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.

Important

Backups made with previous versions are incompatible for restore with Percona Backup for MongoDB 1.5.0. This is because processing of system collections users and roles has changed during backup / restore operations. For details, refer to Restoring a backup and PBM-636.

New Features

• PBM-596: Azure Blob Storage support

• PBM-488: Create weight or tag method to influence with pbm-agent node will do backups

Improvements

• PBM-662: Show PITR Status based on admin.pbmLock instead of config settings

• PBM-494: Prefer a (healthy) hidden secondary to any other node in automatic selection

Bugs Fixed

• PBM-642: Display priority=0 members on agent list in pbm status output

• PBM-636: Different collection UUID after restore (Thanks to Nikolay for reporting this issue and Dmitry Kuzmin for contributing)

• PBM-646: Stop the balancer during backup to make sure it doesn’t start running during restore

• PBM-635: Wait for the leader’s metadata before starting backups

• PBM-490: Use cluster time for the snapshot start time
