  • Persistent snapshot management system
    Patent number: 7237080
    Abstract: A persistent snapshot is taken and maintained in accordance with a novel method and system for extended periods of time using only a portion of a computer readable medium of which the snapshot is taken. Multiple snapshots can be taken in succession at periodic intervals and maintained practically indefinitely. The snapshots are maintained even after powering down and rebooting of the computer system. The state of the object of the snapshot for each snapshot preferably is accessible via a folder on volume of the snapshot. A restore of a file or folder may be accomplished by merely copy that file or folder from the snapshot folder to a current directory of the volume. Alternatively, the entire computer system may be restored to a previous snapshot state thereof. Snapshots that occurred after the state to which the computer is restored are not lost in the restore operation. Different rule sets and scenarios can be applied to each snapshot.
