Mitigating the Risks of Disk-to-Disk Backup Using Multi-Directional Replication

There are a ton of new
features in the 8.0 release of Asigra Televaulting 8.0 – so many so that here
at DCIG, we are trying to digest all of the new features in bite-size portions.
The one I want to focus on in this entry is Televaulting’s new replication
functionality. Replication is a key function in any facet of the storage
landscape and, with Asigra adding this feature into its latest release of
Televaulting, it becomes an even more robust player in the enterprise space.


Let’s assume a customer or
service provider decides to deploy a full disk-to-disk backup solution for
their enterprise. In these situations, it becomes important that the backup and
restoration process is fast and error free. However with all data now stored to
disk, it’s imperative that if one location becomes disabled for some reason, an
alternate location(s) can simply and quickly take over the backup and recovery reigns.


Most enterprise shops that
have or will have this solution deployed will need to service multiple
locations in order to meet the backup and recovery SLA’s that they have agreed
upon with their customer base. In a typical scenario customers will deploy the
backup and recovery processes as close as they can to the end users to ensure
the most effective use of the local and remote bandwidth capabilities. Secondary
and tertiary sites are then generally configured based upon their geographic
proximity and/or the availability of network connections to the primary site.


While Televaulting has
delivered global deduplication for awhile, enterprise companies need more than
just data reduction and capacity savings, they need assurances of data
availability and resiliency. Using Televaulting 8.0’s new Multi-Directional
replication feature, either location can hum along as a source or target location
while, in the background and transparent to the customer and/or end-user, all
the backup & recovery data across the various locations stays in-sync.


replication ensures that when there is a failure of one or more locations for
whatever reason your clients can continue to restore and backup their data while
you can continue to meet your agreed upon SLAs. Then, once the failed location
returns to service, Televaulting automatically transitions management control and
any new data back to the original location in such a manner that is transparent
to the customers and/or end users that you support.


The addition of Multi-Directional
replication into Televaulting 8.0 should contribute to making Asigra’s
disk-to-disk backup and keeping all backup data on disk a more palatable option
to enterprise customers. Enterprise customers are looking for ways to break
free from the chains of traditional backup and recovery environment but they
also recognize that they need a product that meets their high standards of
availability, recoverability and resiliency. The inclusion of Multi-Directional
replication as a core feature in Asigra Televaulting should help to take
enterprises closer towards their ideal of keeping all data readily accessible
and easily manageable.
