Base URL: https://api.sevalla.com/v3. Authenticate with an API key in the Authorization header as a Bearer token. > The OpenAPI spec is at https://api.sevalla.com/v3/openapi.json. Concepts and dashboard guides are at https://docs.sevalla.com (index: https://docs.sevalla.com/llms.txt). > To act on a Sevalla account from an AI agent, prefer the Sevalla MCP server (https://mcp.sevalla.com/mcp, see https://docs.sevalla.com/ai-agents/overview.md) or the Sevalla CLI (https://api-docs.sevalla.com/v3/cli.md). # Create database backup target > Attach a backup target to a database. A backup target is an S3-compatible bucket that receives scheduled and manual dump backups. Point it at a Sevalla object storage bucket with `object_storage_id`, or at any external S3-compatible storage with `bucket_name`, `access_key` and `secret_key`. The target configuration is applied to the database asynchronously; scheduled backups start once the apply completes. A database can have up to 5 backup targets. The database and its backups must be in a ready state. Databases that do not support external backups return a 400. ## OpenAPI ````yaml https://api.sevalla.com/v3/openapi.json post /databases/{id}/backup-targets openapi: 3.1.0 info: title: Sevalla API docs version: 1.0.0 servers: - url: https://api.sevalla.com/v3 security: - bearerAuth: [] paths: /databases/{id}/backup-targets: post: tags: - Databases summary: Create database backup target description: >- Attach a backup target to a database.
