Hi!

I successfully updated to 7.3.0 and moved to internal boot and TPM licensing. Now I'm wondering what a smart backup and restore strategy of the boot SSD might look like?! Is it enough/safe to sanoid/syncoid my boot dataset like all my other datasets to an external drive once a day? How would a bare metal recovery from a failed boot SSD work?

Thanks a lot!

Ok. I think it should be enough to keep my old backup script for the new setup:

mkdir -p /mnt/backup
if mount UUID=6A09-DB37 /mnt/backup; then
  echo "Backup Unraid..."
  /usr/local/emhttp/webGui/scripts/flash_backup
  echo

  echo "Move to destination..."
  mv /unraid-*-boot-backup-*.zip /mnt/backup

  echo "Cleanup..."
  find /mnt/backup/ -name "unraid-*-boot-backup-*.zip" -type f -mtime +30 -delete
  find /usr/local/emhttp -maxdepth 1 -name "unraid-*-boot-backup-*.zip" -delete

  umount /mnt/backup
else
  echo "Error: no backup device found..."
fi

Bare metal recovery is done by creating a bootable usb flash drive with the USB creator and the backup zip file.

I just use the appdata backup plugin to make scheduled backups of my boot device. I then just copy the archive somewhere remote.
