In IT systems, disaster can strike any moment and in any form. A hard disk failure, third party attack or even human errors can lead to data loss. To recover valuable data in such scenarios, backup management plays an inevitable role. But many times people just configure the backup once and leave it there. They assume that everything would just work fine when things go wrong.

Installing a backup software alone will not guarantee automatic recovery in case of data loss. Integrity check of the backups is also a very crucial aspect in backup management. This means verifying the backup for adequacy, completeness, accuracy and consistency. If the backup is not retrievable at the time of a disaster, that backup solution is of no use. (more…)

A single disk failure instance has turned out to be detrimental to your business. Data loss due to disk failures, human errors or virus attack can lead to business downtime and financial loss.

In spite of that, many business owners tend to overlook this risk and skip the backup process, leading to catastrophic events. For every business that depends on data availability, it is therefore very critical to safeguard and backup data. (more…)
