Probkup / Prorest Errors On NT When Trying To Access Tape Directly
--------------------------------------------------------------------
SUMMARY:
--------
With version 8.2+ of Progress for Windows NT, it is possible to
backup and restore Progress databases directly to/from a tape
device installed on the workstation / server. Customers may however
receive errors when trying to access this tape device.
Knowledge Base number: 19596
This document applies to : Probkup / Prorest on Windows NT
Version and Release Number: Progress Versions 8.2+
INTRODUCTION:
-------------
These are two reasons why a customer may get errors trying to access
a tape device directly, these reasons are detailed below and are
easily resolved.
STEP BY STEP DETAILS:
---------------------
Probkup <db-name> \\.\tape0
can return the following error messages...
Cannot access backup device \\.\tape0. (3764)
!!! ERROR - Database backup utility FAILED !!! (8563)
prorest <db-name> \\.\tape0
can return the following error messages...
** Cannot find or open file \\.\tape0, errno = 32. (43)
!!! ERROR - Database restore utility FAILED !!! (8564)
One reason why these errors occur is that the device may be in use
(locked) with another piece of backup software, therefore probkup
or prorest is unable to access this tape device.
If the backup software uses a service then this service will need
to be stopped before the probkup or prorest is executed. For
example Arcserve version 6.5 for NT, uses a service for the tape
device, this is "ARCserve Tape Engine". The following could be
incorporated into the backup script:
net stop "ARCserve Tape Engine"
probkup sports2000 \\.\tape0
net start "ARCserve Tape Engine"
Another reason for the above errors, could be that if
the Microsoft NT Backup Utility is open and you attempt
to run the PROBKUP utility, the system returns an error message
when attempting to access the backup device, usually the tape
drive. To use the PROBKUP utility, close the Microsoft NT
Backup Utility first.

NOTE:
====
It is important to note that backing up directly to tape
is only aplicable to versions 8.2+ of Progress. Prior versions
did not have the facility to backup directly to tape, unless
the tape device was able to be mapped as a drive.
