Both separate file store (used by MDaemon) and DB file store (Used by others) have their pros and cons.

I am using Archive Server for MDaemon, which is using third way of saving Email files.

It manages Emails like Drive:\Year Folder\Month folder\date database file. The index of this date database is maintained in SQL server. This have pros of both file store and DB store, while quick to backup and more secure as the emails stored in individual files are readable using notepad.

I have used few backup solutions and all of them are slow when it comes to backup small kb files in large number.

Can MDaemon email store be managed this way?
