Duplicati supports using as a storage destination. To use the destination, use the following URL format:

msgroup://<folder>/<subfolder>
  ?authid=<authid>
  &group-id=<group-id>

To use MS Group you must first obtain an AuthID by using a Duplicati service to log in to Microsoft and approve the access. See the for different ways to obtain an AuthID.

You can either provide the group email via --group-email or the group id via --group-id. If you provide both, they must resolve to the same group id.

Performance tuning options

If you need to gain more performance you can fine-tune the performance of chunked transfers with the options:

  • --fragment-size

  • --fragment-retry-count

  • --fragment-retry-delay

For most uses, it is recommended that these are kept at their default settings and only changed after confirming that there is a gain to be made by changing them.
