dsh-backup-retention

Figuring out how much storage a backup policy will eventually consume often boils down to back-of-the-envelope guesswork. dsh-backup-retention replaces that uncertainty with precise arithmetic: you supply the policy parameters and the tool walks through the math step by step, returning every intermediate result so the capacity boundary is crystal clear.

The plugin registers itself as the backup_retention tool inside your session. A single call with the relevant parameters produces a complete calculation breakdown. The implementation is pure Node with zero network calls, which makes it safe to run offline, inside intranet boundaries, or as a node in an existing agent workflow without pulling in extra dependencies.

If you need to periodically project backup growth in an automation pipeline, compare capacity budgets across policy variants, or simply sanity-check what a set of retention parameters implies for total storage footprint, this lightweight utility is built for the job. It is especially well suited to ops and data engineers who prefer local computation and want to keep sensitive parameters off any external API.
