How to clone a key in Amazon S3 using Python (and boto)?

Question

I have a file contained in a key in my S3 bucket. I want to create a new key, which will contain the same file. Is it possible to do without downloading that file? I'm looking for a solution in Python (and preferably boto library).

Answer 1

Where bucket is the destination bucket:

bucket.copy_key(new_key,source_bucket,source_key)

Answer 2

from boto.s3.key import Key

#Get source key from bucket by name
source_key = source_bucket.get_key(source_key_name)

#Copy source key to a new bucket with a new key name (can be the same as source)
#Note: source_key is Key
source_key.copy(dest_bucket_name,dest_key_name)

#The signature of boto's Key class:
def copy(self, dst_bucket, dst_key, metadata=None,
             reduced_redundancy=False, preserve_acl=False,
             encrypt_key=False, validate_dst_bucket=True)

#set preserve_acl=True to copy the acl from the source key
