We have observed the following:

  • Operating System: Red Hat Enterprise Linux 9.7

  • MongoDB Version: 8.0.20

  • mongodump Version: 100.16.0

  • Commvault Version: 11.42.90

  • iDataAgent Version: 11.42.90

We are facing an issue where incremental backups fail, while full backups complete successfully. The error indicates that oplog creation failed. However, when we perform the oplog dump manually, it completes successfully.

We also observed that with Commvault/iDataAgent version 11.36.80, both full and incremental backups complete successfully. However, the restore operation fails because the MongoDB service attempts to stop but is not stopped properly by the iDataAgent.
