Item Subject: Text Item There is also COPYUTIL. It is a utility found on the support media and is run as a stand-alone utility. COPYUTIL is designed to copy data from a given disk to tape and then at a later time, to copy the data back from tape to disk. The utility can be used to save off a bootable copy of the operating systemm and if the system crashes, that version of the boot disk can be restored. Also, you can use COPYUTIL to transfer data from a bad disk to a good disk. <<Most of this text was lifted from an HP training guide>>. A few things about copyutil. - Copies relatively fast, but I suggest not doing a verify using it. The verify does not work too good and takes a long time. It would be wiser to just create 2 COPYUTIL tapes without the verify so you have some protection. - The BACKUP portion of COPYUTIL can tolerate read errors, but will halt on a wite error. The RESTORE command of COPYUTIL will not tolerate read or write errors. I hope this helps.
