Steven wants to replace his existing backup with a new one. He tends to use a thumb drive. But the backup fails and can't backup shadow copies or system restore points. Leo says that malware can be removed by an AVS and that could affect the system restore points because the AVS expects his backup to be infected as well. Leo says that Shadow Copying is a relatively new thing that Microsoft has added, which runs in the background. Leo says that EaseUS is a good backup solution. Imaging is a good thing to do as well.
Paul is looking for software to allow him to backup each version of what he's working on. Leo says that's called "versioning." Windows 7 has versioning, called "Shadow Copy."

It'll copy to a portion to the local hard drive that he can then backup.
There are several third party programs that can also accomplish this:
