Is there a repo for Local where a fix can be contributed for this? Thanks!

Hey @bknight – Thanks for writing in and letting us know! We don’t have a public repo for Local core – but let me verify that I understand things correctly so I can replicate and write a good bug report!

Is the issue that there is one file that is larger than 2GB within the site backup, or is it that a site backup that is larger than 2GB will cause issues?

Thanks for the info.

The issue happens when there is 1 file that is >2GB. We encountered this when including our database export as part of the import.
