I need a solution
Do anyone know what is OS media?
In my environemnt, BE server create backup job to backup VM to deduplicaton storage.
Open Backup Exec button -> Configuration and Setting -> Audit Log
I found several message about "OSTXXXXXXX has been overwritted" happened when backup job was started to run. Please refer to attachement
What is "OSTxxxxx" ?
A lot of message about "disk lifecycle management (backup set retention)" were found in audit log as well.
Do these messages means deduplication reclamation (free up disk space) happen at this time?
