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

File System Data DatabasesMail and Messaging

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
