    Can two Nimble arrays act as backup and DR?

    David Henderson Newbie

      Traditionally Disaster Recovery and Backup have meant two different things. Disaster Recovery is the ability to quickly recover from a big disaster in a main data center by turning data in a DR site into production data quickly. This usually means some type of replication from the data center to a DR site. Backup usually meant backing up data using some type of software solution to control the backup and some type of target (other than the array in the DR). The backup had some type of retention with the ability to do restores on the volume, VM, or file level.


      Current setup

      1. Two arrays from same company, one in data center and on in DR site with replication running between them so my DR strategy is covered
      2. Commvault software running that backs up data in data center to Exagrid box in DR site so my backup strategy is covered


      Lots of moving parts and costs associated with Commvault and Exagrid

      If I go to this setup

      1. Two Nimble arrays, one in my main data center and one in my DR site
      2. Snapshots are happening on the array in the data center with snapshot set to go back 90 days
      3. Replication setup from my data center to DR site

      Can this handle Disaster Recovery AND Backup? In other words, if need be I can:

        1. Turn the data in the DR site into production data in case of a fire/flood in my main data center
        2. Do volume level, VM level, or file level restores


      In the end can I ditch Commvault and the Exagrid box by purchasing Nimble?

          Hi David.

          The biggest question here, IMO, is do you need to have a catalogue of your backups. Currently, CommVault allows you to search for any given item you wish to recover. If you are just relying on Nimble snapshots, there is no native catalogue/search capability. That being said, if you don't need the catalogue, then we can 100% accomplish your goals. In fact, we have a large (and growing) number of customers that do just what you've described. Once you're on Nimble in both sites, you can have the same 90 days of retention (or more if needed). One of the nice things with Nimble is you don't need 90 days at each site if you don't want to. Since you can set independent source and target retention policies, you can keep much shorter retention on one side. And if the time ever comes (hopefully not), you can make the DR array primary for all or a part of your workloads. This can even be handled through our Handover capability for planned transitions.

          Hope this helps!
