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