EMC AVAMAR FOR NAS ENVIRONMENTS

Backup, recovery, and disaster recovery for network-attached storage


Source: “Addressing NAS Backup and Recovery Challenges,” Enterprise Strategy Group White Paper, February 2012

Unstructured Data and File Growth


NAS Backup Challenges

Traditional NDMP weekly fulls (level-0) and daily incrementals (level 1):

Move lots of redundant data– Impacts network bandwidth– Consumes lots of storage

Fulls overrun backup window – Hurts productivity and application

availability

Tedious, multi-step recovery

Expensive NDMP software licenses

High redundancy in file shares


Traditional Network-Based Backup with Proxy Server

• Proxy backup server runs backup agent and resides on network

• NAS volumes mounted through CIFS or NFS for backup to proxy server

Less efficient due to excessive use of network to move data between systems

Can cause performance degradation for backup operations


Traditional NAS-Based Data Replication with Snapshots

• Provides local or remote block-level point-in-time copies

• Frequent snapshots can improve recovery point objectives (RPOs)

Number of snapshots (retention issues)

Storing snaps and primary data on same array risks data loss

Additional license fees may be required

Likely limited to homogenous storage

May pre-allocate disk (~20 percent of total volume) on expensive primary storage


Deduplication Is the Key

Relieves congested networks

Contains backup storage growth

Reduces backup time

Provides more effective disaster recovery

Enables daily full backups

Deduplication is the EnablerMove and store less data

1. Divides data into variable-length sub-file segments

2. Determines if segments are unique or duplicate

3. Backs up only unique data

4. Sends data compressed and encrypted

“EMC Avamar’s NDMP Accelerator solution provides a combination of data deduplication and backup acceleration for even greater NAS backup performance, efficiency and reliability”

“EMC Avamar for NAS—Accelerating NDMP Backup Performance” John Webster, Evaluator Group, June 2011

Avamar and NAS Backup


“With Avamar, we get daily full backups in less than an hour across our existing network links...restore quality and speed also improved.”Bill Meek, senior VP and information systems manager, Broadway Bank

Customer Voices

“With Avamar's NDMP accelerator node, we cut our time to back up 1.2 TB of our NAS file shares from 10-12 hours to about 25 minutes. NAS backups used to take so long - we had to choose which files to back up each night. We now get daily full backups of all of our file systems, which total two terabytes, in under an hour." Michael Phillips, Systems Administrator, Pechanga Resort and Casino
