It’s annoying in that it can take up to a week for the first mail to reply. And you can’t automate it, so no automatic backups.
But these limits are weird because while file size limits do exist, they don't match Google's limits: 4GB is the limit for regular zip, zip64 has a limit of 16 exabytes. And TGZ's limit of 50GB shows that they they have the internal infrastructure to support building larger files too.
So, other than that most of their customers use Windows and they want to make takeout as annoying as possible, do they put that limit on it?
The frequent failures to generate my takeout are annoying though.
