Brad’s Sure Guide to SQL Server Maintenance Plans- P33: SQL Server has a reputation as being a simple database application to install, configure, and maintain. This is a little misleading. SQL Server is a powerful relational database that can handle the needs of the largest organizations and, as such, its proper maintenance almost certainly requires the attention of an experienced DBA. | Chapter 12 Back Up Database Full Task also that the full database backup job will be completed before people come to work in the morning.
