How do I create a backup of a vhd file?

Question

How to back up a vhd automatically? Is there any tool which I can set up?

Solution

If you have a usb storage you can just windows server backup or windows backup and restore if you are on windows 7 ;

Windows Server Backup, backsup in vhd format too - so you can either restore the whole box or you can mount your backup drive, take ownership of the backup folder, browse to the directory and attach the vhd as a readonly option in Windows 7 and Windows 2008 R2, then browse the contents of your vhd file, so if you had some vms running on this server, you can extract those vhd's too.

there are other tools available which may allow you to mount vhd's in xp / vista too but windows 7 have it native.

You can schedule a windows server backup to backup whole server and that should do the trick,.
