Strategies for Data Backup and Redundancy

With Dramatic increases in data expansion and an increasing dependence on information for business continuity, companies will need to know that their information is stored safely and can be retrieved quickly – with the minimum of space for the most benefit. Keeping pace with the Data explosion is not straightforward. With as much as 50% increase year on year and increasingly complex IT environments, many backup systems are struggling to cope. At exactly the exact same time, achieving high levels of redundancy can be costly and employers risk paying a premium for high-spec solutions that far outperform their demands. Every customer is Different, both in terms of budget and architecture. So everything has to be considered – from easy off-the-shelf tools to solutions which are custom fit to your systems – using a continuous focus on increasing capacity and reducing costs.

The technology overlap involving backup, redundancy and archiving can often result in confusion, but each has a different role to play in streamlining and protecting data. Backups essentially create another copy of data at particular points in time, ideally maintaining multiple historical copies. Redundancy establishes a direct copy of a whole system, ready to take over if the original system fails. Backup provides a certain degree of redundancy, and redundancy a fundamental level of backup, but neither is standalone solutions.

Archiving makes a Main Recover Your Data of selected data with the purpose of keeping data in the long term. Not all of the data found in a backup will finally wind up in an archive so archiving is rarely a decent backup solution in itself but as a complementary strategy; it can substantially optimize the data storage procedure. Most backup strategies Rely on a combination of backup, archiving and interrogate. An important element to keep in mind when planning a backup schedule is prioritization of information. Not all information is created equal and a tiered backup strategy that restores the most critical software first will get you back in business faster and reduce data storage costs.

Recover Your DataComplete – A full backup Copies each file in a system. Restore times are fast but copies are time-consuming and space-intensive so scheduling and data prioritization are significant considerations. Differential/Incremental – Differential and incremental backups fill in the gaps between full backups, storing any changes to information. They require a portion of the host CPU cycles, bandwidth and storage space. The risk of information loss is obviously greater than full backups and restore times are slower but Blueberry can use specific snapshot technology like Amazon EBS to reconstruct images more rapidly.

Synthetic –¬†A Synthetic backup consolidates a complete backup and subsequent incremental backups into one file. Recovery is fast, using less server cycles and bandwidth.

Continuous Data Security –¬†Compared to scheduled backup, continuous data protection (CDP) continuously tracks data alterations. CDP saves all data and changes can be retrieved rapidly from any location in the past. Bandwidth weight is considerable but using compression methods and block-level incremental backup, Blueberry can considerably reduce this load.
