What is offsite backup
What is Offsite Backup?

  • Traditional Tape

  • Software Replication

  • Appliance (Hardware) Replication

  • Virtualization Replication for DR


Considerations
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
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
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
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
Software Examples with Replication

  • Veeam*

  • Appasure Replay

  • Quest vRanger*

  • Acronis

    *Virtual Machines only


Appliance hardware replication
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
Appliance (Hardware) Examples

  • Exagrid

  • DataDomain

  • HP StoreOnce

  • Dell PowerVault


Virtualization replication
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
Virtualization Replication Examples

  • Veeam

  • Zerto

  • VMware Site Recovery Manager


Minimizing bandwidth needs

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
