DPM for WAN backups Question RRS feed

  • Question

  • I will be using DPM 2010.  I have remote sites on a 2mbit connection to the corporate office.  I am going to have some sites with two servers.  Using DFS, i'll replicate each site's local files to the second server as an 'on-site' backup.  Using DPM, I plan to backup those files to my corporate office over a 2mbit connecdtion.  During the day, the backup would be throttled to roughly 768kb and after hours unthrottled.  Is doing this OK?  Some sites may have 50GB and others may have 500GB.  The initial backup or replica for DPM will be done locally, then a consistency check performed which should not take that long.  Is it recommended to have a DPM server at each site?  Should my DPM WAN backup be backing up an already performed local DPM backup at each site?  IE - a local DPM server backing up files and a remote DPM server backing up each site's DPM server's backups?  Make sense?  Sounds a bit confusing.

  • Hey Zach,
     
    As usual, my answer will be... it depends...
     
    Basically, the 2 mbit connection to the corporate office should be enough.
     
    Your scenario seems perfectly usable in my opinion.  You are right that you should do this with offline backups because other wise the 500 GB will probably kill your lines for a few days
     
    If you see that this scenario doesn't work (because your lines are saturated by other applications) then you still can decide to place a DPM server on the locations and use the corporate DPM to protect them during evenings or so.  But I would suggest to start with the first scenario.  Since DPM only transmits the changes, it should work.
     
    I have used this scenario already a few times with customers and it works quite well.
     
    Just my 2 cents,
    And if you have additional questions...
     
    Cheers,

  • Thanks for the input.  Does anyone know of any documentation Microsoft has on the topic?
