Use a disk cache to accelerate the recovery
This option is effective for file recovery from backups stored on tapes.
The preset is: Disabled.
When this option is enabled, the software uses temporary files to minimize the number of tape rewinds and thus accelerate the recovery. The software creates the files on a local disk of the machine where the tape device is attached and deletes the files after the recovery is completed.
This option is especially efficient if you recover large files. However, temporary files require as much space as the total size of the files you want to recover.
