Rejean,

interesting command, but ... are you sure?

This command seems to list all inactive backup copies (where ever they are)
of a file having one backup copy on the chewed cartridge. So, if "file_a"
has one active and four inactive backup copies and one of these copies is
on the chewed volumes, the four inactive copies will be listed, right?
And I still do not know, whether the affected copy is the active one or
one of the inactive ones, right?

Again, an unique connection between the CONTENTS table and the BACKUPS
table is missing. Without this connection, an entry in the CONTENTS table
does not tell me, which of the possibly many backup or archive copies of
a file it refers to. It seems to me, that the OBJECT_ID field should be
included in the CONTENTS table.
