I used Veritas Backup Exec for years to a 50gig tape. I now have an external 250gig drive and switched to handy Backup (from novastor). I like it much better because it does incremental backups and actually saves the files where you can do a normal copy if you need one of them. The Veritas product saves to a large file. You need the program to get one file from the restore function. The Handy Backup is fast. I triad Win Backup and it was slow. Handy Backup also only costs $30. I temporarily stops for files that are in use and logs them. You never need to look at the process. It is like doing a large XCOPY command.
