automated-ebs-snapshots

Maintainability

Automated EBS Snapshots helps you ensure that you have up to date snapshots of your EBS volumes.

All you need to do to get started is documented below.

Installation

pip install automated-ebs-snapshots

Authentication configuration

IAM Policy

First you need to create an IAM user and give that user correct Permissions. Below is an example policy:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "Stmt1453988686666",
            "Effect": "Allow",
            "Action": [
                "ec2:CreateSnapshot",
                "ec2:CreateTags",
                "ec2:DeleteTags",
                "ec2:DeleteSnapshot",
                "ec2:DescribeSnapshots",
                "ec2:DescribeVolumes"
            ],
            "Resource": [
                "*"
            ]
        }
    ]
}

Automated EBS snapshots can be configured either via command line options or using a configuration file.

Command line options

You can use the following command line options to authenticate to AWS.

AWS configuration options:
  --access-key-id ACCESS_KEY_ID
                        AWS access key
  --secret-access-key SECRET_ACCESS_KEY
                        AWS secret access key
  --region REGION       AWS region

Configuration file

Create a configuration file anywhere on you file system. If parameters for access-key-id and secret-access-key are not defined, the instance's IAM role will be used instead.

[general]
access-key-id: xxxx
secret-access-key: xxxxxxxx
region: eu-west-1

Then use the --config command line option to point at your configuration file.

Watching and unwatching volumes

Start watching a volume

In order to enable automatic snapshots, you need to start watching the volume. The following command will add vol-13245678 to the watchlist with snapshots created daily.

automated-ebs-snapshots --config ~/auto-ebs-snapshots.conf --watch vol-12345678 --interval daily

Add volumes to watch list

To add lots of volumes in one time, we can create a configuration file to define volumes(support volume id or Name tag), interval and retention.

vol-d9d6d6af,weekly,2
volume1,weekly,4
volume2,daily,0

Then run the following command

automated-ebs-snapshots --config ~/auto-ebs-snapshots.conf --watch-file volumes.conf

List watched volumes

List the currently watched volumes and their backup interval

automated-ebs-snapshots --config ~/automated-ebs-snapshots.conf --list

Stop watching a volume

To stop creating automated backups for a volume, run this:

automated-ebs-snapshots --config ~/automated-ebs-snapshots.conf --unwatch vol-12345678

Remove volumes from watch list

To remove all volumes in the configuration file, just run:

automated-ebs-snapshots --config ~/auto-ebs-snapshots.conf --unwatch-file volumes.conf

List snapshots for a volume

List all snapshots for the given volume id or volume name

automated-ebs-snapshots --config ~/automated-ebs-snapshots.conf --snapshots vol-d9d6d6af

Creating snapshots

Now, to start taking snapshots you will need to have Automated EBS Snapshots running. You can either run automated-ebs-snapshots manually (i.e. scheduled in crontab or such) or have it running in daemon mode.

Manual execution

Running automated-ebs-snapshots manually:

automated-ebs-snapshots --config ~/automated-ebs-snapshots.conf --run

It will check if there are any volumes with no or too old snapshots. New snapshots will be created if needed.

Force run

It's possible to force run the command by using the --force-run parameter:

automated-ebs-snapshots --config ~/automated-ebs-snapshots.conf --force-run

Daemon mode

Start the daemon by running

automated-ebs-snapshots --config ~/automated-ebs-snapshots.conf --daemon start

Stop the daemon with

automated-ebs-snapshots --config ~/automated-ebs-snapshots.conf --daemon stop

You can also restart it using

automated-ebs-snapshots --config ~/automated-ebs-snapshots.conf --daemon restart
