What is Replication?

Simply put, replication is the exact cloning of data onto another device, either onsite or offsite (preferably offsite).  Replication gives a business the opportunity to retrieve and utilize data in case of equipment failure or a catastrophic event. Offsite replication is essential to a successful business continuation plan.

Buffalo's Technology Replication feature provides easy and high performance data replication from one Buffalo NAS(TeraStation Series) device to another Buffalo NAS device over the network or the Internet. With replication, rest assured that your important documents are always and immediately backed up onto another device on the network.

NAS-2-NAS Replication

Regardless of RAID and hot-spare, if the entire NAS device were to fail, or if data was to be corrupted on
the NAS device, loss of data would be evident.

To prevent ultimate data loss, an additional NAS device can be connected to the network and daily or
weekly backups of the primary NAS device's data can be copied onto the backup NAS device. In the
event of the NAS failure, data would be accessible up to the last backup on the spare NAS device.
Additionally, IT staff could quickly reconfigure the spare NAS to act like the primary NAS causing minimal
impact to user productivity.

Onsite Replication


Buffalo TeraStation NAS devices support comprehensive backup configurations

Multiple Location Replication

Replication

  1. Who Needs Replication? Anyone who cannot afford to lose data in the event of a device failure. Replicating data onto another device protects that data in the event of a hard drive or complete hardware failure, theft, or fire of a NAS device.
  2. Can I Replicate Data over the Internet? Yes. Buffalo NAS devices that support replication can replicate to other supported NAS devices over the Internet. This allows businesses to have replication between offices in different locations. Having data in different physical locations is one of the best ways to protect a business from permanent data loss.
  3. Can I Replicate in Both Directions? Yes, replication can be configured to operate in both directions allowing for changes on either NAS device to be replicated to the other NAS device. When configured, two shares on two NAS devices will be completely synchronized regardless of which NAS receives new files, changes files, or deletes files.
  4. Can I Replicate to Multiple Devices? Yes, Buffalo NAS devices that support replication can replicate to multiple supported NAS devices simultaneously. This allows businesses to replicate information between a headquarters and multiple branch locations. Alternatively, multiple NAS devices can replicate to a single supported NAS device. This allows for all information from branch locations to be replicated onto a single NAS device at headquarters.

 

  • NOTE: Replicating data over the Internet may use excessive Internet bandwidth depending on the replication configuration. Performance of replication over the Internet will be limited to the speed of the Internet connections.
