Backups and High Availability come to mind.

If there’s any other place you’d be allowed to install a second node on, ideally served by another ISP (since we talk about remote access), you can do that. This can be your friends, or family, or someone else you trust.

Just have 2 NAS devices with equal drives in each and let them work in a high availability cluster. This way, you’ll have near 100% uptime and a backup in case something goes wrong.
