One of the pressing concerns of data center managers today is—data storage optimization. This is especially significant when primary data stores for cloud backup are relatively expensive and take a large chunk out of the IT operational budget. While data de-duplication for cloud backup can reduce the repetition of data in stores, it is real time data compression that reduces the size of the database and saves on data storage space.
Real time data compression is an inline technology often used with cloud backup and recovery technology. This optimization technology kick starts at the NAS head and processes the data as it flows in or flows out of the NAS head. The data is reduced by about 50% and this reduction impacts all cloud backup storage tiers till there is overall increase in storage savings and efficiency.
Inline technologies often raise the specter of performance impact. While it is true that most commercial compression technologies create some kind of performance slow down, enterprise class real time compression cloud backup and recovery algorithms work in real time to eliminate any such performance impact. Real time compression algorithms for cloud backup and recovery do not even create a blip in the radar of data delivery performance.
Interestingly, a few tests show that the performance of the system even improved with real time compression. The reasons cited are:
- Data is consistently and constantly validated before delivery.
- The cache utilization improves and delivers better response times to the end user.
- I/O components have to process only half the volume of data with the same amount of effort.
- Only 50% of the volume has to be delivered.
- There is an increase in overall efficiency which compensates for any latency arising from compression or decompression of data.
Real time compression works with all kinds of data. The data may be a snapshot of data or a writeable clone of the data. It can also work in conjunction with de-duplication making the process of data storage optimization more efficient and effective.
As a result, real-time data compression in cloud backup is often regarded as a seamless method of increasing storage capacity in a NAS environment. It addresses most performance concerns of IT managers and is efficient, effective and economical in the bargain. It creates financial and operational savings on cloud backup storage tiers at all stages of the data life cycle. Migration, replication, mirroring, backup or archiving—all kinds of data handling tasks performed by cloud backup data mangers are automatically and efficiently downsized. The bonus is there is no specialized requirement for client software or hardware changes.
