Estimate backup storage requirements from website size, backup frequency, retention period and expected compression or incremental efficiency.
Enter your values and calculate.
This is a planning estimate based on the values you enter. Real WordPress environments can be affected by disk speed, database size, cache behavior, provider limits, plugin architecture, active traffic and third-party services. Verify the production environment before making a live change.
A backup stored only on the same hosting account does not protect you from account suspension, disk failure, destructive malware or accidental deletion of the entire environment. Keep at least one independent copy.
Use the calculator as a planning aid, then validate the result against the actual WordPress installation, hosting account and production traffic. These notes explain the technical assumptions behind the result and the checks I would make before acting on it.
A useful backup plan includes multiple restore points and preferably off-server copies. If the only backup lives on the same account as the website, a server failure, compromise or account suspension can remove both at once.
Full backups are easy to understand but consume more storage. Incremental systems can reduce storage by saving only changed data after a base snapshot. The actual space used depends on how the provider deduplicates data.
A store can create new orders, customer accounts and stock changes every minute. A once-daily backup may represent too much potential data loss. Recovery-point objectives should reflect how much new transactional data the business can afford to lose.
Backup success notifications do not prove that recovery works. Periodically restore to staging and verify database integrity, media, logins, checkout, email and scheduled jobs.
No. It is an estimate based on the inputs available in a browser. Production WordPress sites can have custom code, unusual server limits, third-party integrations and traffic patterns that change the real requirement.
The calculator runs in your browser. The page does not need an account or a database to calculate the result. Avoid pasting passwords, API keys or private customer information into any planning field.
Use a manual review when the site generates revenue, has active users, contains a large database, uses memberships or subscriptions, has custom integrations, or cannot tolerate an extended rollback window.
The useful part of a planning tool is not the number by itself. It is understanding which assumptions produced the result, which production conditions can change it, and what should be checked before you act. Use this tool as part of a wider migration or infrastructure review rather than as an automatic go/no-go decision.
Hosting decisions depend on CPU time, memory, disk I/O, PHP workers, database behavior, cache hit rate, file count and operational limits. A single storage or memory value should be treated as one part of the environment.
Backups, archives, temporary extraction directories and database dumps can briefly require far more disk space than the live site itself. Planning without temporary headroom is a common reason migrations fail part-way through.
Shared and managed platforms can impose inode, process, upload, execution-time, cron, database or outbound-transfer limits. Compare the estimate with the real plan limits before committing to a production move.
Treat it as a planning starting point with operational headroom. Real requirements depend on workload and provider limits.
Migration archives, extraction copies and backups may coexist with the live site. That can temporarily double or triple storage demand.
No. Dynamic requests, PHP workers, database load, admin activity, WooCommerce and cacheability can matter more than raw visitor count.
