Okay, but you are making a backup of data in a database where the
aforementioned index is corrupt, as the system message indicates.

Yes, but you are using +restore-crash-dump against a backup of a
corrupted database. You should have used +crash-dump as per:
./virtuoso -?
Usage:
virtuoso [-fcnCbDARwMKrBd] [+foreground] [+configfile arg]
[+no-checkpoint]
[+checkpoint-only] [+backup-dump] [+crash-dump]
[+crash-dump-data-ini arg] [+restore-crash-dump] [+wait]
[+mode arg] [+dumpkeys arg] [+restore-backup arg]
[+backup-dirs arg] [+debug] [+pwdold arg] [+pwddba arg]
[+pwddav arg]
+foreground run in the foreground
+configfile use alternate configuration file
+no-checkpoint do not checkpoint on startup
+checkpoint-only exit as soon as checkpoint on startup is complete
+backup-dump dump database into the transaction log, then exit
* +crash-dump dump inconsistent database into the
transaction log, then exit*
+crash-dump-data-ini specify the DB ini to use for reading the data
to dump
*+restore-crash-dump restore from a crash-dump*
+wait wait for background initialization to complete
+mode specify mode options for server startup (onbalr)
+dumpkeys specify key id(s) to dump on crash dump
(default : all)
+restore-backup restore from online backup
+backup-dirs default backup directories
+debug Show additional debugging info
+pwdold Old DBA password
+pwddba New DBA password
+pwddav New DAV password
