For this example, consider an IQ database consisting of a single catalog
store dbspace named db.db with three main IQ dbspaces:
A, B and C.
- At time t0, alter all three
main dbspaces read-only.
- Copy db.db to db.db0,
either by shutting the database down and copying db.db or
using dbbackup to make a copy while the database
is still running.
- Freeze dbspaces A, B and C at
the hardware level. Store db.db0 in an immutable
form, perhaps by storing it in a file system file on the WORM device
and freezing it.
At this point, the database has been archived as of time t0 in
an immutable form.
