Here are some Q&A's that talk to the alternative:
How to delete directories based on find
output?
How to remove folders with a certain name
find + delete files that contain “.”
And between them I believe my best option for the immediate problem is to remove them from the original drive by executing this in the directory that contains the full backups of the other systems:
cd /mnt/full
sudo rm -rf `sudo find -type d -name '.Trash-1000'`
Search and destroy, hoo-rah! Yes it will take a long time but
It worked and will make for fasterfuture rsync backupswork faster in the future.
This does not solve the rsync bug, though.
If anybody has an answer that will make rsync delete directories that I later add to the --exclude
list, then that would be the answer I will gladly accept.
