I keep seeing this question pop up. "Why doesn't [closed/proprietary technology] work well in Linux?"

This question should be asked at whoever makes said technology. You are their client, why don't they support your operating system?

That responsibility should not fall on the shoulders of the thankless volunteers that do their best to create an awesome OS.

Alternatively you can buy one of the commercial distributions and become a client. Then you can ask your supplier why don't they support that technology.

If you want cloud storage I'd recommend Nextcloud as a service (I'm not affiliated with them, just a customer)

Works like a charm. You can even install plugins. Also, there are other companies that provide hosting so there is no vendor-lock-in.

Google drive integrates simply into the file manager on Gnome for cloud storage. It doesn't do offline file-sync between devices, however.

The Microsoft and Apple products don't support Linux because... Microsoft and Apple.

You can use rclone

Rclone is awesome. Mega and PCloud got native clients that works great. Nextcloud is an alternative.

Nextcloud works great! Includes integrations with GNOME and KDE including taskbar icons etc. and you can pay a service to host Nextcloud for you if you'd prefer that to selfhosting.

I have a self-hosted Nextcloud and my Nextcloud account connected via GNOME as an Online Account. It integrates seamlessly with Calendar, gives me a webdav mount for my files etc. I don't have any issues. I have not added any Google accounts, and definitely no Microsoft accounts. I don't use public clouds for private stuff.

Syncthing is pretty good. I've got a raspberry pi running it on my local network with an old usb hard drive I had kicking around and it works great

rclone for cloud backup

MEGA is an optiom, rclone is the option. Supports next to anything.

rsync/ rclone just works! Have not tried rsync with cloud yet, I use rclone for encrypted backups. Most cloud services are supported including google drive.

Use pCloud.

For command line sync to the cloud you can use rclone. It's FOSS and works with many different cloud providers.

For a constant sync experience you can use insync. It's closed source and requires a license though, but works reasonably well.

Sorry for the lack of direct links since I'm on the phone.

Most people I know who use Linux wouldn't trust Cloud services cause that's just storing your stuff on somebody else machine. You can self hosted service like Next cloud on a raspberry pi or just get comfortable with networking enough to setup VPN and ssh into your home computer from the net to get your stuff.

Mega and syncthing work perfectly fine for me

Mega (Mega Upload) ain't bad, 30gb free. Worth a look!

I used them all, so I get plenty of cloud storage for free

rsync is your friend

I also say that pCloud is possibly the best option. Simple install, free storage, and a cheap lifetime purchase for more storage. My only complaint is that they don't support aarch64 yet, but I don't need think there's really anyone that does yet so I'm living with offline backups.

Don't. Use Nextcloud.

Syncthing has never failed me.

I don't understand those questions. Google Drive is webdav to the best of my knowledge. Anyway, it works out of the with Gnome/Ubuntu. When you connect a Google account, a drive icon appears. Doesn't get more "native".

I get the problem that most vendors don't have an app for Linux, so some functionality is lacking compared to what you may be used to. And cross-platform anything can be a problem, i.e if you really need Linux Desktop + Android + Windows + Apple stuff. (I do and learned to use web-based applications for work.)

What do you really expect from a "Personal Cloud Storage"? not a clearly defined term.

Seafile (needs a paid server as the backend) works nice for syncing files. Google Drives works as network drive. There are tons of backup solutions that work with tons of storage backends (aka professional cloud storage).

the file manager integration with gnome and google drive worked well for me.

My recommendation is to not use them, for privacy reasons.

Chiming in, is there a solid OneDrive client for linux that just works? No collaboration stuff needed for it or other fluff, just simple file sync. I pay for OneDrive family and would be nice to be able to sync files with other ecosystems (Synology, Windows, Android).

I have a Backblaze B2 account I use for other things, I recently created a new bucket on it and attached it as a drive using s3fs. Works fine as far as I can tell (I've not used it much - prefer to keep things locally and just back them up off-site, which is actually what I have my B2 account for), so you certainly can do this with an S3 (AWS) compatible service.

Because Linux is not a platform moneymaking capitalists choose to develop their apps for?

You have Nextcloud for all distros, Flatpak, Appimage. You have Syncthing which doesnt exist on iOS.

I use Google Drive with InSync. It's not free, but it's a good piece of software I've been using for years and it does everything I need.

Someone has a recommendation about how to handle these services?

You don't. Apple is notorious for their walled garden approach. Microsoft has no interest in supporting Linux (why should they?). Don't know about Google.

I am pretty happy with pcloud. They offer lifetime licenses that are really worth it if you intend to stick with them long term. The automatic Backup works great and AFAIK they have clients for all major platform's. The android client could be better, but Windows and Linux works great. Don't miss any functionality and the connection (at least here in Germany) is fast.

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

Because it's a disproportionate amount of effort to natively support an extra OS (particularly one as fragmented as Linux), especially one with such a small userbase that largely isn't interested in using proprietary cloud services in the first place because of data privacy and security concerns.

Obviously not all Linux users are super worried about that stuff (I mean, I use Linux and have a google pixel), but on average the Linux userbase is way way more aware of that stuff than most users who just want their photos backed up without having to worry about it.
