Please describe your issue in as much detail as possible:
When trying to back up a game to disk, nothing is stored and the backup size is 0 bytes.
There are no log messages if Steam is run from a terminal. I've tried with disks formatted exfat, ext4, etc. all have sufficient storage space for the game (and either way there is no error message about the disk being full or incorrectly formatted).
Steps for reproducing this issue:
- Attempt to back up an intstalled game to an external drive
I have the same issue when trying to backup to remote cifs mounted folder. Distro Kubuntu 24.04. Backing up to local folder works fine.
It turns out the issue was caused by flatpak's sandboxing, the solution is to install Flatseal, then add rw permissions to the directory that you want to save your backups to

Another solution was to add a link to the destination through flatpak. I saw it on Reddit but it'll take me sometime to find that post. The problem is that you only add a link to the default installation location and not the other directories.
Once added, the backups are possible.
Running Steam natively (no flatpak sandboxing) this issue happens to me as well.
What's interesting though is that backing up a game (preferably small, tried Patrick's Parabox) to a destination like /tmp makes the backup function work afterwards.
