Hi,
Is there a built in way to keep snapshots on the same node?
Namely, on each (e.g., of the two) nodes
 Allocate extra space in advance 
 Configure DRBD to 
 /dev/drbd0
  /dev/sda1 - active partition
  /dev/sda0 - dedicated for keeping one snapshot
 
Take snapshot should be fast - much faster than dd
Allow Reverting to the snapshot
 
Also, are there other means to achieve this, apart from buying storage?What about when using ext3?
 
Thanks in advance,
Oren
