hey guys,
I was searching on net regarding the transaction log failure error,
I am getting the error

"Downgrading backup buffers from 960K to 64K"
While reading documentation on MSDN They asked to install hotfix,But I have already SP4 an latest hotfix build 2187 installed three weeks back to fix the same issue.
Now,I was just trying to find out the buffer count and
The value of the BufferCount parameter is calculated by using the following formula:
NumberofBackupDevices*3 + NumberofBackupDevices + NumberofDatabaseFiles = BufferCount


How to find
Number of Backup Devices
Number of Databasefiles.

Please help to fix this issue,Just calculating the buffer count,I will not be able the to fix the issue.
Your help is required.

You can find number of db files by querying sysfiles1 table in the db. Number of backup devices is device you specified in backup statement.
