I could not find any Microsoft documentation for the following scenario:

Scheduled backup job fails (let's say because the VM being backed up was shutdown). As per my understanding MABS should retry to backup without waiting for the next scheduled time.

Ask:
Need a document that says MABS retries to backup when a backup job fails. Also, need to know the time it takes to retry again and how many retries before it gives up.

This kind of information should be there in documentation and I would be happy if it can be made available soon. If it's already there then please do send the link.
