Backup to a network PC-need help!

I have just used True Image for the second time. The first time I backed up my E partition which contains all my own data to my F partition on the same disk
It worked a treat.
I then thought that instead of backing up to a partition on the same disk I would like to try backing up to my other PC which is on my network.
I carried ot the same backup of E partition changing the title, hoping that I could choose a different location, but the backup proceeded to backup to my F partition. So I ended up with two similar backups on F partition.
Why did it not give me the option of backingup to a different location?

I have now discovered that I was making a mistake in selecting where the backup was to be located.
I still cannot backup to my other PC on the network
Any ideas

I have now found that I can copy the backup file I created to my other PC on the network. That appears to be a satisfactory situation
