A better idea than messing with your personal computer's VSS services (which I would say is bad), would be to set up a file server where you don't have administrative privileges for your system to execute anything on said file server (that way the files are on the file server and can always be rolled back to the shadow copies the *file server* takes). Or, a persistent backup system that backs up your data every X minutes. It depends on how critical the data is.
Therefore if VSS is needed as a buffer:
#1 backups are insufficient
#2 your security is insufficient
#3 your system needs to be locked down more*
*I often lock down computers for people who are not technical / prone to getting malware
