Synopsis
asr -sourcesourcepath
-targettargetpath
[options
] asr -imagescanimagepath
Copies the contents of a disk image or source volume onto a target
volume. asr
(Apple Software Restore) can also scan
and prepare disk images when given the -imagescan
option, allowing the images to be restored from more efficiently.
asr
usually needs to run as root.
sourcepath
can be the pathname of either a
disk image or a volume, while targetpath
can specify only a volume. Volumes can be specified by either their
/dev
entries (e.g.,
/dev/disk0s10
) or mountpoints (e.g.,
/Volumes/Disk 2
).
For disk image
creation, use either Disk Copy or the command line utility
hdiutil
. Once a volume has been restored, it might
be necessary to use the bless utility to make it bootable. (See
hdiutil
and bless
).
For a complete description of the imaging and restoration process, as
well as tips on optimizing restores using the buffer settings, see
the asr
manpage.

can’t be block-copied; an error will occur.-
-buffersize
n
During block-copies, use buffers of size
n
bytes instead of the default 1000.n
can also be specified in bytes, kilobytes, megabytes, or gigabytes by appending it withb
