Because your TntMPD database is "mission critical", literally, critical to your mission, TntMPD performs automatic backups of your database when you:
•Exit TntMPD (unless you turned that option off in the Options)
•Log Group History

•Upgrade from a previous version 1.6 to 2.0 or 2.0 to 2.1, etc.
•Import contacts from a text file
Defining Backup Location
TntMPD will choose a backup location automatically, or you can specify the automatic backup location in your installation options. Once you set a location, that location will carry over even to future upgrades.

Manual Backups
Although TntMPD performs auto-backups as described above, you can manually backup your file.

Restoring a Backup
You can restore either a manual or auto-backup. TntMPD will browse to your backup folder and show you all of your recent backups, both manual and automatic.

External Backups
Although TntMPD automatically backs up your database, it only backs up to your hard drive (by default). If your database is also on your hard drive, then your data is only as secure as your hard drive, either from crashing, theft, or act of God (e.g., fire). You should regularly back up your TntMPD database to an external location, such as a CD/DVD or a flash drive, so that you have a separate copy of your database.
