Hi, At present, it looks like the PSMDB operator for Kubernetes offers only full backup support. It takes several Megabytes of S3 storage to maintain multiple backups for a longer period of time. Is there any plan to provide incremental backup support in any of the upcoming releases? ---

Hello @siva , the problem you are trying to solve is the storage consumption, right? Our Operator also supports point-in-time recovery - uploading oplogs to S3. Do you think it helps? ---

Hello again @Sergey_Pronin! At risk of unearthing an old conversation, I thought it would be better to comment here rather than create a duplicate topic. I could not find anything in the operator docs referring to incremental backups, so I’m assuming only full and PITR backups are supported currently. Our use-case involves a big cluster (let’s say 1TB for simplicity’s sake) which grows a few GB every day. Doing one full backup and then enabling PITR is not ideal as the recovery time would be way too long, and creating full backups every N days would be expensive (mostly in terms of bandwidth, storage cost isn’t that much of an issue) so incrementals seem like a good way to go about it. From my understanding, incremental backups are considered a _Technical preview feature_, but as they’ve been around for a couple years now, I was wondering if there’s anything blocking their implementation into the Mongo Operator. ---

Hello @Semantic , no problem with unearthing 🙂 Operator does not have incremental backups yet. We use Percona Backup for MongoDB (PBM) in the Operator and it added incremental backups only just now for physical: [Incremental physical backups - Percona Backup for MongoDB](https://docs.percona.com/percona-backup-mongodb/usage/incremental-backup.html) We don’t have logical incremental backups, just PITR (oplogs). We will add physical backups in the next release of the operator. Will see if we can add incremental in the same go. ---

@Sergey_Pronin Ah, my apologies. I assumed that the OP mentioning incremental backups meant they were already out there when he posted about it, but `2.0.3` was indeed created 2 weeks ago. Let me know if there’s anything I can help with to have it make it to the operator release! I’ll definitely be happy to try it out and report my findings. I think [K8SPSMDB-713](https://jira.percona.com/projects/K8SPSMDB/issues/K8SPSMDB-713) might actually be related since it adds support for physical backups to the operator, although does not seem to touch on incrementals, as it was opened last July. ---

@Semantic we have this huge pull request for physical backups and restores: [https://github.com/percona/percona-server-mongodb-operator/pull/1112](https://github.com/percona/percona-server-mongodb-operator/pull/1112) You can check if it would be easy to add incremental backups. What do you think? ---

Not sure if this is sarcasm, but yes I know, that PR is related to [K8SPSMDB-713](https://jira.percona.com/projects/K8SPSMDB/issues/K8SPSMDB-713) I linked above. Given Ege already added the `backupType` option, the thing missing is supporting passing the `--base` param required when creating the first incremental backup which acts exactly the same as a full physical backup. Since _pbm_ should handle creating the incremental based on what changed, I’m assuming adding a backup task entry to run the incremental on a schedule should work as expected. I’m sure there might be some other considerations like writing the unit tests for it, but from it doesn’t seem that extreme of an add. ---

No sarcasm at all, I was not sure if you saw the PR 🙂 I will ask Ege about it and see. Thanks for pushing it forward!
