I'd easily recommend ownCloud to small businesses or teams within organizations. I've not used ownCloud in large deployments, so I'd hesitate before suggesting it in a situation where more than 10 users need support. That said, ownCloud is easy to set up and multiple instances could be used to service a large user base.
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.
Attention and dedication to making the product a world class product with continual product updates.
Ease of use from an administration standpoint, and a very Clear UI.
The price -- you can't beat free!
Mobile applications are great.
Integration with public S3 cloud providers like AWS S3 and Wasabi S3.
2FA authentication is supported and works great!
Marketplace Add-Ons: I love this! For example, I can install an add-on that natively opens raw images. I am a photographer as well, and being able to quickly view the CR2 Raw Files direct from the camera is fantastic! This was made possible by a marketplace add-in.
Embedded Media Players: Photos, Music, and Video files can be viewed and played right in the browser window.
Sync application to keep local files on a computer updated with the files on the server.
Access control and permissions -- shareable links!
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.
Inability to easily collaboratively edit the same document by several people. Some advances have been made with Collabora (Libreoffice online) but it is still very sub-par compared to Office365 and desktop/online Office editing Sharepoint or OneDrive documents.
Apps for Calendar and Contacts are not part of the basic core, and although now quite supported they cannot still be easily deployed in common email clients such as Outlook or Thunderbird, separate CalDAV and CardDAV plugins need to be installed. Embedding an email solution and plugins for major email clients so they can work just by entering username and password would be good.
Risk of moving important folders/files to another location just by random drag-and-drop on Windows. Sometimes this breaks public links that cannot be restored anymore. Reverting such mistake by any of the users is impossible automatically.
When some user deletes some data in a shared folder it is put into recycle bin of the owner of the folder. The user who deleted cannot himself/herself revert such action as he/she does not see the recycle bin (trash) of the owner. Also, there is no log in the recycle bin who deleted that file or folder.
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.
It provides us with great ROI compared with other solutions. It is also a versatile product, having NAS and SAN product lines depending on the business requirement. Furthermore, the implementation of dual controller lines would allow us to consider it for more critical applications to supplement the more enterprise-level SAN solution. It also is a wonderful backup solution, having all the applications available after purchase of the appliance without the further need to purchase additional software or licensing.
OwnCloud is easy for me to use, and I believe it would be for others too. The barrier for most people will be the set up. For a technology professional like myself, ownCloud's setup is pretty straightforward, but it's not the sort of thing most casual users will be able to handle. Also, it's on the user to maintain the service. These can be taken care of by paying someone to do it for you.
The Synology DiskStation is fairly easy to use, but maybe a challenge for those who not super IT savvy. With some trial and error, you can pretty much figure out how to configure the NAS the way you want it configured. I would say it is easy to use once it is set up and maintaining the device is likewise pretty straightforward as well.
Compared with other cloud services, ownCloud has been the most efficient. It doesn't create a noticeable drain on resources and very quickly syncs across all my devices. I'm usually able to save a file on my laptop and by the time I walk over and sit down at my desktop machine, it's already there. I don't need to wait as often as I have with services like OneDrive.
Regarding the community edition, there is a reasonably good support on the IRC, forums and in the issue section on Github. Perhaps a much more individual approach would be available if the premium support was chosen and the instance of the server was provided by the Owncloud company that also offers some premium extensions, not available generally. However, we did not need this level of support yet.
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.
The paid cloud services are expensive if you need a lot of data. You're giving your personal and business information to a data-hungry organization. Local NAS solutions are too slow. We run ownCloud on an older business PC and the performance is outstanding, even for remote access, due to local syncing.
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.
It has helped us go from printing things out to file them away to going 100% digital with our files and documents because we have a secure place to save stuff.
We are organized. I can't really put a value or number to how amazing this is for us, but when we deal with so many documents and files it can be so hard to keep things organized, but with Synology DiskStation, we have all our files in specific places and it helps us stay organized and definitely saves time because things are so easy to find.
One negative thing has been that our Synology DiskStation relies on us either being plugged into the network in the office or having a strong internet connection at home. With the pandemic and everyone working from home, we have had "outages" where we were not able to sync our data, and things were lost and we had to start over.
