What is Backup Retention Policy?
A backup retention policy defines how many backup copies are kept and for how long — commonly a grandfather-father-son scheme of dailies, weeklies, monthlies and yearlies. Retention determines how far back you can recover, which matters when corruption or intrusion is discovered months later.
Why Backup Retention Policy matters for Australian businesses
Data is one of your most valuable business assets, and losing it — whether through ransomware, hardware failure, or natural disaster — can be catastrophic. Understanding backup and disaster recovery concepts ensures you can make informed decisions about protecting your business and recovering quickly when things go wrong.
For small and medium businesses in particular, a backup retention policy can make a real difference in maintaining a secure, efficient, and resilient IT environment. Whether you are reviewing your current setup or planning improvements, understanding the role of a backup retention policy in your broader IT strategy will help you have more informed conversations with your IT provider and make better decisions for your business.

Frequently Asked Questions
What is backup retention?
The schedule of how many recovery points are kept and for how long — for example 30 dailies, 12 weeklies, 24 monthlies and 7 yearly archives.
How long should backups be retained?
Long enough to recover from late-discovered problems and meet legal obligations — many businesses keep months of operational points plus multi-year archives for compliance.
Why not keep everything forever?
Cost and privacy: storage grows endlessly and retained personal data carries obligations. Retention policy balances recoverability against expense and exposure.
