Planning for data deduplication is important because there
are many factors to consider. These factors include database and log
size capacity, data deduplication location, storage pool setup, and
additional hardware requirements.
As part of the planning process, ensure that you will benefit from
using data deduplication. In the following situations, IBM® Tivoli® Storage Manager data
deduplication can provide a cost-effective method for reducing the
amount of disk storage that is required for backups:
- You have to reduce the disk space that is required for backup
storage.
- You must perform remote backups over limited bandwidth connections.
- You are using Tivoli Storage
Manager node replication for disaster recovery across geographically
dispersed locations.
- You either have disk-to-disk backup configured (where the final
destination of backup data is on a deduplicating disk storage pool),
or data is stored in the FILE storage pool for a significant time
(for example 30 days), or until expiration.
