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  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
