FauBackup is designed to maintain a bunch of filesystem snapshots, where through the magic of hard links, older snapshots only takes up space in for files that differ from the most recent snapshot. (Other than the space taken up by the directories themselves, that is.) rync can be configured to do the same thing. This is how I want to operate. In this way, I can, for instance, have a snapshot that is a year old, one that is a month old, one that is a week old, and one that is a day old, and I can do this in much less space than four times the size of the disk being backed up. This hard-link magic won't work if I compress the files as a separate step, however, because rsync won't know how to handle this. Either rsync would have to already have the concept of a compressed mirror, or the filesystem itself holding the backups would have to be compressed. I suppose it might be possible to compress the snapshots after rsync'ing, and then uncompress them before the next rsync, but I imagine that that would be a mighty slow and cumbersome way of doing things. |>oug --- Send mail for the `bblisa' mailing list to [EMAIL PROTECTED]'.
