Hi folks,
I'm happy to announce that Spotify and TLP have been collaborating to

Handling backups and restore automatically is not an easy task to work on.

Hi guys,
I am trying do a bakup and restore script in a simple way. Is there a way I
can do one command to backup and one to restore a backup?
Or the only way is to create snapshots of all the tables and then restore
one by one?
Hey folks. We (The Last Pickle) have helped a number of clients set up backup
& restore on AWS over the last couple of years. Alain has been working on a
thorough blog post over the last several months to try to document pros, cons
and techniques. Hopefully it proves to be helpful to
schema.

How often snapshots would be created? Shouldn't they be created manually by
nodetool? I haven't created snapshots on the node!

On Thu,
You should be able to follow the same approach(s) as restoring from a
backup as outlined here:

The following should work:

same or a different keyspace).
Hi Jens,
Looks like what you need is an "any point in time" recovery solution. I
suggest that you go back to the snapshot that you issued that was closest
to "20161102" and restore that snapshot using the bulk loader to a new
table called "users_20161102". If you need to recover precisely to a

Hi Jens,
When you refer to restoring a snapshot for a developer to look at, do you
mean restoring the cluster to that state, or just exposing that state for
reference while keeping the (corrupt) current state in the live cluster?
You may find these useful:
https://docs.datastax.com/en/cassandra/2
You would have to build some logic on top of what’s natively supported.
