Question about Point Time Recovery

Hello All,
I have questions about point in time.
I took database backups and transaction log like the following.
Database backup at 1:00 pm on July 20
Transaction backup at 2:00 pm on July 20
Database backup at 1:00 pm on July 21
Transaction backup at 2:00 pm on July 21
Can I restore the database to 3:00 pm on July 20?
Can I restore the database to only 2:00 pm on July 20?
Would you please explain it?
Are there any good documents or web site about point time recovery?
If point in time restore button is grey, I cannot restore a database to point
in time? Is it right?
Thanks in advance,
Do.

POINT-IN-TIME recovery can be made only if your database is FULL recovery
model. BULK_LOGGED recovery model will not allow
POINT-IN_TIME recovery.
Based on your backups below you could do a seperate point in time recovery
till 2:00 pm on July 20 or 3:00 pm on July 20
(Provided your database recovery is FULL)
-- For 2:00 pm on July 20
RESTORE DATABASE DBNAME
FROM disk='c:\backup\dbfullbackup_20_july.bak'
WITH NORECOVERY
GO
RESTORE LOG DBNAME
FROM disk='c:\backup\Tranbackup_20july_02PM.TRN'
WITH RECOVERY, STOPAT = 'Jul 20, 2005 02:00 PM'
GO
-- For 3:00 pm on July 20
RESTORE DATABASE DBNAME
FROM disk='c:\backup\dbfullbackup_20_july.bak'
WITH NORECOVERY
GO
RESTORE LOG DBNAME
FROM disk='c:\backup\Tranbackup_20july_02PM.TRN'
WITH NORECOVERY
GO
RESTORE LOG DBNAME
FROM disk='c:\backup\Tranbackup_21july_02PM.TRN'
WITH RECOVERY, STOPAT = 'Jul 20, 2005 03:00 PM'
GO
Are there any good documents or web site about point time recovery?
See POINT IN TIME in books online
If point in time restore button is grey, I cannot restore a database to
point in time? Is it right?

Hi Do,
Yes. First restore from the full backup, with the WITH NORECOVERY
option. Next, restore the transaction log backup of July 20 2:00 PM,
again with the WITH NORECOVERY option. Finally, restore from the second
transaction log, this time without WITH NORECOVERY, but with a STOPAT
parameter.

Books Online is a great start.

Either that, or you didn't supply all the needed information yet, or you
have to restore some other backup first before you can restore to the
desired point in time. I recommend that you start using Query Analyzer
and typing the RESTORE DATABASE and RESTORE LOG commands. This gives you
much more control over what will happen.
Best, Hugo

Thanks for your update.
If I use the ''Point in time restore'' option, at the end of the restore, my
database is ALWAYS in ''Loading'' state even if I checked the ''Leave
database operational''. Would you please let me know how to restore a
database to point in time in Enterprise Manager? How can I avoid this from
happening?
Best Regards,
Do.
