Perhaps I am just missing an obvious section in the documentation, but I am trying to get a better handle on the Percona backup tool(s). This is with particular regard to the ability to have point in time recovery as in the Enterprise Ops Manager.
Currently Percona Backup for MongoDB doesn’t support PITR directly. You can use it for full back ups and then apply the oplog manually.
There’s a blog post here that might help: https://www.percona.com/blog/2019/07/05/mongodb-disaster-snapshot-restore-and-point-in-time-replay/
And also these (older): https://www.percona.com/blog/2016/12/16/mongodb-pit-backups-in-depth/ and https://www.percona.com/blog/2016/09/20/mongodb-point-in-time-backups-made-easy/
If you would like to know when the tool supports PITR, you might find it useful to follow this development log: https://jira.percona.com/browse/PBM-237
Hope this helps?
