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

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 needs1
Minimizing Bandwidth Needs

Helps reduce WAN load by 60%

slide14
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
