是否有可能从一个S3存储的所有文件复制到另一个s3cmd？ [英] Is it possible to copy all files from one S3 bucket to another with s3cmd?

问题描述

我是pretty的满意s3cmd，但有一个问题：如何将所有文件从一个S3存储复制到另一个？它甚至有可能？

I'm pretty happy with s3cmd, but there is one issue: How to copy all files from one S3 bucket to another? Is it even possible?

编辑：我已经找到一种方法来复制使用Python与博托桶之间的文件：

I've found a way to copy files between buckets using Python with boto:

from boto.s3.connection import S3Connection

def copyBucket(srcBucketName, dstBucketName, maxKeys = 100):
  conn = S3Connection(awsAccessKey, awsSecretKey)

  srcBucket = conn.get_bucket(srcBucketName);
  dstBucket = conn.get_bucket(dstBucketName);

  resultMarker = ''
  while True:
    keys = srcBucket.get_all_keys(max_keys = maxKeys, marker = resultMarker)

    for k in keys:
      print 'Copying ' + k.key + ' from ' + srcBucketName + ' to ' + dstBucketName

      t0 = time.clock()
      dstBucket.copy_key(k.key, srcBucketName, k.key)
      print time.clock() - t0, ' seconds'

    if len(keys) < maxKeys:
      print 'Done'
      break

    resultMarker = keys[maxKeys - 1].key

正在同步几乎是直线前进的复制。有对ETag的，大小字段，以及用于密钥上次修改可用的

Syncing is almost as straight forward as copying. There are fields for ETag, size, and last-modified available for keys.

也许这可以帮助其他人。

Maybe this helps others as well.
