Here's a first problem.
There's one system-wide crontab, as well as per-user crontabs. They
slightly differ in their syntax. Per-user crontabs have an implicit
owner, which must explicitely be set in the system-wide crontab. The
syntax shown above contains a username (and thus is in system-wide
syntax), but the system-wide crontab is never ever be changed by
`crontab -e'. So essentially, the command executed here is not
"/usr/bin/backup.sh", but "root /usr/bin/backup.sh". And you probably
should get emails with "command not found" or something like that,
assuming that there's no "root" command on your machine.

This is a correctly formatted system-wide crontab.

Obvious problem: an assumed per-user crontab is wrongly processed
because it is in system-wide crontab format. Just throw out the word
"root" in your per-user crontab file (to be modified by `crontab -e'),
and your script will be executed.
