James, it's okay, I eventually found this: About Deleting, Moving, and Renaming Files
When you delete a file from your computer, the file is marked for deletion on the backup servers. The file is permanently deleted from the servers 30 days after it was deselected. When you use the MozyHome Prefererences window to deselect a file to exclude from future backups using the File & Folders Tab, the file is marked for deletion on the backup servers when you perform your next backup. The file is permanently deleted from the servers 30 days after it was deselected. When a file is marked for deletion on the backup servers, MozyHome immediately releases the storage space used by that particular file. The most recent version of the file is kept for 30 days, after which the file is deleted permanently from the backup servers and is no longer retrievable. MozyHome recognizes when you delete, move, or rename files on your system, and updates the backup servers. MozyHome keeps an exact copy of your selections on the Mozy servers, meaning that all changes (deletions, moves, and renaming) of files on your system are mirrored. When you rename a file on your system, MozyHome treats it as a deletion of the old file and the creation of a new file with the same content. If you need to restore the file, and the restore date is prior to the renaming, the file uses the old name. After the date of renaming, the file uses the new name. When you move a file from one location to another on your file system, MozyHome treats this in the same manner as a renaming.
