The most professional way of performing a backup of a large dataset is having another server, and using
zfs send
. But if you're looking for a cheaper solution, you can use tar.# Create a snapshot of your dataset. # this way, you are ensuring that all information is consistent # and complete for that moment in time. sudo zfs snapshot -r zroot/media@2017_09_02_hddbackup # navigate to backup cd zroot/media/.zfs/snapshots/2017_09_02_hddbackup # mount your external HDD # (you should have already formatted/partitioned it) # (to UFS using gpart) mount /dev/yourhdd /mnt/backup tar -cvzf --multi-volume --file=/mnt/backup/backup.tar <files>
