Now that you understand about backup procedures, you are ready to begin using The Vault. Boot your machine normally, and be sure always to set the clock. Incremental backups will not work properly unless the clock is always set correctly whenever you are using the machine, for otherwise the file dates will not be meaningful.
Copy the files VAULT.PRG, VAULT.RSC, and VAULT.HLP to your hard disk program folder. Put your Vault distribution disk in a safe place and double-click on VAULT.PRG. You are now standing in The Vault, the most sophisticated backup program that exists for the Atari ST.
