Increasing Chunk Size for Tape Backups

This parameter affects tape backup operations. A higher chunk size gives a better throughput. A lower value for this setting is recommended for frequent checks against slower data protection operations, especially when data is moving across a WAN link.

Procedure

  1. From the CommCell Console ribbon, on the Storage tab, click Media Management.

    The Media Management Configuration dialog box appears.

  2. On the Chunk Size tab, click the Agent, and then enter 8 in the Chunk Size (MB) column.

    Note:

    • Granular restores will be slower using this setting, however, large restores will be faster.
    • This setting does not apply to database backups where the chunk size is 16 GB by default.
  3. Click OK.
