Please verify the sha256 hash error

[showstopper]

OK so i found this post - Please verify the sha256 hash? - #11 by Kenny and kenkendk comment:

Most likely the remote file is broken, since it is missing some data.
I suggest you remove the file and then run the purge-broken-files command from the “Commandline” area.

So i tried this and then ran a backup and no errors. So i’ll keep an eye on this one.
