I’m writing a program that wraps around dd to try and warn you if you are doing anything stupid. I have thus been giving the man page a good read. While doing this, I noticed that dd supported all the way up to Quettabytes, a unit orders of magnitude larger than all the data on the entire internet.
This has caused me to wonder what the largest storage operation you guys have done. I’ve taken a couple images of hard drives that were a single terabyte large, but I was wondering if the sysadmins among you have had to do something with e.g a giant RAID 10 array.
My cousin once stuffed an ISO through my mail server in '98. His connection up in Bella Bella restricted non-batched comms back then, so he jammed it through the server as email to get on the batched quota.
It took the data and passed it along without error, albeit with some constipation!
