  • Hi Gleb,

    In following thread, Mike Jacquet mentioned the limitation of DPM when backing up NAS:

    DPM can only protect data that has a DPM agent installed and that support VSS Shadow Copies, that usually excludes the ability to backup network attached storage devices.  NDMP  - Network Data Management Protocol, is a protocol invented by the NetApp and Legato companies, meant to transport data between NAS devices and Backup devices. DPM has no plans to support that protocol at this time.

    Also it is not supported to add NAS as a storage pool, so backup TO NAS is not supported either.

  • The statement above refers to DPMs ability to back up data FROM NAS. It is correct: you cannot use NAS as a data source, because you need a DPM agent and VSS on source. It does not mean that you cannot use NAS in storage pool: DPM does support iSCSI storage devices, so if your NAS appliance can be accessed using iSCSI interface, then it can be used for disk-based backup in DPM. See Plan for disk backups for more information.

  • NAS storage can be used if it provides iSCSI interface and can be presented to DPM server as block-level storage device.

  • Oh thanks Gleb. I suppose to add that (but if NAS support iSCSI then it could be added to storage pool) but forgot. Thank you for the correction.
