Hi Laurent,
ha, our mails just crossed their ways :)

Yes. You can get this list with 'collect':
: (select +Backup)
{5-1} (+Backup)
hostName "software-lab"
basePath ("erp")
startDT "2012-07-31 21:20:57"
name "2012-07-31 21:20:57"
: (collect 'backups '+File (db 'startDT '+Backup "2012-07-31 21:20:57"))
-> (...)

Yes, that's what occurred to me, and I wrote it in my previous mail.
So, 'request' is correct in this case. Just, as I said, the difficult
point is to determine what the "identity" of a file means.
Cheers,
