How to avoid base backup in automated failover

Hi all,

Recently I was writing an application to implement automated failover with
env: Two 2008 R2 servers, Network area storage, asynchronous replication,
WAL archive on primary enabled.

Is there any way to avoid starting standby server always from base backup in
automated failover. I see the database is growing huge. I can't keep doing
base backup every day.

Please suggest solution

Regards,
Reddy
