It's a high-level solution, and the price is correct for me.

Andrea Zanonepoma

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

Unified data protection has simplified hybrid backups and has improved ransomware recovery speed

Commvault Cloud's best feature in terms of protection is that it provides data protection and accomplishes its job effectively. It offers a unified approach to backup across all environments, including on-premises, public cloud, and SaaS applications such as M365 and Salesforce. I also use it for virtual machines and databases. The unified protection approach helps my team manage different environments effectively. Before Commvault Cloud, I used a separate VM backup tool to protect the VMware environment. For database backup, I had to use the native tool or backup scripts. For the cloud part, I had to use the native AWS or Azure cloud tools. After moving to Commvault Cloud, a single policy or a set of backup policies is applied across virtual machines, databases, workloads, and cloud workloads. I can protect my environments, which reduces manual configuration errors. Regarding visibility, it provides one dashboard to manage and centralize monitoring of all workloads. It is very easy to track backup success or failure. I can see the SLA compliance and storage usage without needing to jump between tools to check or have visibility of it. Regarding the recovery experience, the recovery time has been reduced drastically by using Commvault Cloud. It has simplified cloud management and provides easier manageability to manage retention policies, encryption policies, and compliance rules. This helps reduce operational workloads. Commvault Cloud has impacted me very positively. It simplifies and unifies data protection across hybrid workloads. Instead of managing multiple backup tools for virtual machines, databases, and SaaS applications, I now have a single platform with consistent policies and centralized visibility. This has really reduced my operational complexity and improved backup reliability. Regarding the cyber resiliency posture, the immutable backups and ransomware recovery workflow give me greater confidence in recovering quicker from potential risks. Commvault Cloud has positively impacted me in several key areas: unified backup management across environments, reduced operational overhead, improved ransomware resiliency, faster recovery times, better visibility for compliance, and easier management of hybrid or cloud workloads.

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.
