Google Vault is a legal hold tool that allows you to manage and export your google data for discovery purposes. Everlaw can process Google Vault files either directly via a cloud connector or from exported files.
From Vault, you can create exports that consist of actual data files (in a series of zips) and two Google-generated metadata files: one with custodian information and another with file metadata. When you generate an export in Vault, you can download these files individually. There will be a checksum file that can be ignored. To load the files with the metadata overlay on Everlaw first submit all files in a single folder or archive (see similar format for split archives/images).
Here is an example of Google Vault export files:
The Vault files must have their original filenames as downloaded from Google Vault. Then, you can drag and drop a folder (Google Chrome) or create a combined Zip of the above files to upload (other browsers).
