Windows Live OneCare Backup makes a copy of all of your files and folders the first time it runs and once a year during your yearly backup (A full backup of the important files and folders on your computer that starts a new backup collection. The yearly backup is the first backup after the beginning of the year.
) . Normally, backups outside of these times are incremental backups (A backup that copies only those files created or changed since the last full backup.
) . However, there are some other reasons that cause a full backup to be performed:
You are backing up your files to discs and your most recent backup disc is found to be corrupted.
You are backing up your files to an external hard drive and your current backup collection is not found or is corrupted.
You changed your backup device from a disc burner to an external hard drive, or vice versa.
You can also choose to manually perform a new full backup of your files at any time (you might choose to do this, for example, if you have lost one of the discs in your backup collection.)
