Thanks, and I definitely understand it is not intended at a real backup solution. I am investigating ways to get my local backups off-site as an alternative to paying for raw cloud storage space, which would have similar features to nextCloud in terms of just dumping files to it. This would just be an off-site copy in addition to my several local backups. I looked at GoodSync but I would prefer not to use proprietary software.
I do versioning of important files in my local NAS and other backups, so again not worried about having nextCloud handle it. Hoping to be able to bulk load a copy of all the most important files onto an external drive either with the OS filesystem tools or via a local instance of nextCloud (if necessary) and then transport that to a remote location and connect to a next Cloud instance there to continue future, incremental backups. Only want to essentially mirror what I have locally.
Is that possible with nextCloud? Would I need to transfer the nextCloud db along with the initial seed of files?
Also, does nextCloud store the original files or some form of blocks or chunks?
