I would add --numeric-ids and --itemize-changes. Up to you if you
need --xattrs or --acls.
Also, I prefer to do backups by filesystem so I would add
- --one-file-system and run one rsync per filesystem. This means you
don't have to exclude things like /proc and /dev and any random thing
that isn't normally connected but sometimes is but it also means you
have to list all the filesystems that you do want to backup.
