I suppose I should have commented on that ;) We're not running FreeBSD 5 on these production machines yet ... but it's likely we will be soon, so I'm considering using snapshots. To my understanding, we still have to stop Cyrus while the snapshot is being created (to ensure consistency) but since a snapshot takes a lot less time than an rsync, this should be a big improvement. Once the snapshot is created, rsync can take as long as necessary. -- Bill Moran Potential Technologies http://www.potentialtech.com _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
