Database Backup Failing

I am trying to backup our Database dump. We are using SQL Server as the DB. When I try to back it up, I get the following error message:
Has anyone ever seen this kind of message? Just to confirm, I have plenty of space on my hardrive. IT is about 8GB, and I think DB should be no more than 3-4GB.

TITLE: Microsoft SQL Server Management Studio

Backup failed for Server ‘AMAZONA-4A6HTFA’. (Microsoft.SqlServer.SmoExtended)

Mavinder,

SQL Server thinks that there isn’t enough disk space free. There is not enough space on the disk. It looks like the dump is being written to a temp folder on the C drive which is probably where your TEMP environment variable is set too. Try re-pointing the system TEMP environmental variable to a folder on a drive with more free disk space and restarting the server/services.

Keep in mind that this error might actually be occurring on the remote SQL Server machine itself, not on your local drive.

The problem was because of insufficient space on the disk. Once we added another disk, the problem got resolved, and the backup happened. Thanks
