See Appendix B for some additional best practices
22 Setting up IBM TSM on the Dell™ DR4X00 Disk Backup Appliance
3 Set up the DR4X00 Cleaner Once all the backup jobs are setup the DR4X00 cleaner must be scheduled. The DR4X00 cleaner should
run at least 6 hours per week when backups are not taking place, generally after a backup job has
completed.
Performing scheduled disk space reclamation operations are recommended as a method for recovering disk space from system containers in which files were deleted as a result of deduplication.
23 Setting up IBM TSM on the Dell™ DR4X00 Disk Backup Appliance
4 Monitoring Dedupe, Compression & Performance After backup jobs have run the DR4X00 will track Capacity, Storage Savings and Throughput on the
DR4X00 dashboard. This information is valuable in understanding the benefits the DR4X00.
NOTE: Deduplication ratios increase over time, it is not uncommon to see a 2- 4x reduction (25- 50% total
savings) on the initial backup. As additional full backup jobs complete the ratios will increase. As
mentioned before backup jobs with 12 week retention will average a 15x ratio in most cases.

Appendix B
DR4X00 and TSM Best Practices / Considerations
Deduplication
DR4X00 has inline deduplication built in and does not require any additional deduplicaiton to be done
ahead of data being written to the DR4X00 device. The DR4X00 device will remove any redundancies in
the data before the data is stored on disk.
Enabling Deduplication before the data stream is sent to the DR4X00 device will cause the data to be
obfuscated not allowing the DR4X00 devices to achieve optimal dedupe savings. It is highly
recommended that deduplication is not done before the data stream is sent to the DR4X00.
Compression
DR4X00 has compression built in and does not require any additional compression to be done ahead of
data being written to the DR4X00 device. The DR4X00 device will remove any redundancies in the data
before being stored on disk.
Enabling Compression before the data stream is sent to the DR4X00 device will cause the data to be
obfuscated not allowing the DR4X00 devices to achieve optimal dedupe savings. It is highly
recommended that compression is not done before the data stream is sent to the DR4X00..
Encryption
Enabling Encryption before the data stream is sent to the DR4X00 device will cause the data to be
obfuscated not allowing the DR4X00 devices to achieve optimal dedupe savings. It is highly
recommended that encryption is not done before the data stream is sent to the DR4X00..
DR4X00 supports encryption on the wire for transferring data to remote sites using replication. In future
versions of the software it will support encryption on disk as well.
Space Reclamation
For optimal performance, DRX00 and TSM backup and space reclamations jobs should be scheduled to happen at
different times.
