A small script to backup files and directories to s3 using s3cmd

s3-backup.sh

#!/bin/bash

# you can drop this in cron.hourly or cron.daily, or run it manually.

## relies on an installed and properly configured s3cmd.
## install python-magic to keep s3cmd from throwing warnings.

# set your bucket name here, it can be global for your org as we store any data
# under the hostname.
# note: bucket names are global, so you need to pick something nobody else already picked.
# protip: bucketname is already taken by somebody. :)  

bucket="bucketname"

hostname=`hostname`

# add files to backup here, no trailing slash,
declare -a files=()
# example:
# declare -a files={'/some/file/path' '/another/file/path/' 'yet/one/more/file/path' \
#                   '/use/back/slahes/to/wrap/to/a/new/line' '/leave/a/space/between/entries' \
#                   '/single/or/double/quotes/around/entries' )

# add directories to backup here, no trailing slash.
declare -a dirs=('/etc')

# verify that our bucket exists, if not, make it.
