Shadow Copy feature on Servers with DPM RRS feed

  • Question

  • Hello There,

    Is it a recommended configuration to have Shadow Copy enabled on the file servers which are also being backed up by DPM? Please suggest.

    And what are the pros and cons of using this mixed configuration.

    Regards,

  • Hi,

    Adding Pros and Cons.

    Local shadows enabled on the DPM protected computers.

    PRO - Clients will get previous versions of files directly off of the protected server. May be faster copy depending on network topology and speeds.

    PRO - Server owner has more control over the length of time previous versions are maintained based on shadowcopy storage limits.

    CON - Uses local storage on file server, so may limit shadow copy storage size.

    CON - Users will never see previous version on the DPM server, so that may limit self-recovery of file if they are maintained for a longer time on the DPM Server and not available in local shadow copy.

    CON - Unless educated, clients (users) may not know that backups of files are available on the DPM server, so may settle for a previous version available to them only from the file server instead of asking for a restore for a more desirable version from help desk.

  • Hi,

    I am not really sure if it is recommended but we use it for years now without any issues on more than 100 Servers.
    Shadow Copies have their own Partition.

    Reason on our side is that the 1st Level Support has the ability to use that but doesn't have permission to Access the DPM Servers.

    Furthermore we  have different Retention times for Shadow Copies and DPM backups.

    regards
