Pre-Reqs

Supported Services

You MUST use one of these services in order to use this plugin to dump/restore backups. The list of services is:

• AWS-RDS/MySQL

Supported Storage

You MUST be able to create one of these services in order to stream the backup. The list of the services that can store the data is:

• S3

Commands

There are five commands:

cf export-data

Creates a backup your data

Interactively creates an application, binds to your service, streams the data from your service to a S3 bucket.

Usage:

cf export-data

Note

You will need to already have the S3 bucket created. If you do not have it, you can do so by running:

cf create-service s3 basic YourS3BackupNameHere

cf import-data

Restores a backup of your data

Interactively creates an application, binds to your new service, streams the data from the S3 bucket to the new service.

Usage:

cf import-data

cf download-backup-data

Download a backup to your local computer

Interactively selects the backup data from an existing exported data dump (must run cf export-data first) and downloads it locally to your computer.

Usage:

cf download-backup-data

cf upload-backup-data

Uploads a backup from your local computer

Uploads a local file into an existing exported data dump (must run cf export-data first). It will get renamed appropriately upon upload automatically.

Usage:

cf upload-backup-data -p <file_path> [-store <name_of_s3_service>]

Note: Providing the optional -store flag will run this command in non-interactive mode.

cf clean-export-config

Cleans your config file and create a new one.

Usage:

cf clean-export-config
