Backup and restore database or files in remote site RRS feed

  • Question

  • Dear All,

    We have a DPM 2010 server installed at Headquarter.
    And there are a few remote site which have some Exchange server 2007.
    The bandwidth of the WAN is around 3Mpbs.

    I understand that once the base replica created, the synchronization just use not much bandwidth.
    It should be ok afterward.

    My question is if someone request to restore database or files, those files will be transfer from Headquarter to remote site.
    For example, the file size is 2GB, and it's necessary to transfer full 2GB data to remote site.

    I'm not sure whether this solution is feasible or not, or my assumption is not correct.

    Please advise.

    Thanks,
    Tommy

  • Hi Tommy!

    I designed a DPM solution for a enterprice company here in Sweden. The company had 5 remote sites and one HQ site. On every remote site there's a primary DPM server that protect the primary workloads for that site.

    On the HQ site thers 3 secondary DPM servers that will backup the primary DPM servers data.

    Restore over a poor WAN access is a tricky part. The best you can do is:

    1. Install primary DPM servers at your branch offices

    or

    2. Upgrader your WAN access.

  • Hi

    When you create your protection group your able to create your replica volume manually. This is a great thing if you have a poor WAN connection. You can also use the on-the-wire-compression to optimize your traffic between sites.

    Here's a link that gives you a hint for how long it will take to backup or restore information http://technet.microsoft.com/en-us/library/ff399167.aspx

    There's a minimun limit of 512 kb for the backup or restroe to work. Please note that minimum isn't the best... http://technet.microsoft.com/en-us/library/ff399051.aspx

  • Hi Robert,

    Thanks for your information.
    It seems that it takes long time to create/restore 200GB data.

    From the url you provided, it shows that it requires 284 hours to restore 200GB in 2Mbps link.
    http://technet.microsoft.com/en-us/library/ff399167.aspx

    It seems that it may not feasible to restore data through the WAN when data size is large.
    May be it is necessary to have a local DPM in each site

    Is there any best practice or cases similar to this environment can be share ?

    Regards,
    Tommy
