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

  3. 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?

  4. 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?

  5. 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

  6. 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

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

  8. 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.

  9. Appliance (Hardware) Examples • Exagrid • DataDomain • HP StoreOnce • Dell PowerVault

  10. 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.

  11. Virtualization Replication Examples • Veeam • Zerto • VMware Site Recovery Manager

  12. Minimizing Bandwidth Needs HyperIP by Netex

  13. Minimizing Bandwidth Needs Helps reduce WAN load by 60%

  14. 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
