1. Get the properties of rpool and other file system. Save this data is case it's required later.
# zpool get all rpool
# zfs get all rpool
# zfs get all rpool/ROOT
# zfs get all rpool/ROOT/s10u7
# zfs get all rpool/export
# zfs get all rpool/export/home
# zfs get all rpool/dump
# zfs get all rpool/swap
2. Now snapshot rpool with suitable name
# zfs snapshot -r rpool@backup2016
3. Destroy not required snapshot
# zfs destroy rpool/swap@backup
# zfs destroy rpool/dump@backup
4. For each dataset , send to data to backup location,
# zfs send -v rpool@backup2016 > /backup2016/rpool.dump
# zfs send -v rpool/ROOT@backup2016 > /backup2016/rpool.ROOT.dump
# zfs send -vR rpool/ROOT/s10u7@backup2016 > /backup2016/rpool.ROOT.s10u7.dump
# zfs send -v rpool/export@backup2016 > /backup2016/rpool.export.dump
# zfs send -v rpool/export/home@backup2016 > /backup2016/rpool.export.home.dump
These files can be transferred to NFS Server. So we can use them in case of restore.
