    HSM Restore Method

    In recent updates, the setting for the Cloud Backup restore job now includes the High-Speed Migration (HSM) restore method and is now enabled by default. This utilizes the Migration API as a new approach to enhance the speed of large-scale recoveries.

    The HSM restore supports SharePoint Online, OneDrive, Project Online, Microsoft 365 Groups, Teams, and Viva Engage in both app profile authentication and service account authentication, and HSM restore jobs can support restoring content larger than 15 GB.

    However, the Migration API is not available for users of Microsoft 365 operated by 21Vianet in China. It is also not available for users of Microsoft 365 with the German cloud using the data trustee, German Telekom, but it is supported for users in Germany whose data location is not in the German data center.

    The data export jobs, the security-only restore, restoring sharing link permissions, and restoring to a storage location will not use the HSM restore method.

    Refer to the following for the scenarios of HSM data recoveries. Note that if you are concerned, you can contact AvePoint support for help to disable the HSM method.

    - Select sites, subsites, document libraries, custom lists, calendar, or folders to restore. > ***Note**: HSM restore does not support apps either. - The restore destination must be a container in the SharePoint Online site or the user’s OneDrive.

    Note the following known issues:

    - If an item with the same row ID exists in the destination’s recycle bin, the HSM restore job to restore this item with **Overwrite** content conflict resolution will create this item in the destination with a different row ID. - If you select multiple folders to restore and there are files using the same name, the HSM restore job to restore those folders with the action of **Merge** may fail because of the conflicts. - The Device Channels lists are affected by HSM restore jobs. The default channel item cannot be updated.
