--- Quote from: Ian.M on April 08, 2021, 12:04:37 pm ---It would be nice if WebNX added a large NAS with its own power management in a shipping container at both their locations, with high bandwidth connectivity into their data centers.   Its only a bit over 600 miles as the crow flies between their locations, (729 miles by road, est. 10.5H driving time), so if they had another extended outage, the whole NAS could be shipped to their other location to facilitate getting fall-back servers online without the bandwidth implications of either uploading from off-site backups, or live syncing over a significant geographical distance.  They'd also need a priority standby contract with a local shipping company at each end to provide a self-loading container truck and two drivers with N hours notice 24/7.

First off, SAN, not NAS. Secondly, such an off-site backup requires fat pipes anyway for read and write, e.g. 100 Gbps Ethernet. So moving the SAN around won't speed up things. Actually it would cause a delay by the transport and also would add the risk of being damaged during transport, by a traffic accident for example.

Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.

This has made me consider my own data safety and the importance of having an off-site backup of at leat the most critical things.

I have in front of me a 1TB microSD card, 15 x 11 x 1mm thick (fascinating hi-res X-Rays here). That works out at roughly 6GB per cubic millimetre.

Assuming we have a VW Passat (which claims 1780 litres of cargo space with the rear seats down), our modern equivalent of the station-wagon-full of tapes is potentially something like 1780 x (100 x 100 x 100) x 6GB, or around 10 exabytes (10x10^9 GB).

And yes I know we wouldn't get that capacity, they're slow to write to, and so on and so on, but it does make one think.
