Aerospike Backup Service 3.4.0 release notes

November 5, 2025 | Download

This release delivers bug fixes and incremental improvements based on customer feedback. The primary addition is rack‑aware backups.

Breaking changes

The prefer-racks configuration field has moved from the backup routines section to the Aerospike clusters section of the configuration file.

A new rack-list field has been added to the backup routines It specifies a list of racks to back up. Only nodes belonging to the specified racks are scanned. This field is mutually exclusive with prefer-racks, node-list, and partition-list.
A new optional timestamp-format field is available in a new configuration section, service.backup.
The backup policy section adds two optional fields:
- max-concurrent-nodes — Maximum number of concurrent requests to server nodes. Default: issue requests to all nodes in parallel.
- use-scan-compression — Enables built‑in compression during scan operations (Aerospike Server Enterprise Edition only). Both fields are optional; they do not change functionality but may affect performance.
