What I back up is a mix of binary and text files. I understand that

up.
'rsync --dry-run' will tell you if it thinks some files need to be
copied because they have changed. If you do this after your backup
procedure, then you'll be checking that it worked correctly.
Note that by default rsync does not check the content of files when deciding what needs to be updated. It just checks the file modification times and sizes. You have to use the "-c" (--checksum) option to make it check the content.
