Windows 7: snapshot of backup?

hey, is a snapshot for the system image ? or is it a snapshot for backup of all my music, games, documents, etc? thanks

It depends on what you mean by a snapshot. A full system image backup grabs the complete picture of the main drive and stores it as an archived image. If Windows is trashed rather the need to reinstall and replace everything that was on originally you simply restore the image backup made.

For partial or incremental backups that preserves things like user files and documents and a select list of folders while not preserving the OS or programs installed. With the Windows Easy Transfer tool for example once you put a fresh copy of Wiindows and all programs back on from scratch you simply restore the backup to see all settings and files from the previous Windows install restored.
