How do I find and delete an aborted backup file

Attempt at migrating Apps pool to a NVMe went wrong.

How do I locate the partial backup and delete it.

The process of backing up was discussed in “Migrating Apps from the TrueNAS HDD pool to a NVMe on the server

Ran the following: sudo rsync -avAHX /mnt/.ix-apps/ /mnt/<old_pool_name>/backup/

However the entire PLEX library was copying over to main pool instead of the desired NVMe pool so aborted.

Used space was 29% now its at 50%
