Backup your files to Amazon Web Services in a way that slowly forgets! I've learned that this way is refered to as the 'Grandfather, father, son' strategy.

This script copies a file to Amazon S3 and rotates it.

The filename will have a date stamp added before the first . in the filename. Do not add a timestamp yourself, this will cause the script to treat the file as a unique file and the rotation won't work!

Rotation works as follows:

• Keep files from the last X days
• After that, keep Y files spaced at least a week apart
• After that, keep Z files spaced at least 30 days apart

pip install s3-backup-rotate

Export the following environment variables:

export AWS_ACCESS_KEY_ID=yourkeyidhere
export AWS_SECRET_ACCESS_KEY=yoursecretkey

You can also use one of the other methods supported by boto.

upload_rotate.py bucket prefix file

See python upload_rotate.py -h for more info.
