Parameters
in-spec
You can type up to six input file specifications. If you specify a saveset or logical-
disk subset, then it must be the first input specification and cannot contain
wildcards. Otherwise, you can use wildcards.
You can specify only one input device; that is, all the input files must be on the
same device. DK is the default input device.
The ssname file name means saveset name, and the ldname file name means
logical-disk name. Both of these names can be from one to six alphanumeric
characters long with a file type of up three alphanumeric characters.
Saveset
A saveset is a special file created by the BUP utility to hold one or more files
or an RT–11 volume or device image you specified with the BACKUP command
