I reformatted the terabyte drive using a Windows 7 quick format tool in Windows 7. Now I need to back-up my hard drive with the EaseUS back-up sware. My choices in the Easeus sware are:

- system clone - I tried this but got an error message saying I can't back-up MBR drive to a GPT drive
- clone - I lean towards this approach for initial back-up
- system back-up

Second question is how I approach a subsequent back-ups after the initial back-up
___________

I would choose clone. Second option. Ghost has the ability to do incremental backups after the initial backup is complete. The first one will be a full backup and all backups that follow will only contain additional information. A common mistake that users make is to delete partial information off of their backup drives to free up space later. It's best to trust the software to do its job and leave the drive alone. Additionally, never store other data on the backup drive. The backup drive is simply a copy of your internal drive and not a storage drive for any other information.
