Do you want a good quality Nextcloud service with Support? NextFiles is a high quality , hight privacy german based cloud provider, a fast and secure Nextcloud service in a German data center with ISO 27001 certification.
The full functionality of Nextcloud, however, is accessed and managed through its web interface via any modern browser on any platform. If you want to self-host Nextcloud then it can be installed on any Linux computer. It can also be installed in Windows and macOS systems using a Virtual Machine. A popular option is to use a Raspberry Pi as a low-cost Nextcloud server. We do have concerns about whether these machines have the oomph needed for the job, although this may be addressed by the much more capable new Raspberry Pi 4 (especially models with 4GB of RAM).
NextCloud: A Dropbox alternative: Introduced by previous developers of ownCloud, NextCloud remains to be one of the, if not the most popular open source cloud storage software. Being open source, anyone can install NextCloud for free. The only service the user will pay for (and at a very small amount at that) is the private server in which they host it on. Now it’s apparent what some may already be thinking – “Google Drive is free to use as well”. This is true, yet both Dropbox and Google Drive still have data limits or are not entirely “private”. This is the advantage of NextCloud being a self-hosted cloud storage platform.
An additional problem is that only the contents of files are encrypted, not their name or folder structure. If you don’t store data on remote storage services, then it is much better to deploy per-file encryption manually before uploading to Nextcloud and/or use full disk encryption on the server drives (for example using dm-crypt or EncFS). Full disk encryption is fairly easy to implement with self-hosted cloud or self-managed cloud instances. If you have a fully-hosted account then this is out of your control, although it is something your provider may do anyway (so ask).
