You could boot from your backup, if you zfs sent it the relevant snapshots of your boot datasets and installed GRUB on it. So: replace main drive, boot from backup, backup the backup to the new main drive, reboot from main drive. If you want to only backup your user data (home directory) then yes, you'd have to re-install, then restore the user data from the backup. And yes, the restore procedure would involve a zfs send from the backup to the new pool. > It won't be quick, but replacing a failed single boot drive never is. > Would it be possible to combine the send/receive backup with a > scripted installation saved on the external media? Something that That would be nice, primarily so that you needn't backup anything that can be simply re-installed.
