The last few years has seen companies take disaster recovery planning seriously, but many are failing to adequately undertake regular tests, to ensure that it is fit for purpose. Without adequate regular testing any failings or shortcomings of the plan will only become apparent when a system failure or disaster occurs, at which point it is too late, which may even impact the chances of a successful data recovery.
Backup systems, whether to tape data cartridges, snapshots or data copied to cloud service providers, must all undergo regular tests and checks to ensure data is being correctly stored and can be recovered when required. Once set in place it is easy to become complacent, which may put your data at serious risk. Loss of data could have serious consequences for the future of your company, with many companies going out of business as a result.
Any changes to your IT infrastructure, from operating system upgrades, new computers and servers, applications and any other hardware such as a firewall may have a significant impact on the correct operation of your backup procedures. Any reliance on individual users to ensure that any critical new data files created are stored in the correct places, so they are backed up, should also be reviewed regularly.
