Agenda
   Backup Best Practices
   Mailbox Recovery
   Recovering Stores
   Replacing an Exchange Server
   Alternate Server Recovery
Backup Best Practices
Backup Applications
   Windows Backup
       Integrates with Windows Server and
        Exchange
       Accesses Information Store directly
   Shadow Copy
       Speeds up backup
       New in Windows Server 2003
   Third party backup programs
Backup Best Practices
Implementing Backups
   Design and schedule backups
       Service level agreement
       Tape rotation
   Leave Circular Logging disabled
   Log file location
       Keep log files and databases on separate

Backup Best Practices
Types of Backup
Type        Recovery                       Backup
Full         One backup set                Large
             Fast                          Slow
Differential Last full backup + latest     Smaller
             differential                  Faster
             Slower
Incremental Last full backup + all         Smallest
             subsequent incremental sets   Fastest
