From: Luca Ferrari To: freebsd-questions Content-Type: text/plain; charset=UTF-8 X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.22 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 01 Jun 2016 08:35:07 -0000 Hi all, so far I'm using rsync to keep in sync a couple of removable media (well, up to four) where one is the "master" and the others are a cascade backups (meaning they are set at different time). So far so good. One problem is that I tend to change things in the master, e.g., bulk file renaming or moving, so when I replicate it on the backups I have to force the deletion of no more existing content. This approach, however, relies on the fact that the master is good. My fear is that if the master corrupts some file, I could possibly loss them if they have also been moved since I will no more be able to recognize them on the slaves. So I would like to have some feature like git (or fossil) for hash handling, but since I'm talking about 290+ GB of binaries I'm not sure this approach could work. Any suggestion?
