B2 Backup And Restore
When to use
- The user asks to back up a directory, application export, database dump, model artifact, or media set to Backblaze B2.
- The user asks to restore or verify previously backed up B2 objects.
- The user needs a repeatable backup runbook that separates metadata planning from object byte transfer.
Byte path
- Object data MUST move directly between the client or workload runner and B2 using presigned URLs, multipart upload URLs, or an external B2/S3 client.
- MUST NOT route object data through the model or MCP server. Use MCP only for bucket discovery, metadata checks, presigned URL creation, manifest planning, and bounded status.
- Manifest and sidecar bytes use the same out-of-band direct path as backup data. MCP may track names, checksums, and status only; do not send manifest or sidecar contents through chat or server inline helpers.
