Trying to recover from disk based backup, results in the following error message "could not stat disklist:/backupdir/slot02"

One of the reasons why this error could occur, is due to the fact of not use the "FILE" directive properly. When you recover from a disk based backup using amrecover, you will have to use the "FILE" directive when doing a settape. For example

amrecover> settape file:/backupdir/slot02

If you are reovering from a remote system then the usage is

amrecover> settape myhost.mynetwork.com:file:/backup/slot02
