 print "Remove success"

 print "Start put OSS"

 import shutil
 import oss2

 access_key_id = ''
 access_key_secret = ''
 bucket_name = 'x-backup'
 endpoint = 'oss-cn-hangzhou-internal.aliyuncs.com'

 bucket = oss2.Bucket(oss2.Auth(access_key_id, access_key_secret), endpoint, bucket_name)
 bucket.put_object_from_file('mysql/'+DATETIME+'.tar.gzip',compress_file)
 print "Put OSS success"

再加上crontab 就搞定了

crontab -e
