DPM Disaster Recovery RRS feed

  • Question

  • Hello,

    I have one virtual server with DPM 2010 server. This server have one big iSCSI Target in Storrage Pool.

    When I lost this virtual machine, what is the best practice for Disaster Recovery? Is it possible to create clear new virtual machine with DPM 2010 and connect iSCSI target to this server?

    Is DPM server able to create new "catalog" for this storage disk and data?

    Thanks Jan

  • Hi Jan,

     

    Best practice is to have a secondary DPM server for disaster recovery.

    However, without a secondary server you could restore DPM IF you have a recent backup of the dpm database. Follow the steps to restore the DPM database in this article:

    Thanks,

  • Thanks. Secondary server in small environments is not possible.

    What happens If I have one week old database backup for DPM server? Data on storage pool are up to date but DB will be one week old. What happens?

    I understand that all recovery groups created after backup are lost, but what about data consistency? On storage pool, there will be partitions unknown for DPM after restore?!

    Thanks Jan

  • Hi Jan,

    If you opt not to use a secondary DPM server, but instead keep backups of the DPM DB in some other manner, you should at least backup the dpmdb on a daily basis. Just run dpmbackup -db and move the resulting dpmdb.bak file somewhere secure everyday. If you restore the database from backup you will need to run consistency checks on all protected datasources.

    Thanks,

    Marc
