DPM 2007 – protecting Applications
How DPM 2007 protects data
DPM 2007 – Express Full’s
DPM Finds Files that Make Up Data
D:\
+ \SQL_data
+ \Customer.MDF
E:\
+ \SQL_logs
+ \Customer.LDF
DPM Identifies Blocks that Compose Files
• DPM filter creates a volume map, to
monitor which disk blocks contain
portions of the files to be protected
D:\
+ \SQL_data
+ \Customer.MDF
E:\
+ \SQL_logs
+ \Customer.LDF

MSCS Cluster
• Traditional cluster configuration,
two servers – one dataset
• Automatic Failover to new server
name
• Protection continues seamlessly in
failover and failback scenarios, no
user intervention needed
• DPM detects cluster configuration
and associated server names
when protection is setup

Exchange 2007 – LCR
Local Continuous Replication
• One exchange server with
redundant copy of database
• Failover to redundant copy in
case of database corruption or
drive loss
• Backup from Active DB drive

• Redundant exchange servers
and redundant databases
• Can be geo-diverse
• Databases logs are replicated

No more failed recoveries
Near zero data loss for Exchange, SQL, and SharePoint
Seamless Disk-to-Disk-to-Tape for backups
Recoveries within minutes instead of hours
Unified policy allows protection of multiple data types to any
media – in one schedule and with common tuning options
Eliminate the backup window of your production servers
Shrink potential data loss down to 15 minutes
Application recovery direct from backup UI – no pre-staging
Enable end-users to perform their own recoveries
Remove tapes from branch offices and centralize
backups at the datacenter
