Comprehensive integration and user-friendly dashboard enhance data protection workflows
PowerProtect Data Manager lacks the tape-out functionality, which is important for organizations relying on it for offsite backup. While PowerProtect Data Manager offers a workaround, it's not always accepted, notably by sectors like banking. Additionally, I would like PowerProtect Data Manager to provide microservices and container backup for modern applications.
Andrew Mcbeath - PeerSpot reviewer

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I love that it has an interactive GUI, and it is not complicated to use."
"The most valuable features of the solution are flexibility and data protection."
"Dell PowerProtect Data Manager helps to reduce the amount of data being transferred and stored."
"The management part of Dell PowerProtect Data Manager has improved significantly."
"Dell PowerProtect Data Manager is a comprehensive backup software that integrates with Dell backup storage to enhance data protection."
"One notable feature is its robust backup support for Kubernetes and container environments. Additionally, PPDM stands out for its ease of deployment and management compared to other backup solutions. It is highly user-friendly, allowing users to quickly learn and implement backup and restore processes within a week. PPDM represents the next generation of backup software and is comparable to offerings from other vendors. Furthermore, PPDM prioritizes security with various access controls, such as user and database access controls. Its deployment tool is also known for its simplicity."
"The deduplication is the most valuable feature because it helps to control the overhead."
"The product's initial setup phase was easy."
"The hardware is strong and all the equipment has a good infrastructure. Personally, I think it's the best storage product in HPE for small to medium-sized businesses."
"The initial setup is simple."
"Technical support is quite good."
"It's easy to backup data, manage. A"
"The most valuable feature of the solution is its UI. The product's UI makes it easy for users to configure the tool."
"The initial setup is one of the most user-friendly B2B user solutions. It's good, it's easy. Deployment usually takes less than one day. You only need one person for deployment and maintenance."
"Deduplication is the most valuable feature."
"HPE StoreOnce is particularly useful in situations where organizations require a backup solution to store their data. Its deduplication feature is quite impressive, providing a deduplication ratio of around 25 to 26."
 

Cons

"The marketing strategy is lagging behind competitors such as CommVault. Dell needs to improve its market presence and communication with customers and solution providers."
"When I raise a ticket, it sometimes takes a while to get a response."
"The interface is too complex."
"Management is difficult and it is hard to determine when things aren't working properly."
"There is always room for improvement. The compression ratio should be improved as well as the efficiency."
"They should include a feature similar to S3 bucket."
"PowerProtect Data Manager is missing a feature for takeout, which means I cannot store backup data off-site within the software. This is a limitation for organizations that require off-site solutions."
"The solution should enhance its user interface and make it more flexible."
"Cloud integration needs to be simplified."
"improvement? HPE StoreOnce has a limitation with respect to controllers. Other tools offer more than one controller. I feel that the high availability of the view controller should be redundant. The tool’s control and UI part should be improved and made more advanced. The feature that helps with the manual movement of tapes should also be improved."
"HPE StoreOnce should come with a detailed installation guide."
"We would like to see some improvements in the Veeam Backup & Replication integration. It's good, but it has a lot of room to improve. In particular around the inability to easily move data between StoreOnce appliances."
"We're outsourced with a partner who recalls a larger amount of problems with the stability of the product."
"One item I wanted to see is SSD drives as a cache, and that was, for a time, still lacking in StoreOnce, however, they have done it now. It's not available yet, however, it will be shortly."
"I would like to see an emphasis placed on making data deduplication and compression more powerful."
"While StoreOnce has many features, it needs to focus on integrating with third-party backup software solutions."
 

Pricing and Cost Advice

"The licensing costs and pricing model are based on capacity and the license is easy to upgrade."
"The solution is more affordable than other vendors."
"The product is offered at a very competitive price in the market."
"We offer monthly or yearly subscriptions. The price could be cheaper."
"Dell PowerProtect Data Manager is not an expensive solution."
"The solution is not less expensive than competitors but pricing deals are available."
"The price of Dell EMC PowerProtect Data Manager is reasonable."
"We have got a perpetual license, and we have access to all the features. If you are using cloud banks, you can store the internal data in HPE Cloud if needed. You can offload the data to the HPE Cloud. It is a licensed product. We have got around 10 TB of cloud bank storage with a one-time payment. We specifically took 10 TB for very critical offsite backups. We can also increase it in blocks if needed."
"The licensing costs is capacity-based and come bundled with support."
"The solution is pretty expensive."
"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."
"The price puts me off. It's definitely on the high side."
"The licensing schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."
"I rate the platform's pricing a seven out of ten."
"The product is not expensive. It is available at a good price."
