Nextcloud

Kommentare: From a simplistic view, having company reference material available on both laptop and mobile devices is key to our teams success. Nextcloud allows us to arrange the data in a way that fits our needs, not how the app wants it.
Flexibility - Within hours of a users request, we can have a new "feature" implemented. As a simple example, one of our consultants suggested having field data (draft source, notes, pseudo code, proposed architectural designs, etc) available as they are generated in the field. With just a simple directory structure and defining the parent app, we now have real-time data from draft designs that allows early collaboration.

Vorteile: Free, open source, versatile.
After years of paying for data sharing and collaboration tools, Nextcloud provides these (and more) features while allowing our company to "own" the files. The data never leaves our private network, which these days is more important than ever.
For less than the cost of a one month subscription to our old plan, our company purchased all the hardware needed to stand-up a Nextcloud Server that we control. Sure, there are some small monthly costs associated with maintaining the server, archiving backups, and performing updates, but it's small in comparison to the security and reliability of keeping our data on site.

Nachteile: Although there's considerable documentation, we experienced a few quirks during installation and deployment. Some are likely a result of our specific system configuration, but overall these were small and with a little internet searching, were quickly resolved

Vorteile: It was an easy PHP web app to setup that is fairly extensible. It has a large selection of plugins that let you add basically all functionality you’ll need to parallel something like DropBox Enterprise. I have only used the self-hosted version, so I can only speak to that, but so far, it has been fairly stable, running on an 8core 12GB VM with Ubuntu 18.04 (past 6 months) and Ubuntu 14.04 (for the past 3-4 years). Given that it’s self-hosted though, you’ll get no official support, except from the community forums which have been friendly and helpful. The devs are also fairly active there, so you’ll get good answers. It maintains great integration with iOS and desktop devices (can’t speak for Android), and using it together with a SAML setup is quite a breeze. So far, it has scaled to about 150K small files and 1.5TB of storage. It’s built-in authentication system is also quite robust, with support for TOTP and FIDO 2FA via the plugin system. It also maintains solid integration to Collabora Online and OnlyOffice, allowing real-time document editing with multiple users and guests, which has come in handy quite a few times. Great software overall!

Nachteile: Can be a bit difficult to set up initially. You’ll need a solid understanding of SysAdmin basics to even get off the ground, since it’ll rely on you having a properly configured web server. You’ll also need to know how to properly secure both the installation, as well as the database Nextcloud runs on. A compromise to either of those points would cause a security issue.

Kommentare: I installed Owncloud about 4 years ago, and moved to Nextcloud after the fork. Originally it was kind of a lark-- I had low expectations. Almost immediately I discovered it was a service I use every day, and would never want to do without. Since the fork I've been amazed at the continuing updates which bring better functionality and new features. I'm a committed privacy advocate, and Nextcloud gives me file sharing, contacts, and calendar, in an easy to use interface, all on my own server. Nextcloud Talk, with which I can video conference with my family and business clients, is just icing on the cake. If you haven't tried it, you should, it works amazingly well.

Vorteile: I'm a big privacy advocate, so it is important to me to keep control of my own files, contacts, and calendar, away from the prying eyes of Google and their ilk. The ability to quickly create a password protected folder, and share it with any client or customer, with full read-write capability, is a feature I've come to depend on, on a daily basis.

Nachteile: I miss the ability to link my Google Drive and Dropbox storage but, honestly, I didn't use it that much anyway (privacy issues). Less of a big deal anyway, since I've now been able to upgrade my home internet service, and I can run a second version of Nextcloud on a Raspberry Pi at home, and Federate the connection to my main VPS. That means I can connect as much storage as I need. In the past I've had trouble with some of the updates, but that hasn't been an issue for more than a year. I guess I really have no complaints.

Kommentare: Nextcloud allows us to collaborate with 150+ team members to build our organization's before we release it to our audience.

Vorteile: Multiple accounts / instances synchronization works seamlessly on different desktop OSes. Nextcloud manages document versions quite well and can restore documents that were mistakenly / accidentaly deleted on synced desktops.

Nachteile: It's sometimes hard to know why conflicting versions appear.

Kommentare: The client is good, but it is difficult to uses the history of synced files. Everything is marked as "updated now", and there is no indication if the files have been sent, updated, received, and especially by which user ... In that matter, tools like sharepoint does it better.

Vorteile: It works on raspberry pi (20 Watts only) and therefore it is possible to build a local storage inside my organization with unlimited disk storage and only on intranet (speed up the transfer and uses less bandwith and energy).

Nachteile: The sharing of multiple folders to multiple users is difficult to follow. About 100 filders are quickly shared in the owncloud root folder. One should add a folder synchronization to each of them manually on each client to really share the files (otherwise, it is just an authorization to access the files, that usually never reaches the several clients even if available in the root folder).
A solution to really share (and put the files on the final user hard drive) should be perfect. example : start the sharing of a folder and select which user and where (in which folder of the final user hierarchy) it should start to synchronize : no action on the final user client (mayba an approval ?)
