Like the OP, I also used dd to clone my boot drive. Worked great. Although the effort and knowledge is appreciated, can anyone answer the original question or not? Is it possible to mount the cloned drive when also booting off the drive that was the source (was cloned)?
If impossible, then I suppose the only way to use dd for ongoing backups is to make a full backup every time. I thought other people used dd in combination with incrementals, but apparently not (unless the above question can be answered in affirmative)?

mount_pcfs
mount_pcfs(1M) System Administration Commands mount_pcfs(1M)
NAME
mount_pcfs - mount pcfs file systems
SYNOPSIS
mount -F pcfs [generic_options] [-o FSType-specific_options] special | mount_point
mount -F pcfs [generic_options] [-o FSType-specific_options] special mount_point
DESCRIPTION
mount attaches an MS-DOS file system (pcfs) to the file system hierarchy at the mount_point, which is the pathname of a directory. If
mount_point has any contents prior to the mount operation, these are hidden until the file system is unmounted.
If mount is invoked with special or mount_point as the only arguments, mount will search /etc/vfstab to fill in the missing arguments,
including the FSType-specific_options; see mount(1M) for more details.
The special argument can be one of two special device file types:
o A floppy disk, such as /dev/diskette0 or /dev/diskette1.
o A DOS logical drive on a hard disk expressed as device-name:logical-drive , where device-name specifies the special block device-file
for the whole disk and logical-drive is either a drive letter (c through z) or a drive number (1 through 24). Examples are
/dev/dsk/c0t0d0p0:c and /dev/dsk/c0t0d0p0:1.
The special device file type must have a formatted MS-DOS file system with either a 12-bit, 16-bit, or 32-bit File Allocation Table.
OPTIONS
generic_options
See mount(1M) for the list of supported options.
-o
Specify pcfs file system specific options. The following options are supported:
foldcase|nofoldcase
Force uppercase characters in filenames to lowercase when reading them from the filesystem. This is for compatibility with the pre-
vious behavior of pcfs. The default is nofoldcase.
FILES
/etc/mnttab table of mounted file systems
/etc/vfstab list of default parameters for each file system
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
+-----------------------------+-----------------------------+
|Availability |SUNWesu |

SEE ALSO

NOTES
If the directory on which a file system is to be mounted is a symbolic link, the file system is mounted on the directory to which the sym-
bolic link refers, rather than on top of the symbolic link itself.
