Is it is possible to point to other partition's datablocks?

Assuming you're willing to write new code, of course you can do that. Examples: Device mapper does it. See the last email I just sent with DM pseudo code for COW. Note, DM calls them volumes, not partitions but the logic is the same. Also, a lot of filesystems support a separate journal partition. So you have data in the journal that references the primary volume. Greg
