Synopsis
asr -sourcesourcepath
-targettargetpath
[options
] asr -imagescanimagepath
Accurately 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.
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.
