You can do snapshot backup, which is the same as SRDF, by snapping the
LUN(s) and then using file system copy to back it up to an offline
storage like S3 or Glacier. However, I'm no big fan of Glacier. It
should only be used as the storage of the last resort. AWS charges for
getting data out of Glacier and getting data out of Glacier is very,
very slow or even slower than that. The low price of Glacier data is
achieved by using 2-pass deduplication algorithm which shrinks your data
to less than 10% of its initial size, but it means that you also have to
do 2 passes through the deduplication DB to get the data out.
