A linked clone is a copy of a virtual machine that shares virtual disks with the parent virtual machine in an
ongoing manner. A linked clone is a fast way to convert and run a new virtual machine. You can create a linked
clone from the current state, or snapshot, of a powered-off virtual machine. This practice conserves disk space
and allows multiple virtual machines to use the same software installation.
All files available on the source machine at the moment of the snapshot continue to remain available to the
linked clone. Ongoing changes to the virtual disk of the parent do not affect the linked clone, and changes to
the disk of the linked clone do not affect the source machine. If you make changes to a source Virtual PC and
Virtual Server machines, or to LiveState images, the linked clone is corrupted and you cannot use it anymore.
A linked clone must have access to the source. Without access to the source, you cannot use a linked clone at
all.
For more information on how to create a linked clone, see “Create a Linked Clone,” on page 58.
Destination Disk Types
Depending on the destination you select, several destination disk types are available.
For detailed information on destination virtual disks types, see Table 1-4.
Table 1-4. Destination Disk Types
Destination Available Disk Types
VMware Infrastructure virtual machine
Thick
Copies the entire source disk size to the
destination, regardless of its used and
free space.
Thin
For managed destinations that support
thin provisioning through GUI, creates
an expanding disk on the destination.
For example, if the source disk size is
10GB, but only 3GB is used, the created
destination disk is 3GB but can expand
to 10GB.
VMware Workstation or other VMware virtual machine
Pre-
allocated
Copies the entire source disk size to the
destination, regardless of its used and
free space.
Not pre-
allocated
Creates an expanding disk on the
destination. For example, if the source
disk size is 20GB, but only 5GB is used,
the created destination disk is 5GB but
can expand to 20GB. Take this expansion
into account when you calculate the free
disk space on the destination datastore.
2GB Split
pre-
allocated
Splits the source disk into 2GB sections
on the destination.
2GB Split not
pre-
allocated
Creates 2GB sections on the destination
that include only the real used space on
the source disk. As the destination disk
grows, new 2GB sections are created to
accommodate the new data until the size
reaches that of the original source disk.
To support destination virtual disks on FAT file systems, divide the source data into 2GB files.
