Tresorit has a Linux client.

I switched to linux (POP OS) as daily driver recently. Using selfhosted nextcloud and had 0 issues installing client and syncing. Didnt try google and other big guys yet

Has anyone tried cryptpad.fr. I'm considering it, but I have yet to try it.

I use kDrive and it works well with Fedora. Infomaniak, the company behind kDrive, is from my country, Switzerland. It uses a lot of renewable energy and the heat from their servers is used to heat buildings in my city.

Last time I tried, Dropbox has the best linux app. It even supports LAN syncing and integration with nautilus (ubuntu default file manager). However I need to move to onedrive because dropbox is just too expensive

with rclone you can mount cloud storage as a folder

I use my own NAS along with syncthing to backup and sync stuff across my phone, laptop, and desktop. Before that I was using mega.nz with its native Linux client, which worked fine sans a weird issue where it'd repeatedly transfer the same file forever.

Way back I also saw a paid 3rd party Linux-native app that supposedly works with all the major personal cloud carriers, though I never ended up using it and have long since forgotten what it's even called.

I use Google cloud with nautilus, and before that I used google-drive-ocamlfuse on my Chromebook with custom firmware. All this just so I don't have to use their stupid website.

I am currently using InSync on 64-bit devices and Overgrive on 32-bit devices. Overgrive works just fine on 64-bit devices tol but Insync is slightly more userfriendly.

Try nextcloud

If you only need data storage, then seafile is your tool of choice.

kdrive or nextcloud.
