3. 3© Copyright 2013 EMC Corporation. All rights reserved. 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

4. 4© Copyright 2013 EMC Corporation. All rights reserved. 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

5. 5© Copyright 2013 EMC Corporation. All rights reserved. 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

All rights reserved. “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."
