Has provided strong data protection and unified access while streamlining backup operations
Cohesity Data Cloud is not unique in this area. There are a couple of other vendors who are playing in the same area. They provide some sort of isolation for the protected data that makes it very difficult, almost impossible to tamper with once it is stored on the platform. One of the major issues of ransomware attacks is that they happen in the background and it is too late after being hit. Giving a hard time for bad actors to access the data provides more immunity for your data from ransomware attacks. All organizations are very interested in as-a-service model where they do not pay upfront costs, but only get the services and pay for what they use. Converting from CapEx to OpEx is the ultimate goal for any financial manager in any organization. The model uses some sort of object storage for the backup data and contents, which gives a better level of safety than the traditional file system because normally the object storage is not subject to alteration. The only concern I have with cloud implementation is that if you have a presence on-premises, trying to use the cloud may become a performance challenge. It is a perfect situation for workloads that live in the cloud. The way I design things is we should not send data across the WAN to the cloud if it is a large volume that could potentially affect performance. A cloud solution is ideal for a cloud workload from Cohesity Data Cloud perspective. It is best to have some sort of local presence of a repository to do the backup using LAN performance. Then we can always send or upload the data to the cloud without impacting the actual backup window. Support for additional platforms and the option to do multi-tier performance would be beneficial. For example, if I have three types of workloads - SAP database, Oracle database, and SQL database - each with different backup window requirements, the ability to tier performance to meet these specific needs would be perfect for the actual workload and meeting the availability requirements of each application domain. The general perception is if it is not broken, do not fix it. In most cases, organizations do not see value for security until they are hit with something bad. With ever-increasing threats and risks of ransomware and data theft, the problem is becoming more obvious. Looking at what is happening in the market and seeing organizations being hit by security threats, the level of loss of services and client dissatisfaction makes security investment worthwhile. There is no real tangible ROI for security, but considering the potential of losing data forever or having it exposed unnecessarily to the market, it is worth the investment. The bad actors and risks are always reinventing themselves, so we must reinvent our security posture.

A reliable and user-friendly solution for effective backup, storage, and multimedia needs
In terms of scalability, I would currently rate it an eight out of ten due to its aging nature. While I don't have access to all the latest features available on more recent devices, at the time of purchase, considering its capabilities then, I would have given it a solid ten.

Quotes from Members

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

Pros

"Its big data and archive data features are the features that I have found most valuable, and I can use it in a big virtual environment."
"It has excellent integration for virtualization, which means we can easily protect VMs, virtual machines, which consists mainly of snapshot backups that are quite easy to recover."
"Now I have got one platform that is doing my backup to disc, it is doing my data protection, it is doing my cloud archive, and it is doing my NAS protection."
"The clone feature is very nice. You can restore workloads onto Cohesity's storage, which is also nice to have when you don't have enough space to restore on the server."
"Cohesity Data Cloud comes with a different flavor where they provide global deduplication across multiple platforms, which provides a tremendous return on investment from a storage perspective because if you have a segment that can be deduplicated in one box and you have multiple boxes, you cannot repeat the deduplication function across different hardware."
"I find the most important feature to be data protection."
"It's very regimented and fast. It does local backup, cloud backup, long-term coverage, and disaster recovery."
"Cohesity Data Cloud is user-friendly, and anyone can use this tool; the support is really good, especially the web support, and the dashboard and everything are good."
"The most valuable features of Synology DSM are its security and connectivity."
"The product performs well. It is easy to use and implement."
"Synology DSM is very easy to work and operate."
"The most valuable features are the basic storage, file management, Btrfs file system, and built-in backups that come with the solution."
"The solution's most valuable feature stems from its ease of use, making it the tool's most interesting part."
"The most valuable feature of the solution is that it serves as a backup for our company's virtual machine."
"The most valuable aspect is its ability to handle multiple disks."
"It offers a variety of software options through its package center, allowing users to customize their NAS device to serve multiple purposes."
 

Cons

"The primary drawback is the need to transfer large amounts of data to the cloud via an internet connection, requiring significant bandwidth."
"The only concern I have with cloud implementation is that if you have a presence on-premises, trying to use the cloud may become a performance challenge."
"The initial setup can be complex, depending on the environment."
"Sometimes the support team does not provide proper assistance during critical issues from the cloud end."
"The downside of Cohesity Data Cloud is that it is not supporting a legacy environment."
"Their documentation portal is not up to date for newer releases and I strongly recommend Cohesity to increase their efforts on the documentation portal."
"There is limited support for legacy systems, which is something that could be improved."
"It has never been touted as a tier-one storage platform, and that would be a benefit. They are currently working on solving that issue."
"One area where Synology DSM could improve is in enhancing its ability to detect and respond to security threats during backups and replication."
"The only bothersome aspect is that the device is aging."
"The platform could be much more cost-effective and flexible for integrating third-party products."
"The product's only shortcoming is pricing, as it is an expensive solution."
"Users may lose their data if they don't configure the solution properly."
"Synology DSM's user interface is not quite intuitive."
"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."
"Even though Synology provides a backup solution, it does not recognize the VM movement across cluster hosts."
 

Pricing and Cost Advice

"Regarding pricing, it's very costly and I rate it a four."
"Competing products sometimes use deceptive marketing to make their products seem a lot cheaper. Comparing apples-to-apples, DataPlatform wins out."
"It's priced properly for the market."
"The price of the solution is very good."
"Synology DSM is a free tool."
"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."
