By directly piping the send to the receive (and it completing successfully), you're guaranteeing the checksum integrity of the filesystem in transit, and enabling both the restore of the whole filesystem, and individual files, if you would ever care about that. If you "zfs send > somefile" and then you need to do a restore, you're only assured to be able to restore onto precisely the same version of OS that originated the "sendfile." And as other people mentioned, you're only able to restore the whole thing - and you're at risk if there's even a single bit data corruption. It should not be difficult to directly pipe a send to a receive - the only obstacle would be if the destination filesystem is not ZFS. Hopefully you can overcome that obstacle. To answer the original question - how to do an incremental - Please see this example: ## Create Full snapshot and send it zfs snapshot sourc...@uniquesnapname zfs send sourc...@uniquesnapname > somefile-Full (or: zfs send sourc...@uniquesnapname | ssh somehost 'zfs receive -F targe...@uniquesnapname' ) ## Create Incremental snap and send it zfs snapshot sourc...@incrementalsnap1 zfs send -i sourc...@uniquesnapname sourc...@incrementalsnap1 > somefile-incremental (or: zfs send -i sourc...@uniquesnapname sourc...@incrementalsnap1 | ssh somehost 'zfs receive targe...@incrementalsnap1' ) ## Create yet another incremental and send it zfs snapshot sourc...@incrementalsnap2 zfs send -i sourc...@incrementalsnap1 sourc...@incrementalsnap2 > somefile-incremental2 (or: zfs send -i sourc...@incrementalsnap1 sourc...@incrementalsnap2 | ssh somehost 'zfs receive targe...@incrementalsnap2' ) _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
