If i have set up transactional log shipping b/w 2 servers and if performs the manual backup of ldf or trn, the LSN get broken and jobs in secondary servers starts erroring.ie transactional log shipping is broken b/w principle and secondary.
but in case of mirroring:
I have setup mirroring b/w 2 servers,and if i performs manual backup then mirroring doesnt get broken.
I know in case 1 we are just transferring the log shipping,that's why LS getting broken in case 2. it is just a mirrored copy.
but want know if there is any backup or restore operation is performed on principle server,what will be internal performs on the secondary servers?Will there be any intimation to secondary server?
