We transitioned from a standard Windows File Server. This solution is much cheaper. Easy to use and extremely reliable. We will be replacing our two Synology boxes in 2020 with newer versions.
Windows Server is the only one that has an upfront cost for licensing before hardware is considered. Windows Server is generally better suited for multi-faceted approaches; however, for just backups, TrueNAS and Synology are cheaper and just as good. For standalone services …
The Synology DiskStation is well suited as a NAS solution, easy enough to mirror a Windows file server shares setup. Access to the Hyperbackup utility eliminates the need to purchase a tape backup solution. A portable USB drive can be used as the initial backup target. For air gap purposes can connect Hyperbackup to the various cloud providers such as AWS, Azure, GCP to copy backup data there. Utilizing it as a backup solution has also been great, instead of purchasing a tape solution, tapes and an offsite tape repository. Active Backup for Business is another excellent backup utility for physical servers, VMWare virtual machines, etc. Restoring files is fairly intuitive. Until Synology introduced the dual controller setup, using it as a SAN was less appropriate as there was occasional downtime when the controller had an issue but this was less important for the scenarios we were using it for. It would be more of a concern if we had used it for things that require more robust uptime requirements. Overall we are happy with the features of the Synology DiskStation.
Windows Server and Active Directory is very robust and stable, it has been a staple in every IT environment I have worked in during my career. Junior to Intermediate admins can learn Windows Server easily, the user interfaces make administration tasks very easy as well as the documentation available through a vast amount of resources. There are other Operating Systems available with no GUI which has a smaller attack surface, faster update installation and reboot time. Windows Server does have the ability to remove the desktop experience, however it is not something I have had experience with and I believe most administrators choose not to remove it.
Synology DiskStation offers lots of options for creating links to share files or request that some uploads files. It makes it really easy to just share a link that can have an expiration or a set number of times it is accessed.
We always had enough storage on our Synology DiskStation, we never had to worry about something being too big to upload or share.
Love how you can create folders that are shared and also have some that are private. This makes it so easy to have shared collaborations with coworkers or clients, but also allows you to have a private place to save things that only you need.
While BTRFS is a more advanced file system than ext4, it also is in a perpetual state of development, with many features not fully functional and a plethora of bugs. Synology has managed to overcome many of these limitations by placing BTRFS on top of a LVM, but there are much better file systems that Synology could have used, such as OpenZFS.
DSM's built-in backup software, HyperBackup, while robust, oftentimes runs into issues. Specifically, backups can be working fine for months or years, and then suddenly the backups will fail. Sometimes these failures can be resolved, but oftentimes the backups need to be completely restarted. Fortunately, even when the backup fails, the existing backups are still accessible, it is just that new backups can not be performed.
The underlying Linux OS provides significant benefits, but also adds a fair amount of complexity. Most of that complexity is wonderfully hidden by the DSM interface, but when certain problems arise, delving into the Linux command line is not out of the question.
Perhaps the biggest issue with Synology DiskStation is Synology's support. The issue isn't that the support is bad, but it can be frustratingly slow when dealing with a major issue. Synology does have a very active community that is always willing to help, but nothing beats first-party support.
Microsoft needs to minimize the update frequency by making the product more secure. It can become very exhausting trying to keep updated if you don't have a dedicated support team. It can become challenging where the business is unable to allow downtime for reboots as part of the update process.
Prone to security and audit vulnerabilities.
The operating system needs more CPU and memory resources compared to other options such as Linux.
Understanding the licensing model can be abit confusing.
Comes with a standard firewall, but not the most secured one available. Would suggest using a more secured firewall as part of your antivirus software.
Due to the number of vulnerabilities and the operating system being a target for hackers, anti-virus software is a must.
As long as Synology give us support for our hard drivers we will not change. I know Synology has now forced their hands to buy their own hard drivers and their new line of products. But if we still have support for old hard drivers from other manufacturers then we will still use Synology Nas. Otherwise we change manufacturers
I've carefully reviewed the servers and services currently running on Windows Server 2012, and given the opportunity would renew them as is going forward. There are two systems I currently have in place, one is a very large Linux implementation for a large ecommerce site, and one is a very large backup solution front ended by FTP servers running Linux. Neither are well suited for Windows, but the overall network infrastructure is and will be Windows Server for the foreseeable future.
The Synology DiskStation is easy to set up and manage. The interface is clean and features are well documented. These units are reliable and can be set up to do scheduled integrity checks so failures can be mitigated before they halt business operations. The available packages for expanded roles makes these devices versatile.
Anyone new to IT could easily use the familiar Desktop Experience (GUI) version because we all know how to use Windows, whether a client or server version. Once an IT user is more comfortable with the operating system, they can move on to the Core version, which is the way to go in almost all situations.
Unfortunately, the one time I've had to reach out to DiskStation support, it did not go well. My NAS appliance wasn't appearing on the network, and no matter what the support team tried, they could not get it back online. Instead of offering to send me a new unit, they told me to go buy a new one - obviously, this was a disappointing response and not very eco-friendly either! Fortunately, through some internet research of my own, and some ingenuity, I figured out I could restore my NAS to factory settings by removing all the drives and resetting. Only then did I realize I had a bad disk. I had to experiment for a while to figure out which one it was. Once I had done that, though, I was able to get the latest DiskStation loaded back on, no thanks to the DiskStation support crew. If notifications were rock solid, I suspect I would have caught the bad disk before it because an OS problem, but I never received a bad-disk notification.
Microsoft's support is hugely wide-ranging from articles online to having to contact them directly for the more serious issues. In recent years when I have contacted them directly, I have found the support o be excellent as I have found myself connected to very knowledgeable people in the field in which I needed the support. The online support available is vast and I tend to find most of the time that there is always someone out there who has had the same issue as me in the past and knows something about how to resolve it! This is the advantage of using industry standard and long-established systems such as Windows Server.
Make sure that you have detailed processes in place for every server instance you plan to install/upgrade, if possible get the base OS loaded and Windows Updates applied ahead of time, and if using a VM take a snapshot prior to installing each role, as well as along the way.
Synology DiskStation packs a punch with the latest and greatest feature set which goes above and beyond many other vendors. It allows for a turn-key solution to cover almost every use case in the SMB market leaving other vendors behind.
They are different experiences, and while the other solutions offer enterprise-grade stability and, in some cases, address Windows server shortcomings (such as patching), they all do the trick, but the other solutions require a deeper technical background/configuration of items at the command line, which some people are not fully comfortable with.
