Fast Recovery

ArGest Backup uses a tape drive’s built-in physical block processing to keep track of where every file is located when written to a tape. This allows ArGest Backup to restore files written onto large-capacity tapes – such as LTO-7 or LTO-8 media – in minutes. Even on archives consisting of multiple tapes, ArGest Backup will only ask for the tape or tapes that contain the data being restored and use the drive’s fast-seeking capabilities to locate a file directly rather than scanning through all tapes used in a given archive. That means that even on a fully loaded LTO-8 tape, restore of physical data will begin in 5 minutes if the tape must seek to the very last block; much more quickly if the starting point is much earlier on the tape.
