Manual Backups

Savvy users may feel comfortable with manually backing up the Postbox profile.

Since the entire Postbox profile is self-contained, moving it to an external hard drive will accomplish a complete backup. Note: It is not recommended to dissect the Postbox profile to perform a selective backup.
