AN APPARATUS AND METHOD FOR FILE BACKUP USING MULTIPLE BACKUP DEVICES

摘要

A method and system are provided for file system backup using multiple backup devices in parallel. The system (100) stores files across the backup devices (120-1, 120-2, 120-M) which connected to a storage unit (110) through a communication link (130), by first copying small files of sizes below a calculated threshold size, and then splitting into segments those files that are larger then the calculated threshold size. For each file segment, the system affixes a unique segment header. At restore time, a restore program starts the restore from the first file segment and follows to the next file segment according to information specified in the file segment header. A computer program, resident in control unit (140) is responsible for controlling the backup process.
