 -> disk0_snap0
(Is this possible with dmsetup?)
Or could we have many (order of hundreds or thousands) of snaps directly
on disk0 and not impact performance?
