Hello, I am new here, but am working at a company that uses Sage products.  Our payroll person is trying to backup the payroll, and for the last 3 weeks, she has gotten this message:

Ready to backup 257 files to

File\Location

Executing Operation

Backing Up:

The operation did not complete.

CP5 error DiskFull for Zip.Add

Any reason why this is happening and what we can do to fix it?  We are using version 13.1 with all updates in place.
