Well, i can give you my opinion on a couple of aspects of Informix
back-up/recovery functionality. It may be that I have missed something,
so I'm pleased to stand corrected:
1. (I have a lot of trouble explaining this point to Informix pros.) I
don't really understand why OnLine insists that you have the original
paths available for a restore. It should be possible to do a restore as
follows; if the chunk(s) for the rootdbs, or any chunk for any other
dbspace, is unavailable then the user should be prompted for the name of
a valid alternative chunk location.
2. Doing a "strings" on an archive will allow you to pull off the
$ONCONFIG settings applicable at the time of the archive. But so far as
I am aware, the timestamp of the archive is not available. This could
be very useful.
3. ontape should permit the user to specify an alternate location to
$TAPEDEV for the location of the archive (for those of us who archive to
disk).
