Backup programs may use some interesting terminology.
Sometimes, the backup manual explains the terms; sometimes, it doesn’t. If not, here are my own handy definitions of various backup terms.
Full backup : This term refers to a complete backup of the entire hard drive. All the files backed up are marked “backed up†by the computer.
That way, you can easily spot new files created after the backup.
Specific backup : Only those files that are selected are backed up.
Incremental backup: This term refers to a backup of only those files created or modified since the last full backup.
Differential backup : This type is the same as an Incremental backup in that only files modified since the last backup are archived. However, unlike an incremental backup, the files backed up are not marked as having been backed up (a rare option to select).
Copy : Files are backed up, but they’re not marked as having been backed up, as they would be for a full backup.
Not only backup for file, the driver require backup to. Windows XP not include the professional backup for their driver. The small utility is usefull for you to backup the driver. Take a look http://tinyurl.com/driver-genius-8-0 is the small utility but more powerfull to backup all your driver.
