GFS Rotation Jobs on Deduplication Devices

Deduplication devices cannot be assigned to media pools, so consider the following when setting up a GFS or Rotation scheme on these devices:

When you select a deduplication device as the destination device in a staging operation on a GFS or Rotation job, you will not be permitted to specify a media pool name. You will be permitted to submit the GFS or Rotation scheme without media pool.
When you select a deduplication device as the destination device in a GFS or Rotation job in a non-staging operation, media pool is not used and media will never be overwritten. Data is written to formatted media in the deduplication device group, if one exists. If one does not exist, blank media is formatted with the current data and time.
When you select a deduplication device as the destination device in a GFS or Rotation job in a staging operation, the behavior of the staging phase is not changed, but the migration phase will never use a media pool and never overwrite media. Data is appended to formatted media in the deduplication device group if one exists. If not, blank media is formatted with the current date and time.
With GFS or normal rotation, with Append Media or without Append Media, backup jobs saved to deduplication devices behave in the same way.

Note: For more information about GFS rotations, see Rotation Schemes.
