Issue
Unable to run log file backup on “Public Folder Database”. Please disable circular logging or run database backup instead.
This is expected with Exchange server \ mailstore backups because log rotation creates a lot of logs which slows down backup and restore times.
Turning off circular logging allows the BOBcloud software to manage the transaction logs more efficiently.
