This document demonstrates how to back up juju. A backup of the client enables one to regain management control of one’s controllers and associated cloud environments.

Create a backup of the Juju client

Making a copy of the client directory is sufficient for backing up the client. This is normally done with backup software that compresses the data into a single file (archive). On a Linux/Ubuntu system, the tar program is a common choice:

cd ~
tar -cpzf juju-client-$(date "+%Y%m%d-%H%M%S").tar.gz .local/share/juju 

For Microsoft Windows any native Windows backup tool will do.

The above invocation embeds a timestamp in the generated archive’s filename, which is useful for knowing when a backup was made. You may, of course, call it what you wish.

The archive should normally be transferred to another system (or at the very least to a different physical drive) for safe-keeping.

Whoever has access to a client backup will have access to its associated environments. Appropriate steps should be taken to protect it (e.g. encryption).

Restore the Juju client from a backup

Restoring your client settings is a simple matter of extracting the backup created earlier. For Ubuntu:

cd ~
tar -xzf juju-yymmdd-hhmmss.tar.gz 

This command will extract the contents of the archive and overwrite any existing files in the Juju directory. Make sure that this is what you want.
