58 * * * * ubuntu /home/ubuntu/backup/mysqlbackup.sh >/home/ubuntu/backup/log/backup.log
This is incorrect format.
The format is described in the crontab file:
# m h dom mon dow command
ubuntu is not a command. Remove it, so the line reads:
58 * * * * /home/ubuntu/backup/mysqlbackup.sh >/home/ubuntu/backup/log/backup.log
Systemwide crontab, specified in /etc/crontab has the user field:

No, if you want to run it as a specific user, you should add it to that users crontab, e.g. runcrontab -eas the user in question. The editor shows you the correct format, complete with examples.
