Astra DB guardrails for classic databases

For serverless database guardrails, see Astra DB limits for serverless databases.

DataStax Astra DB includes guardrails to ensure good practices and promote optimal database configurations.

Automated backup and restore

Classic databases created using Astra DB are automatically backed up every four hours. The latest six snapshots are stored, providing flexibility in which point in time you can restore to, if necessary.

If the database was terminated, all data is destroyed and is unrecoverable.

If data is accidentally deleted or corrupted, contact DataStax Support within 12 hours to restore data from one of these snapshots. This window ensures that the data to restore exists as a saved snapshot.

When restoring data, DataStax Support allows you to restore data on the same cluster if the table is dropped, and data is restored in the same cluster using the specified backup.

Limited access to administrative tools

Because Astra DB hides the complexities of database management to help you focus on developing applications, Astra DB is not compatible with DataStax Enterprise (DSE) administrative tools, such as nodetool and dsetool.

Use the DataStax Cloud console to get statistics and view database and health metrics. Astra DB does not support access to the database using the Java Management Extensions (JMX) tools, like JConsole.

Simplified security without compromise

Astra DB provides a secure cloud-based database without dramatically changing the way you currently access your internal database:

  • New user management flows avoid the need for superusers and global keyspace administration in CQL.

  • Endpoints are secured using mutual authentication, either with mutual-TLS or secure tokens issued to the client.

  • TLS provides a secure transport layer you can trust, ensuring that in-flight data is protected.

  • Data at rest is protected by encrypted volumes.

Additionally, Astra DB incorporates advanced DSE features like role-based access control (RBAC) and row-level access control (RLAC).

See Security guidelines for more information about how Astra DB implements security.

Replication within regions

Each Astra DB database uses replication across three availability zones within the launched region to promote uptime and ensure data integrity.

Storage-Attached Indexing (SAI) limits

The maximum number of SAI indexes on a table is 10. There can be no more than 100 SAI indexes in a single database.
