 [==================================================] 100%/opt/vertica/bin/vbr.py:6690: DeprecationWarning: datetime.datetime.utcnow() is deprecated and scheduled for removal in a future version. Use timezone-aware objects to represent datetimes in UTC: datetime.datetime.now(datetime.UTC). 

Environment

• Product: DX NetOps Performance Management (Data Repository)
• Database: Vertica
• Utility: /opt/vertica/bin/vbr.py
• Task: copycluster

Cause

The vbr.py script and its underlying code are maintained by Vertica.

These DeprecationWarning messages are non-fatal and do not impact the functional success of the backup, restore, or copycluster operations.

Resolution

Vertica is aware of the deprecation and will remove the deprecated commands in a future build of the software.

 

Customers can safely ignore these warnings in the current version as the operations remain functionally intact.
