I have a Microsoft OneDrive account that I mostly use as an archive, where I will manually copy/upload files (such as photos, and various types of documents) that I don’t want synced in real time to my Linux computer. However I do have some folders that I do want synced, and I have set these up in the Insync file manager with CSS 2 way sync.
I noticed that if I create a new file or folder on OneDrive, that change very soon replicates down to my Linux Mint local copy.
However if I create a new file or folder on the Linux Mint local copy, Insync immediately starts turning off sync on those folders/files and every other file with them, and then starts deleting them. They remain intact on OneDrive. After a while, Insync starts re-creating the folders and files by re-syncing all of them from OneDrive all over again. This can take several hours.
What am I doing wrong?
