Hi, 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 Comes with tableslurp to restore backups (one table at a time only) and tablechop to delete outdated sstables from S3.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 I don't really like that technique since it creates a lot of small sstables that eventually contain a lot of outdated data.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.
