Copying large volumes

[DisMyMac]

SuperDuper and TimeMachine both have great features, but do they offer any advantage over Finder for copying large volumes only once? For example, do they optimize files, defragment, or alert you to data corruption any better than drag-and-drop copying between disks?

For simply transferring files, drag and drop works fine. The other apps don't optimize, defrag or analyze files for corruption. They simply create backups, so if a corrupt file is backed up, the backup copy will also be corrupt. This is true when using Finder, as well. If you want to schedule regular backups or incremental backups or create a bootable backup of your internal drive, I recommend Carbon Copy Cloner.
