Timeshift reporting wrong drive size

I just reinstalled my laptop and installed timeshift, but timeshift is reporting that there is only 130G available on the dive when there is actually 800G free.

If you are using btrfs - you need to do some maintanance

Sounds like you are using btrfs. If you are on ext4 it may be a bit more complicated. Does the output of df -h show the correct free space?

You need to do a scrub and a balance if you have this issue. This should be done from time to time. You can read about how to do it here:

Or, if you want to use a GUI, you can use the BTRFS-Assistant. This is how I do it.
