About two processes trying to use the same drive
Careful configuration of your environment can help avoid resource contention during Vault duplication. Resource contention can occur when two processes try to use the same drive at the same time.
To avoid resource contention, use one of the following alternatives:
Alternative A: dedicated robot for Vault processing
Alternative B: each robot as a Vault robot
Alternative C: one robot as both a backup and Vault robot
See Alternative C: one robot as both a backup and Vault robot.
These alternative configurations work well for multi-robot environments. They use available resources efficiently and are unlikely to cause resource allocation problems.
Note:
If you vault original backups, you do not have to use practices that avoid or reduce Vault resource contention.
