A run of vbackup in command prompt. Backup according to backupPlan.bs. All files modified in content since jun01 (bak-jun01.inc) are copied to d:\bak. A list file list is generated for all files backed up. The resulting checksums are saved in bak-jul01.inc.
Different parts of the command. This is brief. For complete detail, see the full documentation

I've been using VBackup for 2 years and some, at home and for work. It's been runned on Windows NT 4.0, 2000 server edition, XP home edition, English and Japanese versions. Sorry, VBackup doesn't run on Windows 95 and 98. If demand rises though, I might consider making it work on those OSes.
VBackup doesn't write to CD or tape directly unless the machine has support for writing to CD or tape via the regular Windows file system (like DirectCD or XP), then that will work. Devices that integrate with the Windows Shell like USB flash-memory drives, certain types of digital cameras, etc will work with VBackup
Please read VBackup's full documentation before using it on real data
See here for VBackup's "manual".
