About a week ago, a representative from the Norwegian Mapping Authority said in an interview that storing their data in some cloud service was not a viable solution: Last year, they had increased their saved data volume by two petabytes. He did not indicate the current total size.

Lots of people - even computer professionals - are rather careless with large units: Copying a megabyte file is almost instantaneous nowadays. A gigabyte file takes a little while, not that much time. The next size, only one higher... Smile | :) If copying a gigabyte takes 85 seconds, copying a terabyte takes a full day and night, 24 hours. A petabyte copied at the same speed would take three years. A thousand days. A coworker of mine, program developer for many years, and an eager photographer and home movie maker, bought an 8 TB disk for his home PC, copying all his video and photo stuff that over the years had been accumulating in his multi-disk NAS. But it woudn't copy... Only when he sat down to make an estimate of how long it "ought to" take (in his case: about two days) did he realize that it was copying fine.

At work, we can have (almost) all the disk space we want ... as long as we do not require backup of it. The cost of a raw disk is a drop in the ocean compared to the cost of backup. Ten years ago, we backed up our build servers, all desktop PCs, as well as a number of central servers. Today, the number of SW developers is a magnitude higher, and the disks are at least a magnitude bigger. So today, anything that can be restored from the VCS, can be rebuild or can be reinstalled from the central software repos, are no longer backed up. What can be considered duplicates, or recoverable information, we cannot afford to back up. The volumes are too immense. But of course: That requires that we have very reliable backup plans for the primary copies, and have working plans and procedures for recovering data when some secondary copy is lost.
