Storage Providers

gptBuster supports remote and local storage providers for handling file uploads in forms and storing database snapshots.

Supported Providers

The following storage providers are currently supported:

AWS S3

To use AWS S3 or any S3-compatible service (e.g., MinIO, Cloudflare R2), set the following environment variables:

  • STORAGE_PROVIDER=s3
  • STORAGE_S3_BUCKET
  • STORAGE_S3_ACCESS_KEY_ID
  • STORAGE_S3_SECRET_ACCESS_KEY
  • STORAGE_S3_REGION
  • STORAGE_S3_ENDPOINT (optional; use for custom endpoints or S3-compatible services)

Azure Blob Storage

To use Azure Blob Storage, set the following environment variables:

  • STORAGE_PROVIDER=azure
  • STORAGE_AZURE_CONTAINER
  • STORAGE_AZURE_CONNECTION_STRING

Local File System

By default, Sentinel uses the local file system for storage. Files are stored in the data directory.

  • STORAGE_PROVIDER=local (default)
  • STORAGE_LOCAL_DIR (defaults to {DATA_DIR}/storage)

Snapshots

Database snapshots can use a different storage provider than the one used for file uploads. To configure this, use the same environment variables as above, prefixed with SNAPSHOTS_. For example:

  • SNAPSHOTS_STORAGE_PROVIDER
  • SNAPSHOTS_STORAGE_S3_BUCKET
  • SNAPSHOTS_STORAGE_S3_ACCESS_KEY_ID
  • SNAPSHOTS_STORAGE_S3_SECRET_ACCESS_KEY
  • SNAPSHOTS_STORAGE_AZURE_CONTAINER
  • SNAPSHOTS_STORAGE_LOCAL_DIR

This separation allows you to store snapshots independently of form uploads—ideal for backup and redundancy strategies.
