AppAssure

AppAssure works well for quick access to point in time backups of Windows machines without having to do a complete restore. The virtual standby function is useful as a disaster recovery or high availability solution. Recent upgrades to the product and rebranding to Rapid Recovery look promising. If your Linux machines are mission [critical] make sure your administrators test restores so they can perform them in a timely manner should the need arise.

Data Domain

Best suited for backup target, that's what it was designed for. The ingestion rate is very high, data exfil not so much. Doesn't work very well as a NAS (though functionally, that's what it is). It's very good at block-level deduplication of disparate types of data.

Pros

  • It's good when there are no issues with the backup. It works well with file level restores if you can get the systems backed up without any corruptions.

  • High data ingestion rate. For inline dedupe, these devices can ingest a saturated Gigabit Ethernet line, plus a FibreChannel from an AS/400.
  • High reliability. In ten years of having at least two units and ingesting 1.5 to 2TB/night of backups, we've replaced maybe three disk drives.
  • Scalability. Dedupe ratios are very good (11:1 for us for all data), and the DD2500 models allow addition of disk trays to expand capacity.
  • Ease of use. Management interface is good, the free Data Domain Management Center Appliance is even better.

Cons

  • We have many repository corruptions and have to blow our backups away. I would not recommend using this if you are keeping a long retention.
  • We upgraded the agent and it created a new base image. Duplicate base images are eating up into our repository space.
  • I would like to see the repositories go away and use the type that was introduced for replay.

  • Dedupe ratios on a per-folder or per-CIFS share basis would be nice, we can only see the ratio per partition (MTree). So it's not possible to see what ratio we get from Tivoli data vs vRanger data, for instance, because they're in the same MTree.
  • The VTL option seems inordinately expensive given it's only software. We held off a long time because of the cost, and only went down that road because the IBM iSeries is inherently unable to do a DR recovery from disk only.

DD has performed flawlessly for almost 10 years as our backup/recovery storage with offsite replication. Given its track record and great support from EMC, we're unlikely to look elsewhere any time soon.

Our initial installation really was not optimum. With the help from Dell Profession Services we were able to get our implementation sized correctly and better understand how to get better deduplication results

Alternatives Considered

We had Replay in our environment already and the price was right. We figured it might be good to stick with one vendor. Replay was a good product and saved us a couple times with the VM exports. Unfortunately, I can't say the same about AppAssure - anything but headache dealing with support daily.

We selected Data Domain due to its integration with our backup software. The Data Domain works well for what we need it to do.

Return on Investment

  • It is taking too much of our time to manage this product to make sure backups are running.

  • Data Domain says 20+ hours per week when compared to using a tape library. Once the unit is configured it basically takes care of itself.
  • With MTree replication we no longer need to send tapes to an offsite storage facility.
  • Having a second data domain at our DR site allows us to perform recoveries from any of our replicated backups. We do not have to order and wait for tapes to arrive.
