Subject: snapshot merging?
Date: Sun, 21 Sep 2008 14:22:38 +0200 [thread overview]
Message-ID: <48D63C8E.2060802@wpkg.org> (raw)
At the beginning of August, Mikulas Patocka posted to linux-kernel
mailing list about adding snapshot merging to LVM[1].
Basicaly, snapshot merging means that it is possible to turn a snapshot
back into its origin.
Using LVM, however, means that you need to have free place outside of
the filesystem (i.e., in physical volume) to make snapshots, which is
not always possible on workstations and some servers.
Is something similar available, or planned, for btrfs? I didn't find
anything similar on "btrfs design" page in the wiki.
