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.
A few years back I worked at a home. They organised the whole data structure but needed to move to another Providor. I and my colleagues moved roughly just about 15.4 TB. I don’t know how long it took because honestly we didn’t have much to do when the data was moving so we just used the downtime for some nerd time. Nerd time in the sense that we just started gaming and doing a mini LAN party with our Raspberry and banana pi’s.
Surprisingly the data contained information of lots of long dead people which is quiet scary because it wasn’t being deleted.
