# `mix tay.storage.backup`
[🔗](https://github.com/AndriiSydorenko1904/tay/blob/v1.6.1/lib/mix/tasks/tay.storage.backup.ex#L1)

Creates an exclusive cold backup of a stopped Tay store.

    mix tay.storage.backup --source /store --destination /backup --catalog /backup.json --durability development

The default `--durability sync` requires `--validated-filesystem` and a
supported persistent Linux filesystem. The destination and catalog must not
exist; failed staging is retained for inspection.
