I have some important files that I would like to backup to the cloud. These files include work related things (such as resume and job contracts) and the password safe for Keepass. Sometimes I need these on different devices, for example I need the password safe to be able to log into a website on my laptop. I have been using the Dropbox app and saving all these files to a folder it syncs.
I have two problems with Dropbox 1) it randomly starts even though I set it not to. It's really important for me to control when the app starts and syncs 2) The latest version seems to cause instability issues with my Windows 10 computer. Also I've grown a bit skeptical what large companies such as Microsoft do with personal data so I don't really want to use something like One Drive (Dropbox was nice as it was the only product they had which clearly limits the scope of my data they have).
I don't care if it's not SUPER secure, as I manually encrypt really important things before syncing them anyway. What alternatives are there to Dropbox? I have red Alternatives to Google Drive with emphasis on privacy and user experience? but many of the answers are outdated as the company no longer exists!
