Date: Thu, 21 Apr 2011 10:17:52 -0700 Message-ID: <201104211017.52341.CACook@quantum-sci.com> Mime-Version: 1.0 Content-Type: Text/Plain; charset="us-ascii" To: linux-btrfs@vger.kernel.org Return-path: List-ID: I have set up a backup server in the garage which does rsync backups of all my servers weekly, and snapshots those backups. It works wonderfully, and I was able to set it up thanks to help from this listserv, thank you. But I'm accumulating quite a few backups now, unnecessarily. After a couple months I only need a representative one, once a month. I am afraid to delete three of my weekly snapshots out of each month, as I'm afraid they're cumulative. I might end up with nothing valid if each builds on the last, forever. How do I resolve this?
