Cohesity vs. PowerProtect DD Series

Cohesity is very well suited to protecting virtualised workloads and is a significant improvement over IBM Spectrum Protect which we’ve replaced by Cohesity. We also protect a Netapp workload and whilst the on-prem side works really well careful planning of protection jobs is needed if you’ll be archiving these to Cloud.

When used as a backup target PowerProtect DD models offer incredible density and can efficiently replicate to another cloud-based or offsite unit. Most complaints about these have been addressed in software over the years and they are now a intuitive and easily managed backup system. You are not buying a Swiss army knife, you are getting a machine designed for a purpose, use it for that and you will not be disappointed. While they have the ability to serve as a CIFS server, they are not a filer and lack many of the features inherent to filers and are a poor substitute.

• The simplicity of the solution and the support behind implementation, training, and continued support.
• The implementation and training are all done through the sales engineer, which provides for a seamless and great experience when it comes to starting with a new vendor.
• How fast the solution works. When it comes to implementation (which is done in an hour or so) to backups, to actual recoveries, everything is just quick.

• It writes backups quickly. DDBoost add-on is very useful as well for improving backup speeds.
• DD is very efficient in its use of capacity. It dedupes and compresses very well.
• It spans to large capacity amounts.

• Reporting could always be better- executive-style reports have to be generated from data at multiple points.
• Some tasks that could be brought to the UI that today we have to call support on (for example when an NFS mount is still active but we cannot see it from the UI)

• Depending on the model of Data Domain, there is a limit to the number of NFS/SMB threads that can run concurrently. When this limit is reached, the system is slow to respond to client requests.
• Data Domain support is very slow to turn out new features and bug fixes in their code.
• OS upgrades are very slow and disruptive.

We have been very pleased with this backup solution. It is fast and reliable, and supports our VMware infrastructure. The company's support has been great, including proactively replacing our nodes when the flash memory was reporting high wear. Support is offered on-shore as well. We plan on continuing to use this product for the foreseeable future.

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.

The Cohesity platform with its user interface is easy to implement, rack space-saving, and easy to use on a daily business basis. Backup jobs and policies are easy to define, multiple machines and objects can be grouped for the same tasks. In general, Cohesity makes backup admins' lives much easier.

Support is quick to respond but lacks that ongoing responsiveness if the issue is not simple. There will be large gaps in replies if they need to resort to escalation and when there are timezone differences between yourself and the person who picked up the ticket.

Customer support has had some ups and downs here. We've had several issues with EMC support before and during the acquisition by Dell, but in the last 18 months support has been top notch. Quick and knowledgeable help is but a chat away, or they will call you back so you don't have to wait on hold. The team supporting us is responsive and is quick to assist with any request or issue.

We looked at Veeam and although it's a great product when we priced out the licensing of both primary and disaster datacenters it became much too expensive. Rubrik is a great product and very similar to Cohesity. In the end, Cohesity had a secondary storage play as well as a better UI and better compatibility with lower tier cloud storage. We also like the way Cohesity did protection jobs vs Rubrik's virtual machine centric backup. CommVault is a product we still use today due to its massive features and the ability for bare metal backups. Cohesity does a much better job in the area of UI simplicity, virtual backup ease, and ease of management.

We already had Avamar in place, and since we have a good ecosystem of Dell Solution suite and wanted to evaluate PowerProtect DD also from that perspective, hence we thought of going ahead with it. We knew the limitations with Avamar and PowerProtect DD were right there from that side of the business.

• Cost savings from having to purchase and manage physical tapes, as well as the man-hours to swap them in and out and store them off site.
• Extremely fast recovery times, can bring up a restored VM back in our environment in under a minute. Get back up and running much quicker.
• Simplifies our disaster recovery strategy.
• Initial cost can be pricey depending on your storage needs.

• Positive: The high compression (58.0x) and data reduction (98.3%) have allowed us to optimize the storage for efficient usage.
• Negative: even after adding capacity, we are running out of space. Adding capacity adds to the overall TCO (e.g. lease cost).
