Backup Applications
• Backup applications: – LAN-free and serverless backup – Remote backup – Snapshots and split mirrors – Synchronous mirroring
• Key benefits of SAN: – Reduced backup and restore times – Remote connectivity – Continuous operation
– Disaster-tolerance solutions
SANs can provide substantially increased performance for backup and recovery:
In a 24x7 operation, there is no good time to take systems down for backup or maintenance.
Continuous operation requires fault-tolerance, rather than recovery. Disaster-tolerance requires complete, current, and accurate copies of data in widely dispersed locations.
