Cassandra

You can use the Commvault software to back up and restore Cassandra.

Backups

Data You Can Back Up

• All the keyspaces from all the nodes that are in the Cassandra cluster

• User-defined data types

• Transaction logs or commit logs

• Tables with vector data type (Supported from Apache Cassandra 5.x and DSE 6.9.x versions)

Backups You Can Perform

• Full backups

• Incremental backups

• Commit log backups

When You Can Perform Backups

• On a schedule: The backup plan that you assign manages scheduled backups

• On demand: You can perform on-demand backups at any time

Restores

What You Can Restore

• The entire cluster

• Individual key spaces or column families

• Commit logs

• Tables with vector data type (supported from Apache Cassandra 5.x and DSE 6.9.x versions)

Backups You Can Use for Restores

• The most recent backup: For example, restore the most recent backup to its original location

• A backup from a specific date: For example, restore data to a point in time before it became unusable

• Backups from a date range: For example, restore data that was accidentally deleted

Destinations You Can Restore To

• The current location (in place)

  You can restore the data and update the data directory to perform a recovery. Or you can copy the files to the nodes without updating the data directory.

• A different cluster (out of place)
