I have a Synology DiskStation NAS that I use for Time Machine backups on my LAN. I want to be able to back up when I'm away from home. I've tried:
- Connecting via L2TP VPN running on Synology
- Connecting directly to Synology via AFP
Through both of these methods I can mount the Time Machine share in the Finder, and I've confirmed read/write access to the share when connected over the internet.
However, when I've mounted the share over the internet, and try to "Back Up Now," I get a message that it couldn't find the disk. Even though the disk is mounted.
