Seeding can play a vital role in situations where customers cannot afford to transport large amounts of data over the WAN between their branch offices and head offices. In such situations, seeding is often employed as it allows the first bulk transfer of data to complete quickly and without involving the WAN. USB disks or tapes are used to make the first copy (backup). These backup sets are then shipped to the central data center. In the data center, by running a backup job, the data is backup to deduplication storage folders and from then on, updates (Optimized Duplication job) require much less bandwidth.
To transport the first set of data, use the following method and then schedule a duplicate backup job to start optimized duplication.
- Back up your data to disk or to tape using Backup Exec
- Transport the tape or disk to the destination system (CAS or MMS)
- On the destination, inventory and catalog the data.
- Create a duplicate backup job from the disk or the tape to the Deduplication storage folder.
- After successful completion of the duplicate backup job from the disk or the tape to the Deduplication storage folder, create a Optimized Duplicate backup job between the two servers involved (e.g. CAS and the MMS.)
NOTE: You should not use the compression or encryption options for backup jobs that deduplicate data. Data cannot be deduplicated when it is in encrypted or compressed form. Therefore when creating a backup job in step one, ensure compression and encryption options are disabled.
