I have NTI Backup Now EZ that came bundled with a Toshiba 320GB external hard drive. I have it scheduled to back up daily. If I get rid of a bunch of stuff from my computer hard drive will the next backup automatically delete those files from the Toshiba as well? I actually would like it to. In other words, would I see a corresponding reduction in used space on the Toshiba because I deleted files from the main hard drive?

It shouldn't delete files in the backup when they are deleted from the main drive. When you think about it, to do so would defeat the object of a backup as you most need it when files have been deleted. There is no way of the backup system knowing whether the files have been deleted accidentally or deliberately.

What you need to do is to configure the backup software to do a complete backup daily then delete old backup files when they are no longer needed.

Read the instructions very carefully. There are many different backup schemes from incremental, differential and daily, all, behaving slightly differently. You need to chose the one that suits you.

Thank you! Helpful information. This software gives me the options of backing up files and/or the complete system. Are these mutually exclusive things, or am I being redundant if I select both files and complete system?

You can either backup individual files or the complete system, one or the other. I wouldn't bother as most of the system files can be restored by the operating system if you need to do a reinstall.

Backing up the entire system on a daily basis is just a waste of time and space. Once a month should be enough.

The best plan is to do an incremental backup once a day where only files that have changed are backed up then a complete backup once a month, then start a new incremental file archiving the old on on CD/DVD.

There should be a scheduler to do different types of backups and daily, weekly and monthly basis.

You could adopt the Grandfather, Father, Son principle of backup rotation. This ensures that you have a full backup to fall back on if anything goes wrong as backups of the latest changes as well.
