snapshot 1 

zfs snapshot -r pool0/diska@primo

iniziale 

zfs send -D -R pool0/diska@primo | ssh root@rvmstor01.rvmgroup.local zfs receive -duv backup/quantum

su backup 

 zfs list -t all

Fare altro snapshot 

 zfs snapshot -r pool0/diska@secondo
  1. zfs list -t all NAME USED AVAIL REFER MOUNTPOINT

pool0 2.45M 308G 19K /pool0 pool0/diska 2.03M 308G 2.02M /media/diska pool0/diska@primo 9K - 1.02M - pool0/diska@secondo 0 - 2.02M -

Inviare incrementale

  1. zfs send -D -R -i pool0/diska@primo pool0/diska@secondo | ssh root@rvmstor01.rvmgroup.local zfs receive -duv backup

receiving incremental stream of pool0/diska@secondo into backup/diska@secondo received 1.01MB stream in 25 seconds (41.4KB/sec)

su backup

  1. zfs list -t all
