Hi folks, I'm happy to announce that Spotify and TLP have been collaborating to create and open source a new backup and restore tool for Apache Cassandra : https://github.com/spotify/cassandra-medusa It is released under the Apache 2.0 license. It can perform full and differential backups, in

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

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?

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
