Planning for a tape-based data protection solution
Plan for a data protection solution that includes disk-to-disk-to-tape and disk-to-tape backup operations to optimize storage.
Planning roadmap
Plan for the tape solution by reviewing the architecture layout in Figure 1 and then completing the roadmap tasks that follow the diagram.
In this data protection configuration, the server uses both disk and tape storage hardware. Storage pool staging is used, in which client data is initially stored in disk storage pools and then later migrated to tape storage pools. For disaster recovery, tape volumes can be stored offsite. Offsite options include physically moving a second copy offsite by a courier or electronically vaulting copies offsite to a remote library.
Tips:
- In the described solution, data is migrated from disk storage pools to tape storage pools. However, instead of migrating the data, you can use the tiering-to-tape feature that was introduced in IBM Storage Protect Version 8.1.8. With this feature, you can automatically tier data from directory-container storage pools on disk to tape storage. You can specify that all data is tiered based on a specified age threshold, or that only inactive data is tiered based on an age threshold. For more information about tiering data to tape storage, see Tiering data to cloud, tape, or file storage.
- The described solution does not include node replication. If you want to use node replication to back up a storage pool from disk to disk, ensure that the replication operation is completed before data is migrated from disk to tape. You can also use node replication to back up a storage pool on a local tape device to a copy storage pool on a local tape device.
