I like being the less up-to-date - it is more interesting. :-) I've rdiff-backup on my list of man-pages to read.Among the complications involved with rsync one should consider the potential consequences of a hardware failure during an update phase; the possibility that a file is accidentally deleted and the backup is refreshed before the missing file discovered.That's an issue with rsync, but not with rdiff-backup, which keeps older files. You can restore older versions of files, or deleted files for as long as they stay in the backup. Of course, but (I ask provocatively) - won't that use mailbox rather than maildir format -hence introducing complications of locking? Isn't there an issue in getting this to be a system wide setting not a per-user thing? For a mail server with centralised administration - isn't something closer to the MTA more appropriate?For a mail server, I can't help thinking that the ideal solution would be some (possibly bespoke) mechanism to push emails from the primary server to a secondary server (or maybe just a secondary disk) as it arrives (possibly with a queue as necessary) and not to delete data from the secondary server when it is deleted from the first, but rather to archive the eldest data regularly in order to ensure the disks do not fill. This, however, could not be considered a simple backup by most. [Neil - you'd impress me by naming a tool that would do this 'ideal solution' without the need for writing bespoke scripts...]You can use a procmail rule to send a copy of a mail to a backup file.:0c: /mnt/backup/mail/$USER.backup [BTW - you didn't solve the archiving bit :-P ] That's good - people who agree with me are usually dull. :-)Do we still disagree? :-)Not now, but I'm sure I can think of something, given time ;-) Steve |
