I have had a difficult time figuring out if fileCopyBased initialSyncMethod is supported in Percona Server for MongoDB. I know this is feature specific to MongoDB Enterprise. I actually tried enabling this on a secondary node in mongod.conf under “setParameter” but it still shows the initial sync is logical. Thanks! ---

Percona Server for MongoDB doesn’t YET support File Copy-based initial sync. The first version that will support this init sync is 7.0.22-12 - planned to be released July 27 (next week). We’ll follow supporting it in 8.0 as well - about mid-August 2025. We don’t plan to release it for 6.0 and older. ---

> [@radoslaw.szulgo](#): > > 5 Hey that is awesome! Is this expected to increase initial sync efficiency from large databases? Can you also share a brief high level use case for why someone would use File Copy-based initial sync over logical? It would be exceptionally helpful if a File Copy-based configured secondary was able to initially sync from a very large live primary while giving the ability to decrease initial sync time. Thanks! ---

Hope my blog post shares some more light: > **[Scalability for the Large-Scale: File Copy-Based Initial Sync for Percona...](https://www.percona.com/blog/mongodb-fcbis/)** > > Introducing a significant enhancement to Percona Server for MongoDB: File Copy-Based Initial Sync (FCBIS). It is designed to accelerate your large-scale database deployment with a more efficient method for initial data synchronization. Looking forward to your feedback and maybe performance gains you got! ---

> [@radoslaw.szulgo](#): > > [https://www.percona.com/blog/mongodb-fcbis/](https://www.percona.com/blog/mongodb-fcbis/) If I understood it correctly the FCBIS is available only in Pro build. I can’t just use `image: percona/percona-server-mongodb:7.0.22-12` in my CR.yaml and expect it to use FCBIS. Am I right? ---

You’re right. But I have good news to you. Starting from the next release of PSMDB - 7.0.26-14 will contain all features including FCBIS. This will be available within the next two weeks. Observe our release notes page for 7.0 🙂 ---
