I've been using an HDD for backups since 2021, and it's now holding 2.6 TB of data. I set it up to back up everything, and it has been unattended for several years. Recently, I've noticed that even with 100 GBs reported as free space, it drops down to just 9 MBs almost immediately. I used WizTree to check the usage, but I'm worried about deleting backups since I'm not very tech-savvy and I fear I might remove important system files. I've tried adjusting the settings to limit the backup size, but they seem to revert back to saving everything indefinitely. I read that removing older backups could help, but I'm unsure how to do this safely.

Backing up your hard drive to the same drive doesn’t make much sense—if that drive fails, you'll lose everything, including your backups! It’s better to follow the 3-2-1 backup rule: keep 3 copies of your data, on 2 different storage types, with 1 copy offsite. If you have another drive, switch to that one for backups to be safer.
Yeah, I was puzzled too. Switching to another drive sounds like a smart move!
