I would like to use IDS 11 ontape to directory devices with the new
BACKUP_FILTER parameter in $ONCONFIG set to "gzip". Everything works fine
except for archecker, which would be a big problem if you needed to restore
individual tables. It is displaying but failing to apply the documented
AC_RESTORE_FILTER parameter in $AC_CONFIG: with or without this set, it
reads unfiltered backups OK but fails to read filtered backups, irrespective
of the device type (file or directory). Has anyone else encountered this? I
have produced the same results with:

IDS 11.10.TC1 on Vista
IDS 11.10.FC2 on SLES 10

See "ac_msg.log" output below with debugging enabled.

Regards,
Doug Lawry
