I'm trying to get my head around Linux filesystems and how they relate to the directory structure. I have a filesystem mounted at '/dev/mapper/rhel-home' that's set to '/home', and it's showing 100% usage with no free space available. I also run a backup job that uploads ZIP files to '/home/backupuser/Backups', but it's been failing recently. Everyone seems to think the lack of space is the culprit, but I'd love some confirmation or additional insights. Could this lack of space really be causing the backup failures?

Haha, no tricks here—you're definitely out of space! You should consider doing some cleanup right away.
Just a heads up—a full filesystem definitely affects backups! Usually when VMs are set up, they give certain storage sizes, so that could be tied to your problem. If your VM admin set a low space limit, that could explain the issues.
I totally get the confusion! Learning Linux file structure can be tricky. The way you phrased it makes it sound like you might have a directory under /home rather than a separate mounted disk. Make sure to clarify that detail so others can help you better. If you're struggling with file management, knowing how mounted drives work can really help you troubleshoot issues like this.
Yep, you're spot on! Since the backupuser/Backups directory is a subdirectory of /home, if /home is totally full, any subdirectories are impacted too. I recommend checking which folders are using the most space with a tool like ncdu, and delete any unnecessary files to free up some room.
