Can I backup up an entire, working operating system and, in the case of a failure, restore it on another drive?
Yes, Ferro Backup System supports backups of working operating systems and it is also possible to restore your operating system without the need to reinstall it (bare metal restore). This works in the same way as drive/partition image software (e.g. Norton Ghost, Acronis True Image). For details see: Operating system backup and Operating system restore.
