StorageCraft Technology Corporation has been assigned a patent (8,190,574 B2) developed by Scott Barnes, Draper, Utah, Nathan S. Bushman, Pleasant Grove, Utah, and Maxim Shatskikh, Moscow, Russia, for "systems, methods and computer-readable media for backup and restoration of computer information."
This patent protects HeadStart Restore, which reduces recovery time objectives by pre-staging a backup image as a virtual machine. This enables the restoration of a system in just a few minutes.
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A computer creates a full backup of a target volume by copying sectors of the target volume. Incremental backups are created by copying modified sectors that have changed since a preceding backup. Public accesses to a restore volume are prevented by modifying a volume boot record (VBR) of the restore volume to prevent file systems from recognizing the restore volume or by filtering public accesses while allowing private block accesses to the restore volume. Sector data are copied from the backup files to the restore volume while the public accesses are being prevented. The restore can begin, using previously created backup files, while the backup is still in process creating new incremental backups for the target volume. The restore volume is finalized after restoring the full or any number of incremental backups by restoring the VBR to indicate the restore volume is valid or stopping the filtering of public accesses."
The date of the patent was May 29, 2012. The patent application was filed on March 2, 2010 (12/716,043).
