In somewhat-related news, I just found this project via freshmeat: http://freshmeat.net/projects/rsnapshot/?branch_id=43437&release_id=146249&topic_id=19%2C137%2C861
About: rsnapshot is a filesystem snapshot utility based on rsync. It makes it easy to make periodic snapshots of local machines, and remote machines over ssh. It uses hard links whenever possible, to greatly reduce the disk space required. Homepage: http://www.rsnapshot.org/ HOWTO: http://www.rsnapshot.org/howto.html IMHO: rsync is a good tool for this, since you can do an initial backup, then get incremental changes far more quickly via rsync's magic. ...'rsnapshot' uses ssh, and is written in perl. ciao, Ben On Tue, 30 Dec 2003 02:50:36 -0800 (PST) Horst <[EMAIL PROTECTED]> wrote: | Quoting: | """ | From: Hal Pomeranz | Date: Mon, 29 Dec 2003 18:25:29 -0800 | ... | Frankly, using GNU tar is probably a better option precisely because | it doesn't have this particular issue (tar is a "file at a time" | archiver, and is therefore relatively resistant to file system changes | during the archive process).
