Data Backends

Plik supports multiple storage backends for uploaded files.

File (Default)

Stores files in a local or mounted filesystem directory.

DataBackend = "file"
[DataBackendConfig]
    Directory = "files"

Amazon S3

Compatible with any S3-compatible storage (AWS, MinIO, etc.).

DataBackend = "s3"
[DataBackendConfig]
    Endpoint = "s3.amazonaws.com"
    AccessKeyID = "your-access-key"
    SecretAccessKey = "your-secret-key"
    Bucket = "plik"
    Location = "us-east-1"
    Prefix = ""
    UseSSL = true
    PartSize = 16777216  # 16MiB chunks (min 5MiB, max file = PartSize × 10000)
