OSB File system backup fails with 'Error: NDMP operation failed: data service reported connect error' (Doc ID 1544050.1)

Last updated on APRIL 03, 2020

Applies to:

Oracle Secure Backup - Version and later
Linux x86-64


Different file systems backups, from different clients, fail with the following error in the transcript:

Dumping all files in /usr
Error: NDMP operation failed: data service reported connect error
Error: bytes moved reported by data service and mover differ
Error: data Service reported 0x9ADD0000; Mover reported 0x9ABC0000


If the dataset has multiple file systems, some file system backups may complete successfully, and only one file system backup will fail, causing the subsequent file system backups not to start:

A stop/start of the OSB daemons on the admin server and affected clients did not change the behavior.


No changes were made to either the admin server or any of the clients.
