When you schedule client backups for a period during which
server maintenance tasks are not running, you create a backup
window. This practice is important when you use data deduplication.
Use this process regardless of whether data deduplication is used
with Tivoli® Storage
Manager.
Perform server maintenance tasks in a sequence that avoids contention
between the different types of processing. The server maintenance
tasks are:
- Migration
- Storage pool backup
- Duplicate identification
- Database backup
- Node replication
- Reclamation
- Expiration
Migration and reclamation are the tasks most likely to interfere
with the success of client backups.
Tips: - Schedule client backups in a backup window that is isolated from
data maintenance processes, such as migration and reclamation.
- Schedule each type of data maintenance task with controlled start
times and durations so that they do not overlap with each other.
- If storage-pool backup is used to create a secondary copy, schedule storage-pool
backup operations before you start data deduplication processing to
avoid restoring objects that are sent to a non-deduplicated copy storage
pool.
- If you are using node replication to keep a secondary copy of
your data, schedule the REPLICATE NODE command
to run after duplicate identification processes are completed.
