Protecting SharePoint DataDPM agent installation

Install the agent on the following servers:Any Web front end server (that is used to invoke the writer)All back end SQL serversAny Web front end servers or application servers (Index) that require file level protection

Protecting SharePoint DataKey takeaways

Entire farm protection with a single checkboxWSS Writer is used to determine all the components to back upExpress full backups onlyDPM works across multiple servers in the farmOn backup completion, DPM queries the SharePoint object model

How DPM 2007 Protects DataDPM finds files that make up data

SQL Server 1E:\ + ContentDB1.mdf + ContentDB1.ldfF:\ + ContentDB2.mdf + ContentDB2.ldfG:\ + ConfigDB.mdf + ConfigDB.ldf

SQL Server 2D:\ + ContentDB3.mdf + ContentDB3.ldfE:\ + ContentDB4.mdf + ContentDB4.ldf

How DPM 2007 Protects DataDPM identifies blocks that compose files

DPM filter creates a volume map to monitor which disk blocks contain portions of the files to be protected

E:\ + ContentDB1.mdf + ContentDB1.ldf

F:\ + ContentDB2.mdf + ContentDB2.ldf

DPM Filter – Volume Map

Recovering SharePoint DataKey Takeaways

Recovery farm required for item level recoveryContent database is restored to recovery farmContent migration packages used (PRIME API)CMP files are left on the recovery farmPRIME API caveats apply

Restoration of the configuration database and Central Administration database is only supported as part of a full farm recovery

Top Reasons For Using DPM 2007A SharePoint perspective

Item level recoveryConfiguration database recoveryProtection for search (DPM 2007 SP1)Protection for customisations and configurationsLess storage required for backups...
