symlink

A 14G backup folder filled the root disk. The move-to-block-storage-with-symlink pattern relieves disk pressure without deleting backup data.

TL;DR: When the root disk hit 95 percent, the culprit was a 14GB WordPress plugin backup folder. Instead of deleting it, the fix moved the folder intact to block storage and left a symlink at the old path, dropping usage to 44 percent. Verify file counts, use absolute paths, and persist the mount in fstab to avoid dangling links.
