Hello Ivan,
Is there a way I can do one command to backup and one to restore a backup?
Handling backups and restore automatically is not an easy task to work on.
It's not straight forward. But it's doable and some did some tools (with
both open source and commercial licences) do this process (o
You should take a look into ssTableLoader cassandra utility,

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:
https://docs.datastax.com/en/cassandra/2.1/cassandra/operations/ops_backup_snapshot_restore_t.html#ops_backup_snapshot_restore_t

Hi Jens – I put together a couple of simple scripts a couple of years ago
that might do exactly what you need. These leverage nodetool snapshot and
sstableloader to create keyspace snapshots, collect up all the necessary
SSTable files in an easy-to-move file, rename the keyspace, restore it to

The following should work:
1. Create a new table with the same schema but different name (in the
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
par

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.
Here is an option:

And thanks a lot for coming forward with production experience. That
