I have two hockey puck dive computers (1 Suunto and 1 Aeris)
For local NC diving I sling an AL19 = (1/4 of an AL80)
So complete redundancy.
Also two cutting tools, spare mask. Depending on dive may have two lights.

As for regs all of my regs are the same. HOG D-1's with Classic or SE seconds on primary and back up with back mounted doubles, another set of the same on each Sidemount bottle, and all stage regs are the same as well. You want regs that perform the same on all your gas supplies and once you start getting into multiple sets, that all take the same service kits.
As for computers, the primary one is my brain using tables cut on v planner and an OMS bottom timer. The back up if you want to call it that is a Shearwater Predator.
If lights are not really required I have two. If they are then it's three. A 21 Watt HID or 12 Watt Led canister and two Dorcy Penetrators. Since this is the technical forum I am guessing you are looking for tech answers.
Redundant air is via doubles with an isolator, Sidemount with a pair of LP 75.5's or LP 95's or maybe a couple al 80's, Stages are either 30, 40, or 80 cu ft aluminums.

I have 2x Scubapro Mk25 & S600 for backgas. Apeks XT50s for deco.
I use Scubapro/Uwatec bottom timers, but am considering the X-Deep as a future upgrade (pending some reviews/time to bed-down in the market).

I have all HOG regs, primary, backups, stages, o2, etc for sidemount.
My single tank backmount regs are some random collection of stuff I got from friends because I got too lazy to keep breaking my sidemount set up LOL. 1st stage HOG, 2nd stages who knows. I like my HOG stuff, and the only reason for the other random stuff is because I got them for a killer deal.
for computers i have Shearwater Petrel, Cochran Commander (old/first computer, want to replace with a 2nd Petrel) and backup tables cut and written on my slate for technical stuff.
for open water stuff I just dive my Petrel only along with one of my many dive watches I collect.
Lights are HOG 21W HID primary with multiple intova LED backups.
For lift, redundant bladders in my sidemount rig, for OW backmount I just carry a lift bag for backup.
Reels/spools are all in multiples.
line cutters are in multiples.
line markers are in multiples.
I have a backup mask I carry too when cave diving, but not usually for OW.
I also (if not boat diving) carry backup tanks in the vehicles. You never know when one will have issues, get left open, a friend forgot one (meaning you also aren't diving now), etc.

On doubles:..HOG 1st and 2nd's for primary and backup...Oceanic VT3 (w/transmitter) for primary and HOG black face analog SPG, w/a Sunnto Vytec DS (no transmitter) as backup/bottom timer....Carry Apeks DS4 and XTX50 as spare.....Lights; UK 440lumen eLED L1's on each hand and DRIS 'Shorty' and Intova WA as backups.......Carry spare 'heads' and xtra batteries for those and the computers.......Rebreather is totally different........

I'm new to DIR/GUE, and dive only Recreational at this time. But I carry two lights (both LED) and two computers plus run the basic 32% GUE tables in front of each dive. My computers are a Suunto D9 and an Aeris Epic that I keep in a pocket. My regs are a bit hodgepodge, the 1st stage and primary being ScubaPro Mk11/C300, with an old (but well maintained) detuned Aqualung Micra on a necklace.

on my doubles I run zeagel flat top VI for primary back gas with the right post being sealed. my second stages are Zeagel Onxy bright yellow cover for the take reg, grey for the keep reg.
my backups or stage bottles are Hollis DC4s with 221 seconds.
primary computer is a dive rite Nitek Q with a Zeagel N2ition as a backup and a v-planner table taped to my dive slate.

Doubles and deco/stage regs are all cave-ringed Atomic M1s; parts and maintenance are simplified, reg controls/clean out steps are all the same, all regs breathe thesame, not worried about moving a backgas reg to a deco bottle in an emergency, etc.
Computers are two Petrels running VPM, with Vplanner cut tables and an analog dive watch and depth gauge backing them up.
Some other things have three backups (lights, cutters), others two (SMBs, reels long enough for a from the bottom deployment, mask).
I’m not sure how I’d classify the level of redundancy/number of backups on isolated doubles…maybe two because of the two tanks, maybe three because technically it’s one tank I can break into two, maybe zero because in the event of a manifold failure coupled with a reg problem on the wrong post, I could theoretically lose access to all backgas absent the ability to swap a backgas reg underwater or feather the valve. Theoretical debates aside, conservative gas planning plus regular valve drilling gives me confidence that I will at minimum be able to preserve sufficient backgas to escape to my first deco gas depth from almost any conceivable emergency situation.

I dive a rebreather so my bailout is my redundancy. I always have two lights (a third can light if penetration is predicted), two cutting devices, two predators, spare mask, wet notes, two smb, two reels.
