I have an Office365 subscription with 1TB of OneDrive online storage included. My main usage is "sort of" backing up my digital lossless music library of about 1400 albums. The main issue is, that i find uploading the music via browser is sometimes very slow - despite fast internet connection - and often unstable (failed uploads). Regardless of the used browser. Is there any other more reliable option to upload files to OneDrive? The OSX app doesn't seem to support one-way uploading without syncing, which don't want.
