Hi All,
i'm trying to configure mirroring on the same server on two different instances without witness. at the end of configuration, i'm getting the error insufficient transaction logs. error nnumber 1478.
i read in a forum that need to take the log backup and restore that too. is it necessary? i've configured around 100 times successfully, never ever i restored with a log backup. but now i'm getting this kind of error.
Note : i'm testing on a new database, which has not even had a single table.

thanks in advance

Maybe your full backup is too old...? That the translog has been truncated after your last full backup? The mirroring agent reads from the transaction logs..not the database itself.

Mirroring requires a full restore and at least one tlog restore. If you've configured mirroring successfully in the past, then you've always done at least one tlog restore as it would not have worked without it.
