Subject: snapshot send with parent question
Date: Sat, 19 Apr 2014 18:00:57 -0400 [thread overview]
Message-ID: <87bnvxasiu.fsf@maru2.md5i.com> (raw)
Assume the following scenario:
There exists a read-only snapshot called a.
A read-write snapshot called b is created from a, and is then modified.
A read-only snapshot of b is created, called c.
A btrfs send is done for c, with a marked as its parent.
Will the send data only contain the differences between a and c? My
experiments seem to indicate no, but I have no confidence that I am not
doing something else correctly.
Also, when a btrfs receive gets a stream containing the differences
between a (parent) and c, does it only look at the relative pathname
differences between a and c in order to determine the matching parent on
the receiving side?
