Usually there is no [000000]GPT.SYS on an Alpha system disk. So a
BACKUP/IMAGE restore should not restore that file. Restore also
shouldn't create one. As far as I understand this file is created at
init time. Which leads to the question, which actual commands were used
to restore the image backup? Also the command to create the backup may
be of interest. It is in the backup save set (if a save set was used at
all). A BACKUP/LIST will show it in the summary section (or the bcksum
utility will print just that summary). It also contains the backup
version as well as the VMS version.

If you want to see what is on the restored disk, which you can't mount
as an ODS disk, you should mount it /FOREIGN and dump the first two
blocks. There are strings which identify the I64 (system) disks and the
EFI/GPT.
