what is qmgr0.dat and qmgr1.dat?

[AP]

I am using WIN2000 ADV server with backexec 9.0.

Everytime I run the backup it shows failed status with
some exceptions such as;

Unable to open the item c:\documents and settings\all
users\application
data\microsoft\network\downloader\qmgr0.dat - skipped.

it happens on all servers being backup. I believe the
files (qmgr0.dat & qmgr1.dat)are created by the systems.
What are they and why they are unable to open?

Thank you for your attention.

According to the following article, the files are used for BITS. I would
recommend to add them to the Exclusion list for your backup program.

qmgr files are related to BITS service
CCing that newsgroup for more info

Yes, qmgr0.dat and qmgr1.dat are files that are created/used by BITS
(Background Intelligent Transfer service), and they are constantly
in use by the BITS service. One way of avoiding warnings from backup
utilities is to add these files to the "FilesNotToBackup" list
(stored in the registry).

To add the BITS qmgr*.dat files to the list, you could do the
following:

1) Open the Registry key:
HKLM\SYSTEM\CurrentControlSet\Control\BackupRestore\FilesNotToBackup

2) Create a multi-string value with the value name:
BITS

3) Add the following string to it:
%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\*
The BITS 1.5 redistributable packages will add this key as part of
its setup routine, so another way of solving the problem is to
upgrade the BITS version in your system to 1.5.
http://www.microsoft.com/downloads/...C8-2ABF-43C7-AB51-E0C53303086D&displaylang=en

Note that if your system is not a english version of Windows, the
"Application Data" part of the path will need to have a translated
form. Unfortunatelly, BITS 1.5 setup will not automatically detect
this situation, so the correction will be needed in both methods.

A second note is that although Microsoft recommends that backup
utilities utilize the "FilesNotToBackup" key to obtain a list of
files that should be excluded from backup, it is not guaranteed that
all backup utilities will in fact take the list into consideration.
Most of the Backup utilities I know will use the FilesNotToBackup
list, but I don't know if that's true for Backexec 9.0.

Let us know if this info does not help.

[Guest]

I found your explanation of specific backup problem with qmgr0.dat and qmgr1.dat which you solved there. Thank you for it. I would like to inform you, that the same problem is in Windows Server 2003, ENU, Standard. There is BITS 1.5 already instaled, but the right Registry key "FilesNotToBackup" "BITS" is missed. Do you plan to corect this in some path or in SP1
