Prolonga vida útil de um backup de estado do sistema do Active Directory
Cite o link sobre a Vida útil da Lápide.
Windows Server 2003 and Windows 2000 do not allow the restoring of old backup images into a replicated enterprise. Specifically, the useful life of a backup is the same as the "tombstone lifetime" setting for the enterprise. The default value for the tombstone lifetime entry is 60 days. This value can be set on the Directory Service (NTDS) config object.
