How to use Percona Backup for MongoDB: going back in time (pbm restore)

In a highly-available architecture, such as MongoDB replication, there is no need to make a backup in order to recover from a problem like a disk failure. If you lose one node you can replace it by re-initializing from one of its replica set peers.

The only point of backups of a replica set is to go back in time. For example, a web application update was released on Sunday, June 9th 23:00 EST but, by 11:23 Monday, someone realizes that the update has wiped the historical data of any user who logged in due to a bug.

Nobody likes to have downtime, but it’s time to roll back: what’s the best backup to use?

$ pbm list --mongodb-uri="mongodb://172.17.0.1:27018"

Output

2019-09-10T07:04:14Z
2019-09-09T07:03:50Z
2019-09-08T07:04:21Z
2019-09-07T07:04:18Z

The most recent daily backup would include 4 hours of damage caused by the bug. Let’s restore the one before that:

$ pbm restore 2019-06-09T07:03:50Z --mongodb-uri="mongodb://172.17.0.1:27018"

Next time there is an application release, it might be best to make an extra backup manually just before:

$ pbm backup --mongodb-uri="mongodb://172.17.0.1:27018"
