Unable to rebuild discourse due to no space left on device

I get the same No space left on device error when I try to backup my Discourse:

[2022-11-15 08:23:38] EXCEPTION: /var/www/discourse/lib/discourse.rb:131:in `exec': Failed to gzip archive.

gzip: /var/www/discourse/public/backups/default/forum-leasehackr-2022-11-15-080439-v20221110175456.tar.gz: No space left on device

My backup and image uploads are set up on DigitalOcean’s Spaces and have been working fine for a few years until recent months. Here are what I have tried so far:

  1. I cleared all hidden multipart uploads on my DO Space. There should be more than 100GiB of storage available on my DO Space.
  2. I tried rebuilding and cleaning up using the following commands:
cd /var/discourse
apt-get update
apt-get upgrade
apt-get autoclean
apt-get autoremove
./launcher rebuild app
./launcher cleanup

Anyone knows why my backups keep failing still? Thank you!
