Plan for disaster recovery in Project Server 2007
Backing up by using SQL Server tools
SQL Server backup and recovery tools allow for the greatest versatility in recovering your Office Project Server 2007 deployment after a failure. SQL Server tools have the following advantages:
Using the Full Recovery model for SQL Server databases allows for recovery to the point of failure in the event of a database loss.
Office Project Server 2007 and related databases can be synchronized by using transaction log marking. This allows for database consistency during database recovery.
SQL Server tools have the following disadvantage:
SQL Server procedures can be complex and require a good knowledge of SQL Server itself and SQL Server databases. We recommend a trained SQL Server database administrator be responsible for these procedures.
Which should I use?
Which backup method to use depends on the requirements of your organization and the availability of trained resources to manage the process. SQL Server tools offer the most versatile options for recovery, but they are more complex to use. SharePoint Products and Technologies tools are simple to use, but only allow recovery to the last full or differential backup, meaning there will generally be some data loss. SharePoint Products and Technologies tools also require the system to backed up during a period of inactivity to ensure data consistency across databases.
Use SharePoint Products and Technologies tools if:
You have a deployment which is not in use for several hours, usually at night, when backups can be performed.
You can tolerate data loss of up to twenty-four hours (the time since the last daily backup).
Your organization does not have trained SQL Server database administrators or IT personnel who can manage the processes of using SQL Server tools.
