Quite wrong. If you want to use the zfs send | zfs receive along with zfs snapshots tools the backup target *needs* to be ZFS. If you plan to use the zfs send | [ tar | gz ] then you can backup the snapshots anywhere you want in a compressed form. a great day, v > > > all your 3 solutions are filesystem-independent > > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to " > freebsd-questions-unsubscribe@freebsd.org" >
