I am trying to backup my filesystem to my SSD so I can boot from SSD. The issue I am having is RSYNC is giving me errors. I am running 
```
sudo rsync -aAXv / --exclude=/media/* --exclude=/mnt/* /mnt/mydrive
``` 
which should carry over permissions and groups. I don't want to mess anything up once I have my ssd ready so I want to preserve all groups and settings. I have a bunch of programs running on here. plex,sonarr,radar. 

The destination folder is mounted as root. I am running rsync as root. What am I missing here?

What file system is on `/mnt/mydrive` is the question? It's FAT32.
