Backup Difficulties

Hello People,

I have started to have backup difficulties using the Naim Backup Web interface. I am using Apple OS X operating system and have been backing up to my 6Tb WD MyBook without a problem, until last week when I started getting this error message "Full Path Does Not Exist" on my differential backup. Did a full backup over the weekend with a shed load of error messages eithers saying no network connection or file exists, which I would expect. Have any of you any ideas please as I am stumped.

Many Thanks Steve
