Cost savings and efficient decompression but needs better cloud integration
Our primary use case for Arcserve UDP is its decompression feature, which helped us save money by reducing storage needs. Despite moving to cloud applications, we have been using Arcserve UDP for backup and disaster recovery Arcserve UDP has helped our organization save considerable amounts of…

Has reduced downtime by enabling fast recovery after ransomware incidents
The facility to use Datto SIRIS is a function that I prefer. The user interface of Datto SIRIS is very simple and very user-friendly. The restore is very fast. The alerts that arrive in my email are very complete. Reporting in Datto SIRIS is very efficient. The reporting via email from Datto SIRIS for me, my customer, and my team shows that every single backup is okay or if there is a problem because the snapshot for the server is broken or another problem that I can address systematically. 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 cost for Datto SIRIS is very important. Using Datto SIRIS notably reduces time and introduces high-level security. Datto SIRIS positively impacts my organization by reducing downtime for the restore. The restore with Datto SIRIS is very fast compared to other solutions that I know.

Quotes from Members

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

Pros

"Our customers are happy with the product’s functionality."
"It is very stable."
"The most valuable feature of Arcserve UDP is its decompression capability."
"The ROI is very good because of the speed of the backup."
"The most valuable feature of Arcserve UDP is the initiative UI and the logs are clear and detailed that are generated when there has been an issue or failure on the user's system. We only have to log onto the client's system to retrieve the information. It is possible to precisely identify the problem's location. The system categorizes and logs every step in a structured manner, selectively displaying only the essential logs. However, to view a comprehensive log, one must access the line machine log and examine the actual client for detailed logging."
"The most valuable feature of StorageCraft ShadowProtect is the speed and the compression of the backups. The compressed backed-up files do not take up as much storage. Additionally, the incremental backups can be done in one minute and be backed up on a disc very fast."
"The recovery part of the product is very good."
"I like the tool's speed."
"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."
 

Cons

"Arcserve UDP is in the middle range of complexity. The interface can be developed a little bit more to be user-friendly."
"The speed of restores should be improved. We have found the speed of large restores rather slow."
"The solution could improve by being more user-friendly. It can be difficult to assign destinations and choose which files and folders we need to back up. There are some aspects that are unclear."
"Every time I change the disc, I have to do a full backup."
"I think that the price could still be a bit cheaper and I do not like that they have been purchased by Arcserve."
"It takes much time to verify and consolidate images for backups."
"We are looking at scaling up to the cloud and using immutable copies on the cloud. Arcserve UDP 8.0 does have the immutable feature supporting AWS, but I'm looking for multi-cloud support. So, I'm waiting for Arcserve to release that in the next release."
"Based on my experience, whenever we need support, there are difficulties with communication when trying to resolve the issue."
"The backup of the Mac OS solution in Datto SIRIS doesn't exist at this moment."
 

Pricing and Cost Advice

"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."
"I rate the product price a five on a scale of one to ten, where one is low price and ten is high price."
"I feel that the product is fairly priced."
"The solution is very expensive."
"The price of this product is high and it should be lower."
"The price of StorageCraft ShadowProtect is competitive in the market."
"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."
