Subject: compare COW files
Date: Mon, 20 Oct 2008 20:25:52 -0700 [thread overview]
Message-ID: <20081021032552.2250.qmail@splitreflection.com> (raw)
If I make a cow copy of a file, is there a way find out whether either copy has changed? Specifically, I'm looking for a way to figure out which files have changed since a snapshot was taken, short of traditional and time-consuming file comparisons. It could have some interesting possibilities for monitoring and backup, to be able to quickly compare against a reference snapshot to find changes.
