Scalability: An Overlooked Consideration in Centralized Backup and Recovery

Ideally, IT departments in a mid to large size enterprises prefer to deploy a single backup solution to manage data protection on all devices, ranging from a handful to thousands of devices which include servers, workstations, laptops and mobile devices. In having a holistic and integrated backup, it is easier to evaluate storage capacity needed, backup windows available, and optimize the backup with one consolidated view of the entire system. This becomes crucial when IT staff is dealing with hundreds of devices, and sometime under pressure to locate and restore critical business data in a matter of minutes.

However, most on-premise backup solutions, such as Symantec NetBackup, were designed with traditional client-server architecture. One server runs as the central point to manage the backups and restores, often serving as a data hub to facilitate data streams coming in and out of the software. While this design is easier to deploy and maintain, it has two serious flaws: lack of scalability and high failure risk.

Recently I talked with an IT manager at a midsize company, they have Symantec NetBackup in place to backup about 300 computers. After I brought out this issue of constraint and cost, the IT manager acknowledged that they have come to a point where they would have to to deploy a second and separate NetBackup to protect the other computers that could not be included orginally. They are concerned and are starting to look for a better backup solution that can in fact scale up to their requirements with one system. Traditional backup software based on client-server architecture has reached its limit.

In addition, failure risk is very high. In order to have 300 computers managed in one NetBackup, the hardware requirement for the single server is high, lots of memory and CPU power to keep the software performing at the accepted level. The cost is thousands of dollars invested in the server alone to backup these 300 computers. Any failure to this server is catastrophic and costly to replace.

Private cloud backup, the new backup architecture, is the on-premise backup solution for mid and large companies. The cloud is actually comprised of a number of servers designed to share the backup demand. Each server can be much less powerful and less expensive than the single server used in NetBackup. New servers can easily be added to grow the cloud to handle more backup demands. Private cloud backup scales up well for large size enterprises.

The failure risk is at minimum in private cloud. If one server goes down, the backup system is still running, the server can be looped back to the cloud once it is serviced. Cost wise, each server shares the backup load, thus can be much less powerful, the cost to repair and replace one server is much smaller.

RingStor private cloud backup goes one step further for superior scalability. With RingStor's US patented technology, devices can stream their backup data to different servers inside RingStor private cloud in automatic load-balancing fashion. In RingStor private cloud solution, there is NO single point where all computers send backup data to.
