Need someone to look over my cron for rsnapshot

Hello, and thanks David for the rsnapshot advice... I am trying to  
setup cron to mirror my rsnapshot.conf interval (which is:)
interval        hourly  6     'every 4 hours
interval        daily   7       'every day
interval        weekly  4       'every week
interval        monthly 12      'every month


0 */6 * * *       /usr/local/bin/rsnapshot hourly 'will run every 4  
hours every day
15 0 * * *       /usr/local/bin/rsnapshot daily 'will run every day  
at 12:15am
30 1 * * 0      /usr/local/bin/rsnapshot weekly  'run 1:30am every sunday
45 2 1 * *      /usr/local/bin/rsnapshot monthly 'run 2:45 every 1st of  
the month


Are my comments right? and does my cron match my rsnapshot interval?


thanks!
