When performing a backup of the system to an external USB drive, the following error appears in the action center “Windows Backup could not create a zip file. This could be because the drive that Windows is installed on does not have enough space or it could be a temporary error. Make sure you have at least 400 MB of free space and try again". The error code is 0x81000015.In fact there is enough free disk space actually.
There are some conflicts between Windows Backup and third-party software programs that are associated with .zip files.
1. If you have Carbonite backup utility installed, disable the utility.
2. If you have IDrive applications installed, disable the applications.
3. If you have StuffIt installed, remove .zip associations from StuffIt.
4. If you are running other third-party software programs that are associated with .zip file, disable the programs.
