Disk vs. Tape  Disk  No single point of failure architecture  No human errors in loading / unloading tapes  Does not stretch  RAID  Always online  Asynchronous Replication to a remote site  Fast restores and easy to verify backups are correct  Tape  Can be a single point of failure  Human errors in loading / unloading tapes  Tapes stretch and shoeshine  Not online, slowing restores  Not automatically sent to a remote site

LAN-based vs. SAN-based Backups LAN SAN Clients Backup Server Storage System Application Servers Backup Array-based Snapshot LAN-based Snapshot Backup Software Backup Agent  1. LAN-based (no array-based snapshot)  Data takes the full round trip, bogging down application servers, the LAN, and the SAN  2. SAN-based (with array-based snapshot)  Data is copied within the disk array or across the SAN, with no impact to LAN or application servers

Asynchronous Replication for Disaster Recovery Remote Storage System LAN SAN Clients Backup Server Application Server Application Server Application Server Local Storage System  Protection Against Site-wide Failure  Frequent snapshots are transmitted to target side  Snapshots may be mounted on target side  Backups may be performed at the target side  Good way to protect remote/branch offices  Failover / Failback to remote storage system  Pause / Resume, checkpoint restart, deduplication LAN SAN Clients Backup Server Application Server Application Server Application Server Local Storage System Asynchronous Replication Asynchronous Replication

De-duplicate as close to the source as possible LAN SAN Clients De-duplicating Appliance Backup Server Application Server Application Server Local Storage System  Why not de-duplicate right before the backup disk?  Inline de-duplicating appliances either slow backups or are costly  Application servers and networks become bogged down transmitting information that likely will not make it onto the backup disks  De-duplicating appliances fragment data, which hinders restore rates  To test the validity of a backup, a full rehydration of data from the deduplication appliance to a free storage pool is necessary, hindering restore time objectives  Backups cannot be quickly tested to ensure they are correct with de-duplicating appliances
