Yes, we frequently review revision history, and it’s not unusual for us to go back about a decade. Unfortunately, prior to that, source control wasn’t used, and that has made some tasks fairly difficult. A great example is data migration. Infrastructure changes over time, even if only gradually. Databases get upgraded and moved around. Recently we realized that some data we migrated nearly a decade ago had significant inconsistencies. We didn’t have full revision history, but what we did have was enough to piece together the puzzle over a period of several weeks. If we had full revision history—which would’ve gone back about two decades—the job would’ve been much easier.
