  1. If not, what is the right  backup strategy ?
You didn't specify, but it sounds like you are doing a snapshot and then a full offhost backup of the sstables?

Perhaps instead of point in time full backups, you could continuously back up with something like tablesnap [1]? tablesnap watches the datadir for newly created SSTables and then writes the file and a manifest containing which other files were also in the directory at the time. These two pieces of information allow you to restore to the point in time when any given (immutable) data file was created.
