Applying Transaction Logs to an existing Database I am wondering if this possible, I can not seem to apply another transaction log.

I have restored the Full database backup, the differential backup and my last Transaction Log WITH RECOVERY. If later on I need to apply the next Transaction Log in sequence to it, what do I need to do? 

I tried applying the Transaction Log and it states: 


  The log or differential backup cannot be restored because no files are ready to rollforward.


For each time I need to add a new Transaction Log, do I have to go through the steps of restoring the backup database, restoring the differential database and all transaction logs again?
You have to start over and restore full and diffs with no recovery and then the tlogs  with stand by option. This will allow you to restore tlogs later as well.

You can configure logshipping with option of stand by, so you can read from the secondary database.

There will be a .tuf (transaction undo file) file created when you restore tlogs with standby option.

For manually restoring tlogs use restore gene or you can just use logshipping for automated restores.
