Configuration

Snapshot is configured using a snapshot.yml file.

You can also pass --config or -c to specify the exact config filename you wish to use.

To get you started, simply run:

cp snapshot.yml.dist snapshot.yml

and edit snapshot.yml to fit your environment

Example snapshot.yml

In the following config you'll find 2 configured database servers (server-a and server-b), and one storage backend (store1):

workdir: /snapshot

servers:
  
  server-a:
    username: root
    password: super_secret_password
    address: 10.0.0.100
    port: 3306
    
  server-b:
    username: root
    password: mega_secret_password
    address: 10.0.0.101
    port: 3306
    
    
storage:
  store1:
    type: s3
    region: eu-west-1
    access_key: HELLO
    secret_key: SHHHHHHH
    bucket: my_bucket_name
    prefix: "snapshot/"
    gpg_password: s3cr3t

Usage examples:

Backing up a whole server:

The following command will backup all databases on server-a to store1.

bin/snapshot server:backup server-a store1

Backing up a single database:

The following command will backup database my_db on server-a to store1.

bin/snapshot database:backup server-a my_db store1

List remote snapshots

The following command will list all snapshots in store1.

bin/snapshot snapshot:list store1

The following command will list all snapshots in store1 matching a filter.

bin/snapshot snapshot:list store1 snapshot-a/*/my_db

Restoring backups

The following command will restore a backup of snapshot server-a/20160101/my_db from store1 onto server-b:
