Monitoring and troubleshooting backup jobs

Backup streams in a multi-host environment can be identified by looking at the job details section of the parent backup-from-snapshot job. The example snippet mentions child jobs (streams) started on multiple backup hosts.

Jan 23, 2024 11:36:12 AM - Info nbjm (pid=6493) Started child jobs 563, 564, 565, 566, 567, 568, 569, 570, 571, 572 on host host1.domain.com 

Jan 23, 2024 11:36:12 AM - Info nbjm (pid=6493) Started child jobs 573, 574, 575, 576, 577, 578, 579, 580, 581, 582 on host host2.domain.com 

" 

If there is a failure in resource allocation to any stream, the entire backup job for that volume fails and the parent job fails with error code 927. If you have selected the backup host pool as All media server, then the error 930 is shown.

You can resolve the majority of the problems for multi-host backups by checking the logs. For more details about troubleshooting, see:
