Addressing use cases of backup systems for remote or branch offices

The next step after you have analyzed your backup requirements is to start identifying the components that together will design your backup system. While designing a complete and efficient backup system you will also need to identify the core pain points that dictate the choices you make in selecting each component. For example, you are required to backup growing number of clients with large data sets, in this case your pain point would be to ensure that the backup solution you consider can account for expandable storage options

Some of the common pain points that you may come across have been listed below:

  • Managing a tape based backup system can pose the following challenges:

    • A backup server and small tape library

    • Shipping tapes off-site for disaster recovery

    • Integration challenges

    • Managed by non-IT staff or less skilled backup staff under guidance from central site

  • Managing a disk based backup system can pose the following challenges:

    • A backup server and deduplication-disk storage

    • Replication to central site

    • Integration challenges

    • Managed by non-IT staff or less skilled backup staff under guidance from central site

  • Managing backups over WAN can pose the following challenges:

    • Source deduplication and backups over WAN can be time consuming.

    • Link unavailability equals to increased risk, thus bringing down the RPO (Recovery Point Objective)

    • Slow rehydrated restores leading to a poor RTO (Recovery Time Objective)

Considering the above pain points of remote or branch office, Veritas NetBackup Appliance provide a solution that includes the following key factors:

  • Provides an ideal backup-in-a-box for remote office/branch office

  • Includes a built-in deduplication and local restores

  • Replicates only unique data to central site via optimized duplication

  • Manage as an independent domain (managed by AIR) or as remote media server (managed by SLPs)

  • Complete protection (physical and virtual) powered by V-Ray Cloud Gateway

  • Fast, policy based Global Disaster Recovery using AIR (Automatic Image Replication)
