BURA – When Backup Recovery and Archive come together
Yoel Ben-Ari- MBI
Traditional Backup and Archive Process
• Production environment grows
• Backup environment capacity tied to production
• Growth of Archive environment
Archive Processes
BackupProcess
ProductionApps
For an average customer, that one file gets backed up:1. Weekly for four weeks x 10 on the file server = 40 copies2. Daily for four weeks on the e-mail server = 28 copies3. Monthly for five years x 10 of PST = 600 copies4. Monthly for five years x 10 of file = 600 copies
The Life of a Typical 1 MB File
User creates 1 MB ppt file and e-mails it to 10 peopleThey all save the file on the network driveA month later the e-mail is put in a PST folder on the network drive
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 againMultiple identical copies of informationCannot finish backups in available windowsRecoveries 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
Backup using incremental or differential technologiesInterleave/multiplex multiple servers onto the same tapeDon’t backup as oftenJust don’t backup some data
Recover from full backupsOne server per tapeBackup as often as possible (reduce log impact)Backup everything
Accelerating Backups Accelerating Restores
Backup & Archiving ARE Different
Backup:
•A secondary copy of information
•Used for recovery operations
•Typically short term (weeks or months)
•Data typically overwritten on periodic basis (i.e. monthly)
•Not for regulatory compliance –though some are forced to use
Archive:
•Primary copy of information-
Available for information retrieval
•Typically long-term (months, years, or decades)
•Data typically maintained for analysis
•Useful for compliance

EMC Xtender Family of Archive Software
Data collector captures data from file systems
Interview provides insight into current operations
Captured data and interview are sent to EMC corporate for analysis
Report with customer data and TCO results returned to EMC field
EMC field delivers report
File System Assessments Identify Inactive Files
70% of data has not changed in over 6 months
Disk Xtender Moves Inactive Files to Active Archive
FSA for Windows Servers reduces backup and restore windows, resulting in improved RTO and RPO and lower production storage costs

Files can be moved to single or multiple targets, or across multiple tiers
UNIX, Linux, Windows,NAS filesystems
Policies classify files: Name, Size, Type, Last Access, Last Modified…
View is always local, and access is transparent to user or applications
How Centera Works
Database stores Content Address
for future reference
Centera performs Content Address calculation and sends address
back to application
Application server sends object to Centera over IP network
Object is created and sent to
