Ive heard of full, differential, and incremental backups and media rotation. Do I need to understand these terms to use LifeLineDVD?
The evolution of various combinations of full, differential, and incremental backup strategies are a direct consequence of having to reuse expensive tape media. You don’t want to back up too much too often, or you will use too many tapes. But backing up too little or too seldom risks data loss, and can make restoring data a laborious process. With tape backup products some tapes need to be rotated offsite on a daily or weekly basis, while others need to be brought onsite and reused. After a certain number of uses, the tape must be retired. Newer backup methods that use external hard drives or Internet-based storage have similar problems. In contrast, LifeLine DVD has one simple backup rule: scan the network if a file is new or has changed, back it up. The first time LifeLine DVD scans a computer everything will be new to it, so it all gets backed up. On subsequent scans, every changed or new file will be backed up.
