ZFS send....

[Zedicus]

so i have been using RSYNC for my files and folders and ZFS send | receive for snapshots. but it would seem to me that ZFS send could move a files and folders (a snapshot is basically that, no?)

but all the docs and the oracle page only show ZFS send as pertaining to snapshots. IE:
# zfs send tank/data@snap1 | zfs recv spool/ds01

is it possible to ZFS send a complete folder? or even a complete tank?

(im hesitant to just start bashing out commands, still green in ZFS land.)

thanks

I am going to say yes on the second although normally you send snapshots where a snapshot would be a dataset at a point in time.

zfs send replicates a ZFS filesystem (this is like a partition) not a simple folder
This is based on snapshots to hava a valid state

You can also use it recursive ex on a pool to transfer all filesystems below.
On first run it transfers all data, on next run only modified datablocks.

can i get an example of what that command would look like?

first run
zfs send tank/data@snap1 | zfs recv spool/ds01

or via ssh
zfs send tank/dana@snap1 | ssh host2 zfs recv newtank/dana

next run (incremental, transfers the modified datablocks between the two snaps)
zfs send -i tank/dana@snap1 tank/dana@snap2 | ssh host2 zfs recv newtank/dana

i see what you are saying in that it updates the snaps.
