Having a 1TB file sucks in way more ways than just "your backup provider doesn't support it". Believe me.
Having a 1TB file sucks in way more ways than just "your backup provider doesn't support it". Believe me.
One example: A Git repository that I created contained files that are above GitHub's file size limits. The reason was a bad design in my program. I could fix this design mistake, so that all files in the current revision of my Git repository are now "small". But I still cannot use GitHub because some old commit still contains these large files. So, I use(d) BitBucket instead of GitHub.
Of course, all the commit identifiers change.
These old files nevertheless contain valuable data that I want to keep. Converting them to the new, much improved format would take serious efforts.
Are you really sure you cannot rebase/edit/squash the commits in that git repositories?
Yes, commit hashes will change, but will it actually be a problem?
This was just one example. Let me give another one:
In some industries for audit reasons you have to keep lots of old data in case some auditor or regulator asks questions. In such a situation, the company cannot say "hey sorry, we changed our data format, so we cannot provide you the data that you asked for." - this will immediately get the company into legal trouble. Instead, while one is allowed to improve things, perfect capability to handle the old data has to be ensured.
You can do that on shared repos too but that would cause a bad headache to other maintainers.
