Table 1-1. Cloning Modes
Data Copy Types Application Description
Volume based Copy volumes from the source
machine to the destination machine.
Volume-based cloning is relatively
slow. File-level cloning is slower than
block-level cloning. Dynamic disks are
converted into basic volumes on the
target virtual machine.
Disk based Create copies of the source machines,
for all types of basic and dynamic
disks.
You cannot select which data to copy.
Disk-based cloning is faster than
volume-based cloning.
Linked clone Use to quickly check compatibility of
non-VMware images
For certain third-party sources, the
linked clone is corrupted if you power
on the source machine after the
conversion. Linked cloning is the fastest
(but incomplete) cloning mode that
Converter Standalone supports.
Volume-Based Cloning
During volume-based cloning, volumes from the source machine are copied to the destination machine.
Converter Standalone supports volume-based cloning for hot cloning, and during the import of existing virtual
machines.
During volume-based cloning, all volumes in the destination virtual machine are converted to basic volumes,
regardless of their type in the corresponding source volume.
Volume-based cloning is performed at the file level or block level, depending on the destination volume size
that you select.
Volume-based cloning at
the file level
Performed when you select a size smaller than the original volume for NTFS
volumes or you choose to resize a FAT volume.
For FAT, FAT32, NTFS, ext2, ext3, ext4, and ReiserFS file systems,
Converter Standalone preserves the file system type during a volume-based
cloning at the file level.
Dynamic source disks are read but not preserved during volume-based
conversions. Dynamic disks are converted into basic volumes on the target
virtual machine.
Volume-based cloning at
the block level
Performed when you choose to preserve the size of the source volume or when
you specify a larger volume size for NTFS source volumes.
Disk-Based Cloning
Converter Standalone supports disk-based cloning to import existing virtual machines.
Disk-based cloning transfers all sectors from all disks and preserves all volume metadata. The destination
virtual machine receives partitions of the same type, size, and structure, as the partitions of the source virtual
machine. All volumes on the source machine's partitions are copied as they are.
Disk-based cloning supports all types of basic and dynamic disks.
Full and Linked Clones
Clones can be full or linked depending on the amount of data copied from the source to the destination machine.
A full clone is an independent copy of a virtual machine that shares nothing with the parent virtual machine
after the cloning operation. Ongoing operation of a full clone is separate from the parent virtual machine.
