This was data loss on GCE "persistent disks" (equivalent to AWS EBS), not
archival storage. Hopefully very few people are using persistent disks as
*backup* storage (if nothing else, it's more expensive).
The general point is still valid, though -- *any* single instance of data is
vulnerable to loss, whether it's on your computer, or someone else's.
Backups are never optional.
