             Traditional Backup and Archive Process

                  • Production environment
   Apps             grows

                  • Backup environment capacity
 Process            tied to production

              The Life of a Typical 1 MB File

User creates 1 MB ppt file and e-mails it to 10 people
        They all save the file on the network drive
        A month later the e-mail is put in a PST folder on the network drive

For an average customer, that one file gets backed up:
  1.   Weekly for four weeks x 10 on the file server = 40 copies
  2.   Daily for four weeks on the e-mail server = 28 copies
  3.   Monthly for five years x 10 of PST = 600 copies
  4.   Monthly for five years x 10 of file = 600 copies

That 1 MB file takes up over 1.2 GB
         of tape capacity
         This Design Leaves IT Struggling

The same data is backed up over and over again
Multiple identical copies of information
Cannot finish backups in available windows
Recoveries are slow and unpredictable

                 Typical Answers?
        • Add more tape, add faster tape
  • Speed backup and expense of recovery
   (Incrementals, multiplexing, or less frequent backups)
      Backup and Restore – Competing Requirements

Accelerating Backups            Accelerating Restores
Backup using incremental or     Recover from full backups
differential technologies       One server per tape
Interleave/multiplex multiple   Backup as often as possible
servers onto the same tape      (reduce log impact)
Don’t backup as often           Backup everything
Just don’t backup some data
             Backup & Archiving ARE Different

Backup:                            Archive:

•A secondary copy of information
                                   •Primary copy of information-
•Used for recovery operations
                                   Available for information retrieval
•Typically short term (weeks or
                                   •Typically long-term (months,
                                   years, or decades)
•Data typically overwritten on
                                   •Data typically maintained for
periodic basis (i.e. monthly)
•Not for regulatory compliance –
                                   •Useful for compliance
