When I run pbm backup, the full backup is not created. I need everyone’s help with this issue.

Hi @Linh_T_Khanh,
Welcome to the community!
Regarding the error
```auto
2024-01-14T12:55:08Z I [rs-db/mongod:27017] [backup/2024-01-13T04:26:26Z] mark backup as error check cluster for dump done: convergeCluster: get backup metadata: not found:
```
please share the pbm logs along with pbm status, from below command:
```auto
pbm logs -e backup/2024-01-13T04:26:26Z -s D -t 0
pbm status
```
Also, can you confirm if you have scheduled the pbm backup via cron and cleanup is also included after it?
Thanks,
Mukesh

I have just sent more details.
Yes, I have scheduled the pbm backup via cron and cleanup. Backup storage is always sufficient enough for next full backups.

Hi @Linh_T_Khanh
I believe, you have scheduled the pbm backup and cleanup simultaneously. The cleanup command was designed to work not during backup.
Can you please share the cronjob of backup and cleanup?
Also, we could see pbm version is of 2.1 and we recommend upgrading it to the latest version i.e. [pbm 2.3](https://docs.percona.com/percona-backup-mongodb/install/repos.html).
Thanks,
Mukesh

The error mentions waiting for the oplog. Ensure that the MongoDB oplog is accessible and that there are no issues with its size or configuration. The oplog is crucial for maintaining the consistency of the backup. Use MongoDB diagnostic commands, such as `rs.status()` and `db.currentOp()`, to gather more information about the state of your replica set.
