This is a library for exporting all messages of Gmail as a list using Google Apps Script (GAS).
Recently, I have had a situation it had been required to backup all messages in own Gmail. In order to achieve this, I created a simple script. After I created it, I thought that when such situation might occur for other users and the script is published as a library, they might be useful. So I created this library. But I created this for my situation. So if this cannot be used for your environment and an error occurs, I apologize.
This is a sample script for backing up a project as a zip file. When you use this script, please install a GAS library of ProjectApp2. You can back up both the standalone script type and the container-bound script type.
In this script, the blob of zip file can be retrieved from ProjectApp2. So you can also send it as email without creating a file.
var projectId = "### fileId of project ###";
var blob = ProjectApp2.getProjectBlob(projectId, true);
DriveApp.createFile(blob[0].setName("backupProject.zip"));
