1. For scheduled daily backup, the backup destination (60GB hard disk) has twice capacity as the source partition (30GB size, usually 20GB used). What's a good way to set up a backup job, maybe with new features in version 10? (Not in secure zone) Currently I have Backup Location with size limit at 45GB and incremental backup. I don't know if this works. 2. For scheduled monthly partition backup to a different location, I would like to keep a full backup that never changes, and differential backups of 1 to 3 months depending on space. How to do this? (Not in secure zone) 3. Are the images created by version 10 readable by version 8 and 9?
