Subject: snapshots of directories
Date: Tue, 12 Jan 2010 03:12:43 +0100 [thread overview]
Message-ID: <20100112031243.09e072b0@simplux> (raw)
I try to take a snapshot of a single directory, e.g. root:
> btrfsctl -s root.2010-01-12 /root
operation complete
Btrfs v0.19-4-gab8fb4c-dirty
Then I take look what's inside the newly created snapshot:
> ls -l /root.2010-01-12/
total 0
drwxr-xr-x 1 root root 1192 2010-01-03 20:32:12 bin
drwxr-xr-x 1 root root 76 2009-06-25 0:40:35 boot

drwxr-xr-x 1 root root 4490 2010-01-05 20:15:53 lib
drwxr-xr-x 1 root root 124 2008-04-27 14:53:39 mnt

drwxr-xr-x 1 root root 7676 2010-01-11 0:35:41 root
drwxr-xr-x 1 root root 0 2010-01-12 1:56:17 save
drwxr-xr-x 1 root root 0 2010-01-12 1:55:58 save2
drwxr-xr-x 1 root root 3804 2010-01-06 2:36:08 sbin
drwxr-xr-x 1 root root 0 2007-11-10 3:35:28 sys
drwxr-xr-x 1 root root 358 2010-01-11 18:44:29 tmp
drwxr-xr-x 1 root root 176 2009-12-29 17:08:37 usr
drwxr-xr-x 1 root root 72 2010-01-05 20:03:00 var
It seems that always a snapshot of the root is taken instead one of the
specified directory? Is this by design?
Snapshotting the root works fine, but if you take several snapshots it's a bit
"recursive", because every new snapshot contains all previous snapshots.
Greetings, Michael
