Start backup when disk at log destination is
Runs the job when the log files on the disk use this percentage of the storage space. The default is 80 percent.
For SQL Agent, starts the backup operation for log files only if 80 percent of the space available within the log file (per maximum log file size) is full.
Note: Automatic schedule does not work for an SQL Availability Group client.
Regarding the log files to check this, I am not sure which to check.
If someone from Commvault support reads this, can you confirm where to look?
