For Windows (and Mac?) it's pretty straightforward, but for Linux you have to use rsync (or some third-party packages for restic, bacula, (etc.)), the tricky thing being that you need to setup SSH access for the user you want to backup as, as by default it's only for the admin. And it uses some funny SSH config that gets rewritten when the system reboots.

So!, you need to - SSH in as an admin and add the username you want to backup as to /etc/ssh/sshd_config, line AllowUsers. - Restart the SSH service with (you have to do the whole command, even if you're in the directory) /etc/init.d/openssl_signature.sh restart. - (If that doesn't work do /etc/init.d/services.sh restart to restart all services)

The documentation for third-party packages is near universally garbage. Rarely do links to thinks like tutorials point to anywhere relevant to using on a QNAP, and oten they point to pages that don't even exist!

Upgrading to disks to higher capacity ones was a bit obtuse. Installing is fine, just hard to find the right menu to be in to increase their allocated space.

1. Storage & Snapshots > Storage:Storage/Snapshots > Manage > Manage > Replace Disks One by One
   • Click on disk and press 'Change'.
   • NB: Good to wait a bit for the disk to stop properly?
   • NB: Might want to set the 'priority' higher temporarily.
2. Storage & Snapshots > Storage:Storage/Snapshots > Manage > Manage > Replace Disks One by One
   • Click on Expand Capacity (yeah, fucking hidden)
   • Don't be afraid if it says something about 'execution' instead of 'expansion' D:'
