Re: Nodetool hanging - Cassandra 3.10, Oracle Java 1.8.0_131

[Roger Brown]

My first thought is restart cassandra and monitor its log to make sure it
starts up.

Tablesnap with custom endpoint?

[Roger Brown]

I wanted to use tablesnap for backups. Instead of s3.amazonaws.com, I
wanted to use our own s3-compatible endpoint. I could never figure it out.
Do you know how to override the S3 endpoint tablesnap uses?

Re: Any Cassandra Backup and Restore tool like Cassandra Reaper?

[Roger Brown]

I've found nothing affordable that works with vnodes. If you have money,
you could use DataStax OpsCenter or Datos.io Recoverx.

I ended up creating a cron job to make snapshots along with
incremental_backups: true in the cassandra.yaml. And I'm thinking of
setting up a replication strategy so that one rack contains 1  replica of
each keyspace and then using r1soft to image each of those servers to tape
for offsite backup.

Re: Datastax pricing

[Roger Brown]

DataStax should be the one to tell you. I talked to them earlier this week
and they respond quickly.
