This is a tool to help show differences between a source folder, and its mirrored backup folder. It will show you which directories and files are missing or different between the two folder.
This can be very useful to detect files which may have been *accidentally deleted* from your source folder, so you can replace them from your backup before running another mirror.
Specifies the remote host where your backup directory resides
### --backup-remote-user < username >
Specifies the user to connect as, when connecting to a remote host with *--backup-remote-host*
### --ssh-key < key path >
Specifies the SSH key to use, when connecting to remote hosts.
When omitted, and also connecting to a remote host, the default key for the current user will be used (probably).
### --use-rsync
Force this tool to use rsync for comparison. If not specified, directories and files will just be compared normally. In the future, the non-rsync mode might be removed.
