Abstract
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.
