I have a small doubt.

full backup F1 6 am
t-log backup T1 7 am.
t-log backup T2 8 am.
suppose if the system crashes at 8.30 am

the restore order is F1 T1 T2.
through this we can restore up to 8 am . then what abt 30 min data.
how can we eliminate that data loss.
generally people say we have to use tail log backup.
if we are not able to acess to sql server how can we take tail log backup.

You must be able to backup the transaction log in order to get any data after 8am.

Are you going to give this site credit for all of the questions/answers you are getting?
