6.1 Copying modes
ery sec-tor. Different sizes of the hard disks result in a non-copied resp. non-overwritten area
(6.2 Size differences).
The drive-to-drive copying mode is especially useful for the following areas of use:
• Migration of an existing operation system installation to a larger drive (2.1 Upgrading hard
disks & migrating an OS).
• Rescue of entire hard disks (2.2 Data rescue).
• Backup and restore of entire drives or operating system installations (2.3 Installation back-
up).
• Multiple installations (2.5.1 Duplicating system installations).
• Copying proprietary file systems and data formats onto another drive (2.6 Proprietary hard
disk formats).
• Backup of hard disk data for a forensic evaluation and further processing (2.7 Forensic data
securing).
6.1.4 Partition-to-partition
This copying mode functions similarly to the
above described mode (6.1.3 Drive-to-drive).
However, in this case, not the whole hard disk is
copied, but only the content of an individual parfig. 19: Partition-to-partition
tition is copied. This copy is executed sector by
sector, too. Relatively a the beginning of the respective partition, the individual sectors are also
moved to the same address. However, due to the principle and in contrast to the drive-todrive mode, the individual sectors are not at the same absolute address in relation to the complete hard disk. Perhaps such a copy is therefore not directly usable, but only after it has been
copied back (2.3 Installation backup) or adapted to the changed absolute position on the
hard disk (5.10.3 Adjust media parameters).
The partition-to-partition copying mode is especially useful for the following areas of use:
• Migration of an existing operation system partition to another drive (2.1 Upgrading hard
disks & migrating an OS).
• Rescue of individual partitions (2.2 Data rescue).
• Backup and restore of individual (operating system) partitions (2.3 Installation backup).
• Multiple installations of individual (system) partitions (2.5.1 Duplicating system installations).
• Copying of proprietary file systems and data formats onto another drive (2.6 Proprietary
hard disk formats) - only with a valid partition table!
• Backup of individual partitions for forensic analysis and further processing (2.7 Forensic
data securing).
• Temporary storage or intermediate storage of a partition, e.g. in case of a reorganization of a
hard disk.
• Relocating a partition within a medium or to another medium.
