Backup for Azure Data Lake fails when a back-level media server is used with backup host or storage server version 10.3
Error message
bpbkar Exit: INF - EXIT STATUS 3600: Cannot perform the COSP operation.
Error nbpem (pid=13052) backup of client azuredatalake_COSv17_adlsgen2xxxxx.xxxxxxx exited with status 3600 (cannot perform the COSP operation).
Explanation
Support for Azure Data Lake was introduced in NetBackup version 10.3, so this workload does not work on media or storage server versions before 10.3.
Workaround
Ensure that media server, backup host or scale-out server, and storage server versions are 10.3 or later.
