Restoring From Backup...

MacInvoice creates two database files in your Preferences folder. One is named MacInvoice Database.rdb. The other is the automatic backup file named MacInvoice Database Backup.rdb.

If for some reason your main database becomes corrupted, you can restore it from either the backup database or from disk. Simply name the backup file the same as the original MacInvoice Database.rdb, then restart MacInvoice.
