BURA – When Backup Recovery and
Archive come together

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,
months)
years, or decades)
•Data typically overwritten on
•Data typically maintained for
periodic basis (i.e. monthly)
analysis
•Not for regulatory compliance –
•Useful for compliance
though some are forced to use
