Frequently asked questions

A rough starting point is your total data volume multiplied by your retention period and daily change rate, since incremental backups only store what has changed. Most UK SMEs with 500GB-2TB of active data end up needing 2-4x that in backup storage once versioning and retention are factored in.

There is no single UK legal minimum, but common practice is 30-90 days for operational recovery, with many regulated industries (finance, healthcare) requiring 6-7 years for financial or client records under HMRC and GDPR-adjacent obligations. Retention policy should be set by your specific compliance needs, not just storage cost.

The 3-2-1 rule means keeping three copies of your data, on two different media types, with one copy stored off-site. For most UK SMEs this translates to a local NAS backup plus a cloud backup with a separate provider, protecting against hardware failure, ransomware, and site-level disasters like fire or flood.

Version retention is usually the culprit - each incremental backup keeps a snapshot, and if old versions are not automatically purged after your retention window, storage climbs indefinitely. This calculator estimates realistic growth so you can set retention policies before storage costs spiral.
