I'm using NBU5.1 and backing a MSSQL database.
DB full backup is performed successfully once in a day.
But when back up the transaction log, status 1 error is occured always.
Transaction log is backed up per a hour.
Master database's transaction log is not performed.
Is this status right?

Automatic backup is status 1 all the time.
Default-Application-backup is status 0 all the time.

When back up the MSSQL transaction log , is this right?

Please give me a hand.
