By using Azure Backup, you can back up your NAS device you use locally as a file server, virtual machines you use in [a] production environment, critical databases, and everything you can think of. I do not know if there are scenarios that are not suitable, it meets all my needs.
OwnCloud/Nextcloud is a great application for cloud storage of files, and makes sharing specific files or folders easy and fast. It also makes a great tool for real-time collaboration, including real-time chat and simultaneous editing of documents or spreadsheets. I have used ownCloud to assist clients in sending large files that could not be emailed -- for example, one of my clients is a Video Production agency. They produced a commercial to air, but could not email the file as it was 400MB. OwncCloud came to the rescue. I set up a temporary share and allowed him access to upload into that folder. Once the file was in the folder, I generated a share link that was then forwarded to TV stations for instant viewing in a browser. Each TV station then downloaded it and was able to add it to their scheduling system quickly. From the Photography side... I am able to deliver large amounts of files quickly and easily to my clients, and they can download or view on mobile devices easily. Since I use ownCloud on a daily basis, I cannot think of any reason why I would not use this software
Azure Backup is fast! Coupled with the fact that Microsoft created Azure and Windows - these two operate phenomenally together!
Administering the backups inside of Azure is a breeze. The ability to mount, restore entire backups, or recover files, has been made very easy. You do not have to download any media to recover something, you do this all in the cloud and it gets mounted in Microsoft's systems. Making this process less than a quarter of the time you would have spent with your 'other' backup solutions.
Backup vaults should ask if you want to send notifications when you first set it up, there have been a couple of times when I noticed a month later that, backup job failures were not configured to send email notifications.
Azure backup is easy to implement, accessible by using the web portal GUI, and has the ability to restore at the file level or the complete VM. We have experienced zero issues with the backup process or performing file-level restorations. We have not restored an entire VM to date.
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.
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.
One of the differentials of the solution is the high level of guarantee and support of the Azure Backup solution. Microsoft is a reference in a technology company with a highly trained support team and helps us with any questions or technical problems with the tool. Service is fast and efficient with trained engineers.
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.
The cost, not only in the short term, but in our long-term calculations.
Even in need of improvements, the pre-sale and post-sale support is very good.
The ease, like many Microsoft products about scheduling backups, the friendly interface, the fact that there is no need for an expensive resource dedicated to this backup and some other details, made us choose Azure Backup.
ownCloud is better than Google Drive and Microsoft's OneDrive. I have not used Google Drive in some time now, so it may have improved. OneDrive has become better over time too, but my go-to is still ownCloud. Firstly, I prefer to have my data under my control. No other service can offer the level of control that ownCloud does. Setting that aside, in my experience Google Drive never quite got syncing right. Unless you have a very small collection of files and you're not synced across many devices, Google Drive fails to achieve a complete sync. The icon is always showing that Drive is syncing (and not up to date). I've had similar issues with OneDrive, but these days on Windows 10 OneDrive usually can achieve a complete sync across multiple devices, but it often hogs CPU and Network resources to do so, and it's still slower than OneDrive.
The company grew from 4 employees in 2013 when ownCloud was initially deployed to about 40 in 2017 and still using it with a very similar setting without any major upgrade on the same Linux VPS. 95% of all company data are stored and shared via ownCloud successfully. No clear data about ROI but clearly the perfect adoption rate by all people and its ubiquitous use makes it an essential part of the company workflow.
