Snapshot
Published 15 January 2025
Description
Generates a snapshot from a database environment, build environment, schema snapshot folder or empty source. A snapshot captures the schema of a specified source into a file for subsequent use with the Check Changes command, Check Drift command, Snapshot command or Snapshot provisioner.
Be sure to set environment schemas when generating a snapshot for Oracle databases.
See Snapshots for more information.
Usage examples
Generating a snapshot from a database URL
flyway snapshot -url=jdbc:sqlserver://localhost:1433;encrypt=false;databaseName=Inventory -user=sa -password=... -filename=C:\snapshot.json
Generating a snapshot from a database environment
if a database environment named dev is configured in the flyway.toml file, then the environment name can be provided as a CLI argument instead of passing the connection details as CLI arguments.
flyway snapshot -source=dev -filename=C:\snapshot.json
Generating a snapshot from a schema snapshot folder
flyway snapshot -source=schemaSnapshot -filename=C:\snapshot.json
Generating a snapshot using the build database
flyway snapshot -source=migrations -buildEnvironment=shadow -buildVersion=2 -filename=C:\snapshot.json
The snapshot.build* arguments make it possible to create a snapshot for any migration version.
