Cloud account to small

I keep getting messages that i need to do a backup.  But my cloud space is full so it fails.   I have a 2TB cloud account (not with Norton).  How can I get it to use that cloud account.  I have five devices sharing my Norton cloud account. Even the 50GB account is too small.  Is it possible to use another cloud account to archive too.

Norton does not connect with other cloud based storage services.

The only chance you would have is if you can map the other online storage to a drive letter in Windows Explorer. Then you could use that as a destination for the Norton backups.
