My Takeout for Gmail, Drive and Photos shows "in progress" for three days, and then an email said it failed. I want one backup of everything. What can I do?

Big exports fail more often. Try these changes:

1. Split it. Create separate exports, one for Gmail, one for Drive and one for Photos, and smaller groups inside Photos.
2. Choose a smaller archive size, like 2GB, so a single failure does not ruin one huge file.
3. Select "Send download link via email" and download soon, because links stay active only for 7 days.
4. Do not start several exports at once, and finish the earlier one first.
5. Download with a stable connection and a desktop browser. A download that stops can be resumed from the link in the email.

Gmail alone is usually done in minutes to hours. Photos with large videos is the part that takes days.

Separate exports worked. Gmail was ready in an hour. Drive and Photos arrived next day. Thanks.
