Steve Loughran commented on SOLR-9952:
--------------------------------------

Constantin; using s3a:// doesn't mean using HDFS. Only that Solr is using the 
Hadoop filesystem APIs to make S3 look like the other filesystems it works 
with, and supports the various work done there on credential management, 
uploads, failure recovery, etc.

I'd be surprised if you could get faster backups, as generally the bottleneck 
is the upload bandwidth. If copying from local files, use 
FileSystem.copyFromLocalFile() and it hands off straight to the aws-sdk bulk 
uploader
