What is Offsite Backup? Traditional Tape Software Replication Appliance (Hardware) Replication Virtualization Replication for DR

Considerations What problem are you trying to solve? –Need better RTO/RPO? –Eliminate possibility of stolen/lost tapes? Are your servers virtualized? Can you get adequate bandwidth? Do you need a DR site? –Or can you send your data to a cloud? Do you have enough disk space for retention?

Other Considerations How far away is far enough? What are your RPO and RTO requirements? How many times a day do you backup? How long of retention periods are needed?

Traditional Tape Positives Low cost Familiar Process Somewhat Simple Long Retention Supported by most backup software Negatives Prone to Breaking Slow Can be stolen/lost Requires people Tapes go bad Requires a compatible tape drive for future restores

Software Replication Positives Disk to Disk based Fast Backups and Restores Hardware agnostic Can work with Hardware Appliances* No user intervention required to replicate Fairly Cheap Negatives Requires Bandwidth Can be complex Resource Intensive May effect other services like VoIP, Remote workers etc

Software Examples with Replication Veeam* Appasure Replay Quest vRanger* Acronis *Virtual Machines only

Appliance (Hardware) Replication Positives Disk to Disk based Fast Backups and Restores Software Agnostic (in some cases) No user intervention required to replicate Deduplication and Compression Negatives Requires Bandwidth Still Requires Backup Software Can be complex Expensive Can be vendor specific May effect other services like VoIP, Remote workers, etc.

Appliance (Hardware) Examples Exagrid DataDomain HP StoreOnce Dell PowerVault

Virtualization Replication Positives Quick DR Recovery Integrated Snapshot Technology Change Block Tracking Negatives Requires Bandwidth Can be complex Expensive Can be vendor specific May effect other services like VoIP, Remote workers, etc.

Minimizing Bandwidth Needs HyperIP by Netex

Minimizing Bandwidth Needs Helps reduce WAN load by 60%

Tips Without adequate bandwidth replication will never work –Consider a dedicated circuit just for replication if your have a lot of data or a lot of daily change data Even with dedupe and compression you will need a massive amount of disk space! –Retention will require as much storage space as your backing up times the number of weeks you want to retain that data Deduplication and Compress is resource intensive. Get a good backup server or a hardware appliance
