Issue:

Vertica Backup utility vbr.py exits with error.

[xxxxx@xxxxxx ~]$ /opt/vertica/bin/vbr.py --task backup --config-file [name_of_config_fil].conf

Error: Unable to launch rsync daemon on backup host: xxxxxx-vm. 

Backup FAILED. 

 

Environment:
CA Performance Management 2.8 and 3.0
Cause:

Run ps -ef  and check if the rsync daemon is in fact running on the host which is reported on the error.If it is running that is the cause of the error. There seems to be a some communication error between Vertica and rsync.

Resolution:

kill the rsync daemon manually with pkill, and then re-initialise Vertica's backup configuration with

/opt/vertica/bin/vbr.py --config-file [name_of_config_fil].conf --task init

Start the backup 

/opt/vertica/bin/vbr.py --task backup --config-file /Path of the file xxxxxxx.ini
