Data You Don’t Backup is Data You Don’t Want
It’s a simple maxim but it is 100% true. Failing to explore and address all of the ways to which this rule applies to your organisation is failing to plan. And, as that other key business rule goes, failing to plan is planning to fail. Don’t wait until the universe conspires to teach your business a painful and, potentially, fatal lesson about IT support in Sydney.
Backups are the DR Foundation
A recent survey by Zetta found more than a quarter of IT downtime was caused by data corruption and 54% of respondents considered reliability the single most important factor in a disaster recovery (DR) solution. Clearly, robust systems availability and integrity is vitally important.
However, a DR strategy that results in zero downtime has minimal value if it fails to prevent the loss of critical data. There is little point in having robust systems if the data they need has been lost. Furthermore, the frequency with which backups are required has accelerated in recent years.
These Aren’t Your Grandfather’s Backups
Business moves incredibly fast in the era of digital economy, so the old nightly backups approach is woefully inadequate. In a 2014 Acronis Disaster Recovery Survey, almost 80% of companies estimated the hourly cost of downtime at 20,000 dollars or more. This means there is a huge financial incentive to ensure your IT support in Sydney includes effective DR strategy.
Basic Backup Options
The basic elements of effective backup regimes are quite simple and straightforward:
- Onsite – Available on networked resources or physical media like hard disks, onsite backups provide quick availability and minimal downtime. They cannot, however, be made 100% secure against disaster at the site.
- Virtual Offsite – Typically backups in the cloud, these provide security against loss of or damage to backups kept onsite. However, they are vulnerable to network/cloud downtime or corruption and even, potentially, disaster at the site providing the cloud service. Their availability is also limited by bandwidth.
- Physical Offsite – The most secure, and vitally important, form of data backup is the physical offsite backup. Complete sets of critical data are stored on physical media such as hard disk or tape and kept in a location far from the site. They are kept secure from theft, tampering, and disaster. Their biggest limitations are to the frequency of backup and the speed at which such backups can be accessed and used to restore data.
In addition to establishing reliable backup formats, effective backup cycles or rotation schemes are required. Which data to backup, when to back it up, and when to rotate backups so that, in the event of the loss or corruption of data or systems, data from the right point in history can quickly be used for disaster recovery in Sydney.
No effective backup regime can be created or implemented by an IT support provider in Sydney without a comprehensive survey of your company’s backup needs. However, today’s increasingly complex mix of operating systems, on-site and off-site systems, devices, types of data, networked appliances, physical and virtual platforms, and other considerations can make such a survey a monumental task. Doing it effectively requires skill, experience, and relevant tools. At CustomTec, we can help by providing advice and support. Contact us today to learn more.
