What to do with full backup and log backup taken at same time.

Hi all,

I have a basic question on restoring backups. Please help me.

If I take 

- full backup everyday at 9am and 

- log backup for every hour

So everyday full backup will be taken at 9am. But there should also be a log backup (which is taken hourly) which is taken at 9am right?

say suppose my database got crashed at 10:10am. 

which log backup should I restore after restoring the full backup(which is taken at 9am)? the 9am log backup or 10 am log backup or both.

Thanks for your time, Srikar
