PowerProtect DD Series vs. Quest QoreStor

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 product can be run on-premises or in the cloud. It is a fantastic option to reduce the size and storage requirements of backup jobs. If your backup system can already produce a reliable reduction in storage up to 75% then I would say the QoreStor appliance would be irrelevant in your case. It does not perform backups itself. It is simply an extra step to reduce size, encrypt and offload backups to the cloud. this reduces the load on a backup system to handle other tasks while the QoreStor takes over.

• 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.

Incentivized

• Deduplication
• Compression
• Cloud Connection
• Replication

• 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.

• Disaster recovery from a populated cloud bucket needs improvement
• It would be nice to have some limited integration into the KACE SMA product
• The appliance is low resource use and virtual, but better access to system settings would be nice.

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.

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.

The support team is the main reason I am sticking to Quest/KACE products. They are stellar to work with and always responsive when I need help. The team listens to the user's recommendations for added features and tends to add the ones that really have merit. Support is everything when it comes to working with such a company

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.

When I evaluated the Dell system it was an entirely new server on-site, with licensed levels of inlocking the storage it had on board. For a smaller organization, the Dell system was not cost-effective with a large upfront payment, and additional hardware to manage on-site. The QoreStor system was a virtual machine that could pop into my current system and just use allocated storage already in place. In addition, the upfront cost was dramatically less than the Dell option and no additional hardware

• 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).

Incentivized

• Dramatically decreased cloud storage costs
• Backup Jobs take less time on the Backup system
• An additional level of backup and encryption
