Other files may be in the backupscripts.d directory. During a freeze/thaw cycle, system attempt to run all files in the directory in alphabetical order. Storing any other files in the directory will cause problems.
If writing log files, move the target directory elsewhere. Remove all files that are not intended to run to another location.
To check the status of the VSS writers, open a command windows and type vssadmin list writers
