Percona Backup for MongoDB 2.5.0 (2024-05-16)

Installation

Percona Backup for MongoDB is a distributed, low-impact solution for creating consistent backups of MongoDB sharded clusters and replica sets, and for restoring those backups to a specific point in time.

Release Highlights

  • You can now restore the desired subset of custom databases with users and roles created in them. This is useful for deployments where each user has an individual database and authenticates against it.
  • Previous versions of PBM required that readConcern and writeConcern are set to majority in MongoDB. You can now explicitly override this behavior, and thus, ensure backups in clusters configured to operate without the majority or lost it for some reason.

New Features

  • PBM-1159 - Make ReadConcern configurable
  • PBM-799 - Make WriteConcern configurable
  • PBM-1213 - Restore users and roles in custom databases during a selective restore

Bugs Fixed

  • PBM-1257 - Fixed the issue with PBM failing on running the pbm describe-backup command.

  • PBM-1258 - Improved the resync from storage logic to be triggered only upon changes in the configuration file.
