Deduplication

When this feature is enabled for the backup set, a checksum verification of each backup file which was split into several blocks of varying size will be performed to compare its content and identify which block is duplicated, thus will perform deduplication of data.

Key:

Field Description
Deduplication Scope The two types of Deduplication level i.e., "Same file path within the same backup set" and "All files within the same backup set".
  • Same file path within the same backup set - this type of Deduplication will deduplicate data under the same path during a backup job.
  • All files within the same backup set - this type of Deduplication will deduplicate data under the same backup set during a backup job.
Block size The size of the block that will be used for the deduplicated data.
Migrate existing data to latest version When enabled, the existing data in the backup destination will be migrated to the latest version during a backup job. This option only applies to pre-v5 data which has not been migrated to the latest version. If the data is already in v5, then this option will be ignored during a backup job.


To enable Deduplication:

  1. Slide the switch to the right to turn on the Deduplication option.
  2. Select a type of Deduplication scope.
  3. Click the drop-down button to select the block size that will be used for the deduplicated data. This option is configured to use “Auto” by default.
  4. (Optional) Tick the "Migrate existing data to latest version" checkbox if you want the existing data in the backup destination to be migrated to the latest version during a backup job.
  5. Click [Save] to store the modified Deduplication settings.
