Comparison of Si3 V1 and Si3

SEP sesam v. 5.0.0 Jaglion has introduced a new generation Si3 deduplication store. Si3 offers significantly higher performance for backup, restore and migration, as well as backup to S3 cloud and backup to Azure, the new immutable storage feature SiS, resulting in improved performance, scaling, and resource savings.

SEP sesam does not support a direct upgrade from the Si3 V1 to new Si3. However, to use the new Si3 you can:

  • Back up all data again to the newly configured Si3 deduplication store.
  • After configuring a new Si3, you can also create a replication job to replicate from the Si3 V1 to the Si3 store. Replication reads all the data from the source-side store on the source-side RDS and sends it to the target store using the source-side deduplication function. For details, see Replicating from Si3 V1 to Si3.
  • You can also configure a new Si3 and an old Si3 V1 in parallel on the same host by enabling the key enable_gui_allow_multi_dedup.
Noteb

The Initial Seed feature does not work in v. 5.0.0 Jaglion, but you can use it in earlier SEP sesam versions.
