    Info

    A valid bucket name consists of 3-62 lowercase letters, numbers, hyphens or dots. It must not form an IP address, and hyphens are only allowed between lowercase letters & numbers, i.e., not before or after dots, nor at the start or end of the name.

    Info

    A valid directory name consists of upper and lowercase letters, numbers, and the special characters !-_.*'(). Other special characters (@&$+?,:;=) and spaces may work if correctly supported by the client being used. Avoid all other special characters (including emoji).

  1. Set a name for the backup task. This will appear later in the DSM task manager.
  2. Enable Compress backup data
  3. Enable Transfer encryption
  4. Enable Backup schedule and set an appropriate execution time
  5. Enable Integrity check schedule and set an appropriate execution time

  6. Recommended: Enable Client-side encryption

    Caution

    Ensure secure key storage.

Backup Settings

15. Enable backup rotation

  • Configure rules. Recommended options are:
  • From the earliest versions: easier to understand guarantees

  • Smart Recycle: more complex rules, but the policy combines high temporal resolution for recently changed files with longer retention of old versions

  • Set maximum number of versions

    Info

    Many versions increase the maximum backup size considerably, but only require additional storage space for changed files. Unchanged files are versioned with only minimal additional storage space.

Rotation Settings

16. Review the summary. Click Finish.

Backup Summary

The first backup will start at the scheduled time.

Optional: Start the first backup immediately

17. Answer the question Run backup now? with Yes. If No is selected, the first backup will start according to the schedule (Step 14).

Info

The first backup can take many hours, so ideally only start it immediately if the device will not be used intensively during the next period.

Start now?
