During a DEC course I recently attended we were informed that /IMAGE must be used otherwise a restore on a brand new disk would not work. The DEC manual (Utilites Reference Manual) does not indicate whether using /IMAGE is essential for a reliable stand alone backup. To add to the confusion... DEC software support in Colorado Springs were positive that the /IMAGE qualifier is implied in stand alone backup and therefore redundant to include in the command line. 2) Does anybody know of a quick way of actually erasing a mag tape? The INITITALIZE command is reversable and sometimes we need to send out a blank tape without the possiblity of its previous contents being read. 3) Does anybody know of a method of changing the modified date of many files across a disk? I once forgot the /RECORD qualifier on a backup and ended up having to do it all over again to get the date right. last question I promise... 4) Using the accounting utility, is there a way of finding the total CPU that was available between the time extremes? I could calculate it by hand using the dates and times supplied or I could write a program to extract the info from a binary version of accountng.dat BUT it would be nice.... We have a 780 running VMS V3.7. Thanks in advance for any help... Peter Stokes Canadian Microelectronics Corporation Queen's University, Kingston Ontario
