tens3 : dead simple s3 backups

• uses s3 to backup a directory of files

• uses fadvise to be easy on filesystem caches and disks

• purges files after X days

• streams files rather than loading them entirely into memory

license:

This code is available as Open Source Software under the MIT license.

ruby dependencies:

fadvise right_aws

configuration:

tens3.yml:

amazon_access_key_id: “someid” amazon_secret_access_key: “somekey” backup_dir: “/some/path/” purge_threshold: 3 bucket_name: “somebucket”

usage:

backup a directory of files:

$ ./tens3_put tens3.conf

restore a file from a backup:

$ ./tens3_get tens3.conf date somefile ./somefile

The date is the date that the file was backed up in a YYYYMMDD format.

caveats:

The script will only backup files at one directory level, it does not recurse into subdirectories.
