Apparently backblaze does not support renaming files, but copying them in linux does work to rename the files. Is there anyway to support cp paste (transparently in owncloud) to rename as a substitute, instead of directly renaming the file or directory?
b2 doesn’t have a service side rename or copy (yet, I think it is in development) so you have to download files and re-upload them.
Is this using owncloud as a frontend to b2? Not sure I can help with that.
