Datalake Backup not working

@pandav Welcome to Cloudera Community, I can understand you are facing issues while taking the Data lake backup.

Could you please provide the output of the following command:

# cdp datalake list-datalake-backups --datalake-name dl-name

# df -kha

what is your CDP runtime version, because we have seen this in the past whenever we tried to take Data lake back up, it will backup ranger-HMS-metadata and ranger-audit. The temp file will be written to the master node before moving to S3. The metadata is too big that fills up the root file system on the master node.

You can contact Cloudera support also on this.

Cheers!

I guess the problem is that the root file system master node is filled up. Where cdpcli stores temp file?

No, the cdpcli does not store any file in a temp location. it is the data lake backup that stores the temp file on the master node, you can try the following command:

cdp datalake backup-datalake --datalake-name dl-bakup --backup-name test-backup --skip-ranger-hms-metadata --skip-atlas-metadata
--skip-ranger-audits --backup-location s3a://bucket-name/backup-archive

 Please refer to the below official doc for data lake backup:

Ok, that sounds  good to me, but do you know the path for the temp file? 

thank you! 

@shehbazk I deleted some files and restart backup but got the same problem,

@pandav Thanks for the update, I would request you to please file a support case ticket, We need to check multiple aspects for the backup.

thanks!
