Welcome to the forum @ZacharySmith
Assuming you have 2.3.0.0_stable_2026-04-14 (view “About Duplicati” if unsure)
Incorrect Free Space Warnings is my new theory on an issue. It needs dev input.
Assuming you mean it’s the drive root at /, then that fits my theory of the problem.
For a workaround, you can set option:
--quota-disable (Boolean): Disable backend quota
Disable the quota reported by the backend. The option --quota-size can
still be used to set a manual quota
* default value: false
