Run backup and it starts, backs up the services page, the CDR database, the DCD database,the TFTP files dumps them all to the staging area. Then it starts building the archive file at the designated location. It gets one or 2 percent done then errors out, saying that the destination archive is smaller than the staging size. the staging directory is 299 MB and the archive location has 32 gigs of free space. Why does this happen and how do I fix it?

Hi Dave,


Maybe you are hitting this bug;


CSCee43938 Bug Details


Archive file size is less than staging directory


Symptoms:

BARS incorrectly reports file size limits when doing backup making it fail


Conditions:

BARS version 4.0(4) and earlier


Workaround:

First of all verify that the location where the archive is being created has

enough space, i.e. more than the staging directory size as indicated in the

BARS log. In that case, this is a valid message indicating that storage

destination location doesn't have enough space to host the archive file.


If there is enough space, and the message is still displayed, it could be

because of the following:

The problem occurs only when a single file has a size more than 2 GB. This

usually is the CDR database.

Purging old CDR records or deselecting CDR database backup during BARS

configuration can avoid this situation.





Update on 05/28/2004:-


The problem arose because the database size has increased more than 2GB and

BARS is unable to create the archive properly when a single file size is more

than 2 GB. Try to delete the records of the database which are not required and

then do a Backup.



Or this from Tray;


OR it can be a problem with NIC card settings on the destination file server.


Event ID: 50

Event Type: Warning

Event Source: Ftdisk

Description: {Lost Delayed-Write Data} The system was attempting to transfer file data

from buffers to \Device\LanmanRedirector. The write operation failed, and only some of the

data may have been written to the file.

Checked the Link Duplex / Speed on the server to which they were backing up to and it was

set to " Auto Detect ". Changed it to Full / 100 and now the backups work fine.



Hope this helps!

Rob

Hello, and thanks for the help, however while you appear to be describing what is happening, I am running BARS version 4.0.14 and cant seem to find a later version on the site. There does not appear to be a way to select which parts to back up and the staging directory size is only 299 megs so it should not be the 2 gig problem. Any other ideas?

Have you tried changing the destination drive or checking the permissions of the TFTP directory?

I did change the destination for a test but that did not make a difference, as for the TFTP permissions, they should be alright since it successfully stages it, correct?

The TFTP permissions should be correct then. Anything in the application event viewer to give you any clues or restarting the BARS scheduler?
