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
