Andrea Zanonepoma

Engineer at a renewables & environment company with 51-200 employees

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.

Pros

"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."

"Reverse Delta is Altaro proprietary backup deduplication technology. With Reverse Delta, the latest version of a file is always made available in its entirety, not as a delta file."

"The product has many valuable features for handling backup needs, including replication, live migration, and incremental disaster recovery."

"We use the latest feature in Altaro called CDP (Continuous Data Protection) to back up our VMs as often as every five minutes. It allows us to make sure no data is accidentally deleted or overwritten."

"The ability to test the backups without having to manually mount the VHDs after restore allows us to check the integrity of the backups."

"The initial setup was simple and easy. Anyone without prior experience can install, configure, and use it."

"The intuitive interface allows you to set up and perform backups and restores easily."

"Valuable features for us include quick recovery, compression, and deduplication."

"This solution is stable."

Cons

"The backup of the Mac OS solution in Datto SIRIS doesn't exist at this moment."

"Hornetsecurity Altaro VM Backup could be improved in several areas, such as enhancing scalability features and possibly reducing the price."

"Stability."

"The initial set up was complex, and I was not able to do the set up myself."

"The scalability of the solution is limited."

"Replication is not fast, the GUI could be more user-friendly, and technical support is lacking in Iran."
