Ghost 14, how to backup partition C ?

When I try to make a backup of partition C, I get the message (Try to translate)
"This task can be done while Windows is active.  You must finish this task in recovery environment, Proceed ? Yes No"

Nothing happens.
When booting from a Symantec Recovery Disk, I can't make a backup, only restore.
