Is it possible to manually backup a Cassandra node?

[GabrielPrioli]

Hello forum,

Suppose a customer is running a Dynatrace Managed cluster with X amount of space for Cassandra, but they want to replicate this to a different area where they would have more space, or for backing up.

1. is this possible? is the cassandra node accessible?

2. would they be able to access the data without the cassandra node being inside a cluster node?

Hi,

Typically, in case an administrator wants to manage disk space effectively and increase the data store size, it is recommended to mount a bigger volume/partition under the same path that was configured as a data store. Before they need to stop the node, mount data store, and start it again.

Backups are a separate story, the path is configurable in Cluster Management Console settings.

Re 1 & 2: Cassandra is always installed on the cluster node.

Does it answers your questions?
