what will be size of backup file(FULL) for 1TB database. Just wanna make sure backup is done right.I did a full backup of 1TB database and backup file came like 507GB. I am using GUI for backup.But it completed 100% but didn't give me the screen'The backup is completed successfully' .it says executing---0%

It'll be about the same size as the filled portion of the MDF file.

So Tara why didn't i get 'The backup completed successfully' in GUI.Do you think 507GB is good for 1TB database size.

Try using BACKUP DATABASE command instead just in case.

BACKUP DATABASE YourDbName
TO DISK = 'F:\Backup\YourDbName.BAK'
WITH INIT

I have no idea if 507GB is the right size of the backup file. If it is, then your database is smaller than you think. You are probably saying 1TB due to the size of the MDF file.

How much space used? Backup file size is similar to used space size.
