I have recently inherited 20TB of data after a company takeover. The files are currently stored on an Amazon S3 account which is due to close.
What would be the most cost effective method of exporting all of this data and storing either locally on premises or in the cloud?
My initial thoughts were to use something like Amazon Snowball to send me a physical copy of the data, store half on a new Amazon S3 glacier bucket for infrequent access and the more recent files somewhere else.
Is there a more cost effective way?
