In present digital world we can witness massive data growth and fact that the data is becoming the most valuable asset in the industry. Therefore implementing efficient data security solutions has become crucial.

We nowadays expect storage solutions to process application queries without delay and avoiding bottlenecks. This is the most important in primary storage. Therefore all-flash and NVMe storage solutions are increasingly being used. This is fully justified, because usually applications use small volumes of data at the same time.

The situation is different in backup solutions.There we expect efficient and low latency streaming of a backup, but after backup data isstored, we rarely access it. But when backup is finally needed we expect maximum performance from the backup system to restore the critical applications. This aspect is highly underestimated because backup is often treated as a necessary evil. Fortunately an increasing number of customers appreciate efficient backup solutions and their rapid restore capability. This is due to the fact of more and more awareness of data value.

So how to make these two apparently opposite parameters work together?

• instant access without delays for backup and restore
• spacious data volumes with high retention.

Cached Secondary Storage for backup is a solution that supports access to the backup appliance in a similar way to primary storage.  It can be based on efficient HDD spinning disks or SSD media.  When the application sequentially or randomly records data backup appliance analyzes and archives data in the background on spacious data volumes, compressing and deduplication them with efficiency up to 400 times. The effect of this approach is the lack of bottleneck with parallel application backup access in the backup window. It should be noted that a positive side effect of this approach is the fact that the cache area keeps the hottest backup – which enables rapid data recovery in the event of a disaster.

With cached secondary storage for backup we are able to maintain efficiency af the primary storage level combined with capacity of the archive level – therefore for a reasonable price.
