Backup Strategy

Backup Strategy

An effective backup strategy is the cornerstone of any company's data protection - but beware, simply copying files is usually not enough. You need an idea that will realistically reduce the risk of losing critical information; this can be the simple and proven 3-2-1 rule, or three copies - two on different local media and one in the cloud. In this category, we describe how full, incremental and differential backups differ and when it's worth reaching for which solution - and honestly, it sometimes depends on the scale and type of application. You'll find practical tips on automation, regular testing of recovery procedures and monitoring the effectiveness of backups; in my experience, many companies skip testing, which later comes back like a boomerang. We also discuss topics such as frequency of backups, retention periods or integrity verification - with specific examples, such as backing up a database every night and system images once a week. We devote attention to strategies for a variety of organizations - from small offices to medium-sized enterprises with extensive infrastructure: servers, databases, virtual environments and business-critical applications. This is practical knowledge that, while seemingly obvious, can save a company from the consequences of a disaster or attack.
