Creating a new ZFS pool for replication.
First use parted to initialize the partition with a GUID.
gparted print rm 1 rm 2 quit
mkpart "paulbackup" ext4 0% 100% quit
create pool "snaps" from paulbackup
zpool create snaps paulbackup
in case you want to destroy the pool and start over zpool destroy snaps
zfs snapshot paulmedia/shows@init zfs send paulmedia/shows@init | zfs receive snaps/shows@init
incremental zfs send -i paulmedia/shows@init paulmedia/shows@next | zfs receive -dF snaps/shows
The -i flag is the reference snapshot from a previous snapshot, the argument after that is the snapshot to send
list snapshots
zfs list -t snapshot
set lz4 compression on snaps zfs set compression=lz4 snaps
