Any one have a recommendation for backing up three VPS and a 2tb nas? Glacier is too expensive for retrieval. Back blaze good?

If it's looking for a UUID and finds it on /dev/sda3, that's the one it'll use, even if the same UUID is on /dev/sdb1 . I think. IIRC, the label detection code in mount did that the last time I looked at it. (I know about the UUID copy because I do that here at work all the > time. In my case, it’s a feature.

Or the -U option of tune2fs if you've already done mkfs and copied stuff. IMHO, using filesystem labels is preferable to using UUIDs in /etc/fstab . Labels can be made short and meaningful to humans, while UUIDs really can't. (OK, -U feedface-dead-beef-0000-123456789abc works, but is silly.) Distros probably go the UUID route because it's generally easy to assume that UUIDs are unique, while filesystem labels may not be. -- Crow202 Blog: http://crow202.org/wordpress There is no Darkness in Eternity But only Light too dim for us to see. --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.phxlinux.org To subscribe, unsubscribe, or to change your mail settings: http://lists.phxlinux.org/mailman/listinfo/plug-discuss
