@girish said in Backup size:
Thanks, I deleted files in the Nextcloud recycle bin. Now, after a reboot, Cloudron System Info shows 4.3 GB for the Nextcloud instance. (I had to delete the nginx config of a stopped app to get the system to reboot.)
Thanks, I'll keep both folders. I have no particular goal to remove Discourse or its backups.
I measured /var/backups size by adding up the three separate folders that FileZilla showed me, but I now understand that some files are hardlinks. And the Backup data shows only 4.87 GB now, so my disk is small enough for me to move on. Thank you!
