    I would like to know, how does the CV's Automatic Scheduling works in the backend

    Suppose if have an automatic schedule set to monitor the archive_log destination every 2 hours and trigger a backup when the usage has crossed 80%.

    What exactly does commvault do in the backend, and how does the oracle agent check the usage of the log destination ?

    If the log_destination usage is 60% if i would wish to know if commvault has done its bi-hourly check where do i get to see these logs.

     

    Thanks in advance!

    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?

    Automatic scheduling is done by sending some schedule XMLs to the client and the client then knows how to do the check and when to start "pushing" data. So the job is initiated from the client (as only the client knows when the Log is full enough for example)...

    I would believe that CVD.log should probably contain some information about this, but I'm not sure... I would need to try this out in my lab to confirm this. So if someone else knows this feel free to add to this discussion :)
