Full Backup and Log backup timing

Hi
When I set up a schedule to backup my database and Tlogs, will I then have
to ensure that the database backup has finished before my Tlog backup job
starts? Will it create any problems if the database backup job is still
running when the Tlog backup job kicks in. Is it somethnig I should avoid
happening if possible?
Regards
SteenSteen
In my copmpany we do every night a complete backup of the database (let me
say at 01 am) and log backup we begin at 8 am in the morning. First thing i
get an email or even sms whether or not the full backup was complete
successful.
You will have to make sure that your full database was successful before the
log backup will start.

A quick test seem to confirm that, but of course a quick test in this case is not conclusive...

backup while a Full backup is in progress but it can not finish until the
Full is done. There is no problem doing this as far as errors and such.

The database I tested on is only 50 MB in size, I didn't see that wait in there...
