Leverage disaster recovery with reliable support and cost-effective future-proof features
Zerto is straightforward to implement because it only requires the installation of an agent on the VMs designated for migration. A service, typically a VM, must also be deployed at the disaster recovery location. This entire process is simple and can be completed within three days. Zerto's near-synchronous replication occurs every minute, allowing for highly granular recovery points. This means that even if interruptions or malware disruptions occur within that minute, Zerto can restore to the last known good state, effectively recovering the entire setup to the latest backup. This capability ensures high data security and minimizes potential data loss. One of the main benefits of implementing Zerto is its data compression, which significantly reduces the load on our IPsec VPN. Zerto compresses data by 80 percent before transmitting it across the VPN, minimizing the data transferred between geographically dispersed locations. This compression and subsequent decompression at the destination alleviate the strain on the VPN, preventing overload and ensuring efficient data synchronization. Zerto simplifies malware protection by integrating it into its disaster recovery and synchronization features. This comprehensive approach eliminates the need for separate antivirus setups in virtual machines and applications. It streamlines our security measures and removes the need for additional software or solutions, resulting in an excellent return on investment. Zerto's single-click recovery solution offers exceptional recovery speed. Through the user interface, a single click allows for a complete restoration from the most recent backup within two to three minutes, enabling rapid recovery and minimal downtime. Zerto's Recovery Time Objective is excellent. In the past, if a virtual machine crashed, we would recover it from a snapshot, which could take one to two hours. With Zerto, the recovery process takes only five minutes, and users are typically unaware of any disruption. This allows us to restore everything quickly and efficiently. Zerto has significantly reduced our downtime. When malware affects our data, Zerto immediately notifies us and helps us protect other applications, even those not yet implemented with Zerto. By monitoring these applications, we can quickly identify and address any potential malware spread, minimizing downtime across our systems. Zerto significantly reduces downtime and associated costs during disruptions. Our services are unified, so in the event of a disruption without Zerto, even a half-day disruption would necessitate offline procedures. This would lead to increased manpower, service delays, and substantial financial losses due to interrupted admissions and other critical processes. By unifying service processes, Zerto minimizes the impact of outages. Zerto streamlines our disaster recovery testing across multiple locations by enabling efficient failover testing without disrupting live services. Traditionally, DR testing required downtime of critical systems, but Zerto's replication and failover capabilities allow us to test in parallel with live operations. This non-disruptive approach ensures continuous service availability while validating our DR plan, even in scenarios like malware attacks, by creating a separate testing environment that mirrors the live setup. This comprehensive testing provides confidence in our ability to handle real-world incidents effectively. This saves us over 60 percent of the time. Zerto streamlines system administration tasks by automating many processes, thereby reducing the workload for multiple administrators. This allows them to focus on other university services that require attention and effectively reallocate support resources from automated tasks to those requiring more dedicated management. Zerto is used exclusively for our critical services, providing up to a 70 percent improvement in our IT resilience.

Reliable and cost-effective
One area where Synology DSM could improve is in enhancing its ability to detect and respond to security threats during backups and replication. Currently, it lacks the capability to automatically stop backups if it detects a virus or suspicious network activity, as some third-party solutions can. Having AI-driven analytics to identify anomalies and halt backups during potential attacks, along with notifications to administrators, would be valuable. Additionally, providing a dashboard for monitoring the backup environment's security would be a beneficial feature. These improvements would help address security concerns and make Synology more competitive in this aspect.

Quotes from Members

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

Pros

"Some of the most valuable features are the synchronous replication and migration with RDMs. I really like the conversion of RDM VMs for migration."
"We implemented Zerto because it is crucial for our organization, especially as we move into the cloud. We needed to ensure that we could retrieve data properly and migrate easily. The solution allows us to keep our users collaborating throughout the migration process, making it much quicker than our previous solution."
"Zerto's ease of use is outstanding; it's easy to set up and has a clear interface and menus. The reporting, analytics, and online monitoring are also excellent."
"The replication and recovery features are the most valuable... On two occasions, other departments in our organization reported issues with specific virtual machines. We used the checkpoint feature of the Zerto to enable the recovery of those machines to a point that was a few minutes prior to the problem."
"HPE Zerto Software's continuous data protection or CDP is critical for our organization because it allows us to recover within seconds to minutes, and the journal allows us to pick a point-in-time recovery."
"The ability to test which virtual machines can be failed over to our DR site without interruption of our production environment."
"We have kept renewing Zerto because it seems to get better."
"The stability is great; there's very little downtime. I don't have to worry that there will be a surprise update to one of the ZVRAs or the host that I have to contend with. We're given plenty of notice to plan ahead for an update. As far as losing service and downtime, we haven't had that happen."
"The most valuable features are the basic storage, file management, Btrfs file system, and built-in backups that come with the solution."
"It offers a variety of software options through its package center, allowing users to customize their NAS device to serve multiple purposes."
"The most valuable features of Synology DSM are its security and connectivity."
"Because of its simplicity and the wide array of features it offers, I would recommend DSM for both tech-savvy individuals and those who prefer a straightforward file-serving solution."
"The most valuable aspect is its ability to handle multiple disks."
"The most valuable feature of the solution is that it serves as a backup for our company's virtual machine."
"The solution's most valuable feature stems from its ease of use, making it the tool's most interesting part."
"The product performs well. It is easy to use and implement."
 

Cons

"The only thing I could suggest for HPE Zerto Software would be better support for detached drives in a clustered environment, as it's currently not supported very well unless everything's running on a virtualized VMDK file."
"When we are trying to upgrade any virtual machines, we have to stop the virtual machines that have been replicated in Zerto and then upgrade or update to the virtual machines onsite. Instead of having to do it manually, there should be some way of automating that particular function."
"I would like Zerto to enhance the continuous backup aspect."
"It took me a little bit of time to get used to Zerto's terminology and to relate it back to how you do a backup traditionally. It was a little different. It took a little while to understand what a VPG is and what it does. That's an area that they could probably improve on a little, making the documentation easier to understand."
"To improve HPE Zerto Software, it would be helpful to make it more affordable."
"If we have multiple VMs in a VPG (Virtual Protected Group) and one VM is hung for DR, it holds things up. The only alternative is to create multiple VPGs. It would be nice to have one VPG where, if one VM is failing, it does not impact the overall process."
"We do have some sites that are very low-bandwidth sites. Zerto is able to set throttling in the solution, but the throttling is set at a site-wide level. In those instances that have very low bandwidth, I can't reduce the throttling on that site. It would be nice if there were a way to control the throttling by the protection group for a specific workload."
"The limitation with Zerto is that you're required to have one Zerto Manager per virtual center, and this means that you're only able to replicate one way. Technical support for this product was fantastic, before they were acquired by HP. You're now able to tell that the company is becoming too big, in terms of the support they provide."
"The product's only shortcoming is pricing, as it is an expensive solution."
"There's a surveillance application that allows you to connect IP cameras and stream footage to Synology and it is a great feature, but it's not always clear that adding more cameras may require purchasing additional licenses."
"Users may lose their data if they don't configure the solution properly."
"Synology DSM's user interface is not quite intuitive."
"Even though Synology provides a backup solution, it does not recognize the VM movement across cluster hosts."
"The platform could be much more cost-effective and flexible for integrating third-party products."
"One area where Synology DSM could improve is in enhancing its ability to detect and respond to security threats during backups and replication."
"Synology DSM is a good enough solution for small and medium companies, but I have not seen a big configuration of the solution for a big organization."
 

Pricing and Cost Advice

"If it were easier to license, and to scale it out a little bit more economically, that'd be a godsend. At the end of the day, my druthers would be to have all 200 of our servers protected by this platform. But for a company our size, that stretches our IT budget and it just doesn't make economic sense."
"I've been told that when they originally got the quote, it was a little bit of a sticker shock. However, now that we've actually been using it for six months, I've been told that the investment was well worth it."
"Its price is reasonable. I have not worked with other tools, but as compared to its competitors such as VMware, its price is lower. So, in my opinion, its price is good."
"Zerto is not cheap but is an invaluable asset."
"I do not have anything to compare it to. It is expensive, but I am not going to squabble about the price when I bring the system up in a disaster. It is what it is."
"We subscribe to their annual license package and we have tier one support with them."
"It's expensive, for sure, but for us, it comes down to the fact that we do not replicate our entire environment using Zerto. We replicate the mission-critical servers and services, so the yearly cost of Zerto is heavily outweighed by the potential cost of an outage."
"Zerto is a little bit on the higher side in terms of pricing. It would be better if they had a pay-as-you-go package."
"The pricing varies widely, catering to a broad range of needs."
"The price of the solution is very good."
"It is quite an affordable solution."
"The solution’s pricing is neither cheap nor expensive."
"Synology DSM is a free tool."
"Synology DSM is a cheap solution."
"The licensing part of the solution is free. The hardware is more expensive than the other solutions in the market, but it's okay in the long run."
