A monkey that makes sure you have a backup of your EBS volumes in case something goes wrong.
It is designed specifically for Amazon Web Services (AWS), and uses Python and Boto.
This script is designed to be run on a schedule, probably by CRON.
usage: backup-monkey [-h] [--region REGION] [--max-snapshots-per-volume SNAPSHOTS] [--snapshot-only] [--remove-only] [--verbose] [--version] [--tags TAGS [TAGS ...]] [--reverse-tags] [--label LABEL] [--cross-account-number CROSS_ACCOUNT_NUMBER] [--cross-account-role CROSS_ACCOUNT_ROLE] Loops through all EBS volumes, and snapshots them, then loops through all snapshots, and removes the oldest ones. optional arguments: -h, --help show this help message and exit --region REGION the region to loop through and snapshot (default is current region of EC2 instance this is running on). E.g. us-east-1 --max-snapshots-per-volume SNAPSHOTS the maximum number of snapshots to keep per EBS volume. The oldest snapshots will be deleted. Default: 3 --snapshot-only Only snapshot EBS volumes, do not remove old snapshots --remove-only Only remove old snapshots, do not create new snapshots --verbose, -v enable verbose output (-vvv for more) --version display version number and exit --tags TAGS [TAGS ...] Only snapshot instances that match passed in tags. E.g. --tag Name:foo will snapshot all instances with a tag `Name` and value is `foo` --reverse-tags Do a reverse match on the passed in tags. E.g. --tag Name:foo --reverse-tags will snapshot all instances that do not have a `Name` tag with the value `foo` --label LABEL Only snapshot instances that match passed in label are created or deleted. Default: None. Selected all snapshot. You have the posibility of create a different strategies for daily, weekly and monthly for example. Label daily won't deleted label weekly. E.g. backup-monkey --max-snapshots-per-volume 6 --label daily backup-monkey --max-snapshots-per-volume 4 --label weekly You save 6 + 4 snapshots max. instead 4 or 6 --cross-account-number CROSS_ACCOUNT_NUMBER Do a cross-account snapshot (this is the account number to do snapshots on). NOTE: This requires that you pass in the --cross-account-role parameter. E.g. --cross-account-number 111111111111 --cross-account- role Snapshot --cross-account-role CROSS_ACCOUNT_ROLE The name of the role that backup-monkey will assume when doing a cross-account snapshot. E.g. --cross- account-role Snapshot
Create snapshots of all EBS volumes in us-east-1:
backup-monkey --region us-east-1
Delete snapshots of EBS volumes in us-west-1 where a volume has more than 5 snapshots:
backup-monkey --region us-west-1 --max-snapshots-per-volume 5 --remove-only
You can install Backup Monkey using the usual PyPI channels. Example:
sudo pip install backup_monkey
You can find the package details here: https://pypi.python.org/pypi/backup_monkey
Alternatively, if you prefer to install from source:
git clone firstname.lastname@example.org:Answers4AWS/backup-monkey.git cd backup-monkey python setup.py install
This project uses Boto to
call the AWS APIs. You can pass your AWS credentials to Boto can by using a
.boto file, IAM Roles or environment variables. Full information can be
python -m unittest -v tests.unit.test_exceptions python -m unittest -v tests.unit.test_tags
Make no mistake. This script WILL delete snapshots. This script WILL create snapshots, which can cost you money. There really are no warranties or guarantees. For costs, refer to http://aws.amazon.com/ec2/pricing/
The Python source code for Backup Monkey is available on GitHub:
