O problema se deve à grande janela de backup que excedeu a do Data Domain OST_ABANDON_TIMEOUT Configuração.

Entre em contato com o suporte do Data Domain para saber mais sobre o ajuste do OST_ABANDON_TIMEOUT Configuração. A alteração desse parâmetro exige uma reinicialização do file system no acesso ao Data Domain e modo SE.
