Backup Restore question

Hi,
SQL Server 2000 SP3 running on Windows 2000 server
Current Backups:
Daily full backup at 10 PM done by Veritas Netbackup
New Backups that will be setup:
Daily Full backup at 3 AM in the morning
Transaction Log backups every hour.
Now my question is, during a restore from the full backup done at 3 AM how
would the restore from transaction logs be affected by the full backup taking
place at 10 PM?
Thanks in advance.You cannot do a restore to a database that is having a backup done at the
same time - and why would you?

Thanks in advance.|||Also, you will have to the use the previous full backup if you want to
restore the 10 p.m. transaction log backup

at 11PM with just the 3AM full backup and then restoring the transaction logs
in sequence until 11 PM and just IGNORING the 10 PM full backup.
The reason I ask is because many times during the testing to restore from
the 10 PM backups (that is done by the third party software), I get an error
message and I do not trust that full backup. Therefore I want to set up these
new backups through Enterprise Manager( I have done it this way earlier and I
find them very trustworthy)
Thanks.

previous full backup and then all of the logs taken after that point in
time.
