here are the main techniques that I know of to perform backups for
Cassandra :

   - Tablesnap (https://github.com/JeremyGrosser/tablesnap) : performs
   continuous backups on S3. Comes with tableslurp to restore backups (one
   table at a time only) and tablechop to delete outdated sstables from S3.
   - incremental backup : activate it in the cassandra.yaml file and it
   will create snapshots for all newly flushed SSTables. It's up to you to
   move the snapshots off-node and delete them. I don't really like that
   technique since it creates a lot of small sstables that eventually contain
   a lot of outdated data. Upon restore you'll have to wait until compaction
   catches up on compacting all the history (which could take a while and use
   a lot of power). Your backups could also grow indefinitely with this
   technique since there's no compaction, so no purge. You'll have to build
   the restore script/procedure.
   - scheduled snapshots : you perform full snapshots by yourself and move
   them off node. You'll have to build the restore script/procedure.
   - EBS snapshots : probably the easiest way to perform backups if you are
   using M4/R4 instances on AWS.
