I rated the scalability as seven because even though the solution can scale, load balancing must be done manually, as it's not automated.

Room For Improvement

Azure Site Recovery needs better integration, deployment, stability, security, and support, with improved logging, pricing, and platform compatibility.

Nasuni struggles with cloud integration, performance, and user experience, needing improvements in data retention, security, and analytics.

If their agent version is mismatched and the health status is critical, you will not be able to perform your Azure Site Recovery.

I suggest Nasuni improve their syslog forwarders to support TCP protocol, as it's more secure than UDP, which is plain text and not protected at all.

Long-term user praises cost savings and reliability of disaster recovery solutions

IT Manager at NTT DATA

There is only one thing to note: the agent has to be up-to-date when SCCM or any third-party tools are doing patching activities. If their agent version is mismatched and the health status is critical, you will not be able to perform your Azure Site Recovery. Recently, I worked with a mass issue related to Recovery Services Vault, and the VM support engineers are taking a lot of time to extend support to the customer. When you raise a call, they wait too long, and even if you request an engineer to set up a call for severity B cases, they are not ready to communicate over the phone, preferring email instead.

Reviews from Real Users

James J., IT Manager at a marketing services firm, says Nasuni’s management dashboard is helpful because he's able to view all of the different filers at once rather than check each one of them individually. He values the software’s security, reliability, good performance, helpful alerting, and responsive support.

According to a Server Engineering Services Lead at a mining and metals company, Nasuni offers good OR and DR capabilities, performs well, offers data security, and continuous file versioning helps recover from hardware failures.

The Managing Director of IT at a construction company appreciates Nasuni because it eliminates a lot of work that was previously done when managing backing up and restoring data files.
