 If a filesystem is already detected on the disks, use the ''-f'' parameter to force creation. If a filesystem is already detected on the disks, use the ''-f'' parameter to force creation.
  
 +:!: To easily identify devices later on, instead of adding them as ''/dev/sdX'', add them with their serial number identifier instead, e.g. ''/dev/disk/by-id/ata-WDC_WD40EFRX-68MYMN1_WD-WX11D6572HSCP''. This will help identify the disk in e.g. ''zpool status''. If you didn't do this, you can still identify disks by using:
 +
 +<code>
 +lsblk -o name,model,serial

 +:!: Apparently, when using ''nc'', the pipe may not close automatically when the sending process is done. When there is no longer any throughput, kill the sending and receiving ''nc'' processes.
  
 If you have ''pv'' installed, it's ideal for showing progress: If you have ''pv'' installed, it's ideal for showing progress:

 +If the source dataset is encrypted, you might want to send it in its encrypted form using the ''raw'' parameter:
 +
 +<code>
 +zfs send --raw storage-master/storage@backup-2024-04-12 | pv | nc server5.nexus.home.arpa 7777
 +</code>
 +
 +If you want to send the difference between two snapshots, you can do so as follows:
 +
 +<code>
 +zfs send -i tank/storage@snap1 tank/storage@snap2 | zfs recv tank/storage
 +</code>
 +
 +This also works with the ''--raw'' option if needed.
