Percona Backup for MongoDB 1.8.0 (2022-06-09)

Release date June 9, 2022
Installation Installing Percona Backup for MongoDB

Percona Backup for MongoDB is a distributed, low-impact solution for consistent backups of MongoDB sharded clusters and replica sets. This is a tool for creating consistent backups across a MongoDB sharded cluster (or a single replica set), and for restoring those backups to a specific point in time.

Release Highlights

  • Ability to restore data to a replica set with a different name and configuration. This extends the list of environments compatible for the restore.

  • When you use EBS-snapshots or other tools for physical backups, you no longer have to create a mandatory base backup snapshot in |Percona Backup for MongoDB| as the starting point for Point-in-Time Recovery oplog slicing. This reduces time and effort on managing excessive backups and makes Point-in-Time Recovery from physical or storage-level backups more straightforward.

  • The ability to wait for the backup operation to finish before doing further actions through the session lock. This simplifies the automation of operations with Percona Backup for MongoDB.

  • Ability to define backup compression level and method in Percona Backup for MongoDB configuration.

  • To simplify the Percona Backup for MongoDB configuration, the example configuration file is now included in the Percona Backup for MongoDB package.

  • Ubuntu 22.04 (Jammy Jellyfish) is added to the list of supported platforms

New Features

  • PBM-776: Allow data restore into the replica set with a different name

  • PBM-866: Add the ability to wait for the backup operation to finish and print the result

  • PBM-782: Allow saving Point-in-Time Recovery oplog without base snapshot

  • PBM-838: Add the ability to configure default compression method and level for backups

Improvements

  • PBM-828: Add the full reference configuration file to packages

  • PBM-751: Format timestamps according to RFC3339 (Thanks to Damiano Albani for reporting this issue)

Bugs Fixed

  • PBM-820: Fix a bug where PBM crashed if backup cancelled right after it started by cancelling the backup gracefully
