How DPM protects data

DPM Finds Files That Make Up Data

Back end server 1

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

Back end server 2

D:\ + ContentDB3.mdf + ContentDB3.ldfE:\ + ContentDB4.mdf + ContentDB4.ldf

DPM Identifies Blocks That Compose Files

E:\ + ContentDB1.mdf + ContentDB1.ldf

F:\ + ContentDB2.mdf + ContentDB2.ldf

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

1000 Windows clients

2000 SQL Server databases

25 Terabyte SharePoint farms with over 1M objects

40 Terabytes of Exchange storage groups & databases

* May vary based on size of each datasource, as well as scaling of DPM server memory, disk and I/O architecture
