Backup

For backup purposes, we recommend using Amazon S3 to keep a copy of HDFS data from instance stores. Amazon S3 stores data objects redundantly on multiple devices across multiple facilities and allows concurrent read or write access to these data objects by many separate clients or application threads. You can use the redundant data stored in Amazon S3 to recover quickly and reliably from instance or application failures.
