We had a similar issue when backing up over a network. This is caused by the network configuration and has nothing to do with SQL Server itself. You can reproduce the issue by trying to copy a +50GB file from/to the network location outside of SQL.

[font="Verdana"]When you try to take the backup of 50GB db on network share the time taken will be high and if a network glitch happens then the backup will get stopped. Hence its better to take the backup in local drive and copy it to the network drive using robocopy. This way you can easily copy it.[/font]

Hi,
Thank you for all positive feedback.
I will consider all your comments and suggestions.
But, is it a bug or something on SQL Server 2005?
Thanks

It's not a bug in SQL Server. It's a network issue.

We backup our db of size 60Gb directly to a remote network drive, it takes time compare to the local drive, create a maintainace plan of your backup and i hope it will work for you.

This might be a network issue.
Thanks for your help.

It may be the IRPStackSize bug. You can google it, but essentially you need to alter/set a registry setting. The max value is 50, but I'm finding that even with that we are hitting the wall with our 45+ gig backups. For this reason we are switching to Redgate SQL backup. Here's my solution notes below that I cribbed from some web source:
These error messages can indicate the IRPStackSize bug on the other machine (the server that has the share). On that computer open the event log and check for event ID 2011. If this is present, it is a strong indication for this particular bug.
To repair it, you have to reset the IRPStackSize parameter back to its default value of 15 on the server where the share is.
HKEY_LOCAL_MACHINE
\SYSTEM
\CurrentControlSet
\Services
\lanmanserver
\parameters
Check for the presence of a value named IRPStackSize. If it doesn't exist, create it as type DWORD. With base set to decimal, enter the value 15.
Reboot the computer.
If a job fails because of this, you get nothing helpful for an error message. But if you directly try dragging the 'monguous file from A to B, you'll get an error message near the end about "server space".

There is a free product by Idera called 'SQLsafe Freeware Edition' that allows compressed backups over the network. You can download it from http://www.idera.com/Products/SQLsafefree/Default.aspx
Maybe worth a look...
