An intermediate storage area for caching backup data. Specify per DLE in amanda.conf(5).
A holding disk provides these key benefits:
- It allows data to be streamed to media at full speed, preventing tape buffer under-runs and shoe-shining of tapes.
- It can act as a hedge against media failure. Data is first backed-up to the holding disk, and then later spooled to media when it is available.
- It gives you dump parallelism. With a holding disk, amanda can do more at the same time, speeding things up. It can build several dumps simultaneously on the holding disk while copying one to tape. Changing a tape doesn't mean stopping the backups.
