Time Machine backup fails in macOS 10.13.3 (High Sierra)

I have a Macbook Pro running macOS High Sierra 10.13.3 which stopped being able to do a Time Machine backup on two distinct network shares. One of those server is running macOS 10.13.3 and the other is a Synology DS218+. Backups were running fine before the upgrade.

I also have a Macbook, which is still running 10.13.2 which is able to back up to both of these network shares.

Thus I suspect an issue with 10.13.3.

Anyone has got the same issue?

Replying to myself...

Forgot to mention the error message: "The network backup disk does not support the required capabilities."

Turning off the SMB sharing did the trick for me. Seems 10.13.3 doesn't like backing up over SMB.

Many thanks for this solution. This is super helpful. I was having to reboot both the computer and network backup device for each backup prior!

Let's hope Apple fixes this asap!
