How to upload multiple files(20K+) to AWS S3

How to upload multiple files to AWS S3?

I tried two ways and both failed:

1)s3cmd shows following error even the file is only 270KB. 

   $s3cmd put file_2012_07_05_aa.gz  s3://file.s3.oregon/
   file_2012_07_05_aa.gz -> s3://file.s3.oregon/file_2012_07_05_aa.gz  [1 of 1]
   45056 of 272006    16% in    1s    25.62 kB/s  failed
   WARNING: Upload failed: /file_2012_07_05_aa.gz ([Errno 32] Broken pipe)
   WARNING: Retrying on lower speed (throttle=0.00)
   WARNING: Waiting 3 sec...

2) use boto's S3 interface.

The boto library is working fine for me only when I create bucket using "US Standard", if I choose other regions like Oregon, it will fail and displays "Connection reset by peer"

def connect_to_s3(access_key, secret_key):
    conn = S3Connection(access_key, secret_key)
    return conn


def percent_cb(complete, total):
    sys.stdout.write('.')
    sys.stdout.flush()

def upload_to_s3(bucket, file_name):
    key = bucket.new_key(file_name)
    key.set_contents_from_filename(file_name,cb=percent_cb, num_cb=10)

My personal favorite solution is using CyberDuck. You log in with S3 API Key credentials, and it works just like a file system explorer. If you drag your folder with your 20000 files, it will upload them just like that. Downloading is just as simple.

Alternatively you could use Minio Client aka mc

using mc mirror this can be achieved

 
$ mc mirror localdir S3alias/remotebucket

If due to network issue or throttling disconnection happens, Minio Client will start the upload from where it left last like.

mc:  Session safely terminated. To resume session ‘mc session resume yarbWRwf’

Hope it helps.

Dasclaimer: I work for Minio

Broken pipe errors have historically happened when the socket_timeout value was too low. Please check your ~/.s3cfg file to ensure socket_timeout = 300 is set.

The default was changed from 10 seconds to 300 seconds in:

* S3/Config.py: Increase socket_timeout from 10 secs to 5 mins.
