We run client/server with full redundancy,
Redundant servers, redundant clients, redundant remote viewers, and a
"wayback" machine running RDCatch as record, and 168 hours later, playback.
Redundant sound cards ( ASI livewire ) are in the redundant servers.
Even wayback is redundant, with one on-site, and one off-site.
The off site is configured in a way that while it has a full copy of the
entire audio store, and the database current to within 24 hours, it can not
"run" that database or audio store. It's strictly off-site backup, current
to within less than 24 hours.
None of this except replication is automatic !
If it fails in a catastrophic way, that's a big enough deal I want
everyone to know about it, so it gets tended to ASAP.
Now, we also have redundant Cisco switches, even redundant CAT cable to
each location, so no one item is permanently fatal.
Each identified single point of failure has a redundant device, either hot
or cold backup next to, above, or below it.
Even in the event the building becomes a smoking hole in the ground, there
is a full backup available, and 7 days to get it up and running.
I once saw a RAID-5 fail, where the first disk had failed months prior,
but because it automatically kept going, no one knew until it failed
in a non-recoverable catastrophic way.
