Dear David Timothy Strauss,

Could you tell me more detail about Backups? As I know, Cassandra data file will compact new data, so it can be changed many times.

How to backup Cassandra data?

Cassandra has always supported two great ways to prevent data loss:

I doubt Cassandra will ever focus extensively on single-node recovery when it's so easy to wipe and rebuild any node from the cluster.

Subject: Cassandra data file corrupt

Dear all,

My Cassandra data file had problem and I can not get data from this file. And all row after error row can not be accessed. So I lost a lot of data.

Will next version of Cassandra implement the way to prevent data lost. Maybe we use the checkpoint. If data file corrupt, we will read from the next checkpoint.

If not, can you suggest me the way to implement this function?

Best regards,
