Big Data best practices: Don't take risks with your backups

One of the problems with http://www.aliyun.com/zixun/aggregation/13584.html "> Mass data  (also known as" Big Data ") for your storage environment is how to effectively protect that data.

PB-level data storage can cause confusion in backup windows, and traditional backup designs cannot be processed for millions of small files. The good news is that not all large data messages need to be backed up in a traditional way.

Nick Kirsch, the product director of EMC's scale-out NAS platform Isilon, says the product is able to process data more intelligently while backing up large data. His advice is that you should carefully identify the data you want to protect before you consider how to protect the data. Device-generated data, such as report files in a database, can be easily retrieved than backup and recovery.

When you try to protect large data stores, you may need a larger two-tier storage system, extra bandwidth, and windows that hold more data backups.

Compare the cost of protecting and regenerating data. In many cases, source-side data should be protected, Kirsch said, but it may be cheaper to rerun program generation for data generated by various programs than to protect the data.

Data protection

For protection against user or application failures, the Ashar Baig,taneja Group of senior analysts and consultants says snapshot technology can be used for large data backups.

Baig also recommends using a local disk system for fast and simple first-tier data protection. "To find a way to make a copy of the data locally so that you can make a quick recovery locally," he said, "make a local copy, and use the mirroring technology to do it quickly, and mirroring-based snapshots and replication technologies can actually take care of performance while improving speed." ”

If you want to customize a new backup system for large data, Baig recommends that you consider using your current backup device and software.

"Any equipment you purchase for large data must be integrated with existing systems," Baig.

Backup software vendor CommVault Senior product and solutions marketing director Jeff Echols says his big data customers are or are planning to use tape systems and cloud vendors to protect offline data. These legacy tape systems are retained for cost and existing infrastructure, but are migrated to archive applications rather than primary backup systems.
