Disk Copy Utility — To make an image of
a disk after install or upgrade (HP-UX 10.x
to 11.x)
COPYUTIL is designed to copy data from a given disk to a tape and then at a later time,
copy the data from the tape back to a disk. The utility can be used to save off a bootable
copy of the operating system and if the system crashes, that version of the boot disk can be
restored. Lastly,
COPYUTIL can be used to transfer data from a bad disk to a new good
disk.
NOTE For systems going from HP-UX 10.x to HP-UX 11.x, CopyUtil can be used to
make a system disk image so that the system can be dropped back to 10.x if
for some reason 11.x is not desired.
The utility uses two commands, BACKUP and RESTORE , to perform the copying of
information between devices. Both commands in effect perform the same function, copying.
However the
BACKUP command copies data from disk to tape and can tolerate read errors
but will halt on a write error. The RESTORE command, on the other hand, copies data from
tape back to disk and will not tolerate read errors, or write errors.
COPYUTIL supports all bootable disks on all HPPA supported systems. Thus, all SCSI2
hard drives and Disk Arrays are supported. CD-ROM drives and MO drives are not
supported.
CAUTION CopyUtil is designed to recover data off of defective disks. It is NOT intended
to be a system-level backup tool.
