Hi everyone We recently had a failure of a computer HDD (lost everything, of course) which prompted me to begin exploring backup software and led me to try out Acronis. I acquired an external 300GB eSATA HDD for the backup hardware. I have a demo of Acronis but when I attempt to create a backup it says: "The backup archive file will be created on the dynamic volume. Please note that you will not be able to restore this backup archive when booting from the rescue media. Are you sure you want to continue with this procedure? " Now, after searching the forums it appears that I can convert the dynamic disk to a basic disk to make work for backup. Does the error message mean that if the system were to crash, I could not restore from a backup file created on this dynamic disk? Thanks for any replies, sorry if I missed an obvious answer somewhere - just post a link to it.
