Upload backups to Amazon S3 bucket using boto, Python

Here is a script to upload backups older than 1 day to S3 bucket. We would like to exclude transaction log backups so I used "if 'LOG' not in name" - you may change it accordingly.

import os, sys, time
from boto.s3.connection import S3Connection
from boto.s3.key import Key
conn = S3Connection('YOURKEY','SECRETKEY')
bucket = conn.get_bucket('MyBeautifulBucket')
age = 86400 #1 day = 24*60*60
backupdir = 'O:\Backups\'

for root, dirs, files in os.walk(backupdir, topdown=False):
    for name in files:
        if 'LOG' not in name: #exclude copying transaction log backups
            f = os.path.join(root, name)
            now = time.time()
            modified = os.stat(f).st_mtime
            if modified > now - age:
                k=Key(bucket)
                k.key= 'mySubBucket/' + str(name)
                k.set_contents_from_filename(f)
