I didn't make my point clearly enough: I've not had any problems with
doing restores per se, but doing a restore results in the onarchive
catalog, which is just a table or group of tables I guess, in a state
prior to its knowing about the archive from which you've just restored.
This results in an inconsistency message, requiring a proceed/cancel
reply next time you launch an archive, which is easy enough to bypass
interactively, but fatal if your archives are scripted.

Exactly what I do. And always have done with tbtape/ontape.
As to an alternative to onarchive; my site is quite new to Informix, and
before I arrived was being administered by Informix consultants. They
had installed the onarchive procedures because we had a requirement to
back up to disk (the archive is immediately ftp'd to a remote site for
contingency), and ontape to disk isn't supported. But if I'd been there
from the start, I'd have used ontape anyway, and would commend it as a
solution. IMHO it's perfectly OK provided you know what you're doing and
you take due care.
