<replying to myself here> I read somewhere that this isn't a problem with rsync, that it only copies atomically. So are snapshots even needed if using rsync? I couldn't find anything about this issue on the man page, but it is a huge man page. Also couldn't find anything about this issue in the rdiff-backup man page. Another question: I'm curious as to the relative merits of rdiff-backup vs. rsync snapshots (http://www.mikerubel.org/computers/rsync_snapshots/). Am I mistaken in thinking that the rsync snapshots method would be very inefficient if a small part of a large file (like revision control databases) changed regularly? How much overhead is involved in all those hardlinks compared to rdiff-backup's metadata overhead? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
