Sou desenvolvedor de uma pequena loja que não possui um DBA e estou tentando obter o envio de logs com o sql server 2012 funcionando. Estou tentando descarregar os relatórios do sistema de transações para um novo data warehouse e utilizarei esse banco de dados como uma área de preparação.
Executei o assistente de envio de logs e os trabalhos principais de backup e cópia de arquivos funcionam sempre. O trabalho de restauração secundária parece falhar aleatoriamente.
O servidor principal possui apenas um trabalho de log de transações. O backup diferencial está desativado (não tenho certeza se isso importa), mas existe um backup completo.
O servidor secundário é uma instalação nova, sem planos de manutenção, backups ou usuários ativos.
Existe uma maneira de forçar o backup de volta à sincronização ou sempre garantir que ele permaneça sincronizado?
Parece tão frágil. Por favor informar.

UPDATE: executando abaixo da consulta, há algum backup de log de transações ímpares (talvez)
O NUL é o que está na tabela. Não faço ideia por que não é NULL

But what I did find was that BACKUP performed a log backup immediately after the snapshot database backup. And the log backup was taken to the file name “nul”.
