Exchange 2010 LOG file not purging and growing indefinitely

We moved to Windows System Backups via Ahsay's OBM backup client.  Ever since then I noticed the LOG files keep on growing and growing.  Shouldn't these get purged after the backup?  As I understand Windows System Backup does VSS copy by default.  Waiting for Ahsay to tell me best practice to enable the purging of LOGs...  I guess I would run a different job for that?

Are you doing a Full Backup.  That alone should purge the log files.

You definitely don't want to purge them manually.

I updated the question since initially posting..  We are doing an Ahsay OBM job via Windows System Backup.  Windows System Backup does VSS copy by default.  Waiting for Ahsay to tell me best practice to enable the purging of LOGs via their job...  Based on your response there isn't a way to run a dedicated job just to purge?  The current job does a VSS copy so it won't interfere with other jobs.

Scott C,

I thought VSS jobs done via Windows System Backups only copies them?
CEOs need to know what they should worry about

Nearly every week during the past few years has featured a headline about the latest data breach, malware attack, ransomware demand, or unrecoverable corporate data loss. Those stories are frequently followed by news that the CEOs at those companies were forced to resign.

No, the only correct way to "purge" the log files is with a FULL backup.

Any other way of getting rid of the log files is unsupported and asking for trouble.

I need to create a dedicated Exchange backup that runs FULL once a week and LOG the other days.  Have it finish first and then the VSS copy can run after it, correct?
