ak backups verify

Recompute manifest hashes and report ok | corrupt

Synopsis

What it does: Recompute the sha256 of every file under the snapshot's data/ tree and compare against the recorded hash. Reports ok only when all entries match.

Who it's for: Power devs validating that a snapshot is safe to restore; CI integrity checks.

When to use it: Before ak backups restore; periodic audits.

Examples: ak backups verify 20260426T123005Z-deadbeef ak backups verify 20260426T123005Z-deadbeef --json

What changes on disk: Read-only.

Output modes: pretty default on TTY (colors, ASCII markers) plain auto when stdout piped or --no-interactive json --json (single-object envelope, NDJSON-safe)

Exit codes: 0 success 1 runtime error 2 invalid flags 3 user-cancel (SIGINT, prompt-cancel) 5 snapshot id not found 1 snapshot is corrupt
