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.

New features

• A new rack-list field has been added to backup-routines. It backs up partitions whose master is on a node in the listed racks when the job starts. This field is mutually exclusive with node-list and partition-list, and with cluster-level prefer-racks. prefer-racks still backs up the entire namespace and only affects which replica is read per partition. See Rack-aware backup: prefer-racks vs rack-list.

• A new optional timestamp-format field is available in the service.backup configuration section.

• The backup-policies 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.
