Sergio Itikawa - PeerSpot reviewer
Software Solutions Architect at SPEData
Has supported hybrid IT environments effectively and offers strong data protection
With Arcserve UDP, the most valuable feature is to improve persistent data, which I consider important. I use other products too, not only Arcserve UDP, as we use TrueNAS as well. Arcserve UDP improves the precision of data. I have utilized Arcserve UDP's data deduplication feature, and the data deduplication feature helps my storage efficiency significantly. I have used Arcserve UDP's continuous data protection. It is beneficial for operational continuity because we use it constantly and have no objections to Arcserve UDP technology; I think it is very good. Arcserve UDP's integration with multiple operating systems is very good and very efficient. This brings value for me since many of my clients have different operating systems like Windows and Linux; there is no problem. Regarding the deduplication and compression with Arcserve UDP, I think Arcserve UDP is still a solid solution that we primarily use.

Reliable backups have protected email and servers and now enable rapid ransomware recovery
For the smaller Datto SIRIS devices that are made for backing up one or maybe two different machines, adding more RAM and giving it a better CPU would be phenomenal. Sometimes when dealing with entry-level Datto SIRIS products, you face an issue depending on how much storage there is on there when it's trying to parse through all of the data. It takes a while, and when it comes to data recovery, time is everything. Datto SIRIS should remove the ability to set it up as a NAS-based file share operation system. It seems counterintuitive for something that is made for immutable storage that is walled off so that it can't be destroyed to be allowed to be a local centralized file share that individuals have access to. This seems to be begging for a mishap. Datto SIRIS will require some maintenance when the hard drive gets past 50% capacity, which is Datto's statement on the capacity. You should never use past 50% of the storage locally. Then you have to reach out to Datto directly to get an external hard drive to transfer files to send off the data for it to be shot up to the cloud. We've had a couple of instances of devices not uploading to the cloud because either they were too full or there were failures in certain parts of the file upload to the cloud, which put it into a circle of death where it just kept trying to do the same thing over and over again and had to request assistance from Datto in those situations. Otherwise, if you store it in a dusty cabinet, you have to spray it with a computer duster every once in a while.

Quotes from Members

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

Pros

"Easy restoration and the solution works quickly."
"This product is extremely user-friendly and it is capable of performing large-scale archive/backup (five+ years worth). It is easy to store, maintain, and check backups."
"The data protection functionality is the most valuable feature of this solution."
"The solution has no limitations because it does backup for Linux and Windows."
"The most valuable features of this solution are that I can by just one click, copy and paste anything that I would want. I do not have to restore the whole virtual machine."
"The ROI is very good because of the speed of the backup."
"Arcserve UDP has a good configuration and user interface. It makes the job of an administrator easy."
"It allows us to back up all the servers and centrally manage them."
"Instant Virtualization is the best feature of Datto SIRIS that we have liked so far, as it allows us to boot servers in minutes during outages."
"Datto SIRIS works out of the box and it is a key feature that we really appreciate."
"Datto SIRIS has changed my recovery time objectives significantly, as it is excellent, taking minimal time, with a simple and smoother interface that allows for a shorter backup process compared to other applications I have used, such as Commvault."
"Datto SIRIS has positively impacted my organization by drastically reducing downtime, with recovery from server failures now taking just five to ten minutes."
"Since I started using Datto SIRIS, the time to recover data or servers has improved significantly; before, restoring a file or server was very long with the normal backup system, Datto reduced the time much more when I needed to recover a file or a machine."
"The effectiveness of Datto SIRIS in ransomware recovery is fantastic; I would say it's the best, hands down."
"Previously, three hours were spent on troubleshooting and everything, but now with Datto SIRIS, issues are resolved in half an hour or less."
"The best feature of Datto SIRIS is that we are just two clicks away from remoting into the client environment, and we can fetch all the information in one place."
 

Cons

"It takes much time to verify and consolidate images for backups."
"One area for improvement in Arcserve UDP is its capability to interact with other cloud servers."
"It should be easier to switch between backup locations. We have multiple data storage locations and sometimes one of those storages need to be replaced. It would be nice if they made it easier to reconfigure the backup configuration."
"In the most recent version of premium plus the replication has been removed, and it should re-added to the solution."
"We cannot restore each user's mailbox. Each user's mailbox should be independently restorable. Also, this solution is very slow. If you select all of the servers, it runs for a long time... It needs to be faster. Finally, If anything happens to one server we should be able to switch to another server."
"The product is not user-friendly."
"The tool doesn't provide cloud integration in India."
"Arcserve UDP is in the middle range of complexity. The interface can be developed a little bit more to be user-friendly."
"I have not seen any reduction in disaster recovery testing hours from Datto SIRIS."
"The pricing offered to MSPs for Datto SIRIS is okay, but the ability for MSPs, their upcharge when it comes down to small, medium businesses, SMB clients, is actually putting Datto out of the market for SMB clients, especially with the ability to purchase Dropbox and all these cloud-based storage solutions now."
"The backup of the Mac OS solution in Datto SIRIS doesn't exist at this moment."
"I was disappointed with the processing power and the storage capacity of the ALTO 5 device. Within two weeks of deploying it, I was getting emails that I need to upgrade it."
"For improvements in Datto SIRIS, I would suggest enhancing large-scale virtualization performance and providing more transparent pricing, as that is often complex for MSPs and end customers."
"The cost is higher compared to other platforms in the market like Veeam or Acronis."
"In my opinion about Datto SIRIS, areas for improvement include increasing speed in recovery processes and strengthening security to enhance the product's overall effectiveness in backup and disaster management."
 

Pricing and Cost Advice

"I do not work with the pricing or licensing issues of the solution for our organization."
"It is a bit pricey, considering the reliability problems. If the tool worked flawlessly, the price would be fair, even cheap."
"We only have the maintenance of three standard UDP licenses. Each license is 50 Euro. There are some additional costs for the storage and software but it has nothing to do with the UDP."
"The solution is priced well compared to other solutions."
"It is approximately $400 to purchase a virtual service outright."
"Its price seems reasonable. Its price is average as compared to the other products I've looked at. We have a three-year license right now. There are no other costs beyond the standard licensing fee."
"The pricing is moderate."
"The retail fee is $1300 for a year for one server. Other than that, there is just the cost of your hardware."
