apt install -y linux-headers-$(uname -r) zfsutils-linux

2. Creare un pool

zpool create storage raidz /dev/sdb /dev/sdc /dev/sdd

zpool scrub tank
echo "0 2 1 * * root /sbin/zpool scrub tank" >> /etc/cron.d/zfs-scrub

6. Replica remota

zfs send tank/backup@2026-03-01 | ssh root@server-remoto zfs receive pool/backup
zfs send -i tank/backup@2026-02-01 tank/backup@2026-03-01 | ssh root@server-remoto zfs receive pool/backup

7. Monitoraggio

zpool status
zpool list
zfs list
