How to Back Up Gmail to Google Drive (3 Ways)
The short answer: Gmail has no built-in "save to Drive" button for email. To back up Gmail to Google Drive you can export your mailbox manually with Google Takeout, sync mail to a desktop client and copy the files up, or set an auto-forward rule that archives every email to Drive as it arrives. Only the last one runs by itself.
If you just want a one-time copy — before closing an account or leaving a job — use Method 1. If you want every future email backed up without lifting a finger, use Method 3. This guide covers all three, with the exact steps and the trade-offs of each.
Why back up Gmail at all?
Your Gmail account is a single point of failure. If it's locked — a flagged login, a policy violation you didn't know about, a forgotten recovery method — the years of receipts, contracts, confirmations, and records inside it are locked too. Google's own account recovery process exists, but it isn't guaranteed to succeed.
The distinction that matters: Google protecting Gmail against their hardware failures is not the same as you having a backup. A backup is a copy you control, in a place a Gmail lockout can't reach. Google Drive under the same account is better than nothing — Drive files survive many mail-specific problems, and you can share or move them — but for real independence, send the copy to a second Google account, another provider, or an S3 bucket.
Method 1: Google Takeout (manual export)
Google Takeout exports your entire mailbox and can drop the archive straight into your Drive.
- Go to takeout.google.com and click Deselect all.
- Scroll to Mail, tick it, and (optionally) choose specific labels instead of everything.
- Under delivery, set "Add to Drive" as the destination, pick a file type (
.zip) and size, then Create export. - Wait for the "your export is ready" email — large mailboxes can take hours or a day — then open the archive from Drive and verify it.
Good: complete, free, official, and it lands in Drive without a middleman. Bad: it's a snapshot, not a backup. The export is stale the moment it finishes, the download link expires, you have to remember to repeat it, and the result is one giant MBOX file inside the zip. To read a single message you'd normally import it into a client like Thunderbird — though our free MBOX viewer opens the export right in your browser, and the MBOX to EML converter splits it into one portable file per email.
Method 2: Desktop mail client over IMAP
Point Thunderbird (or Apple Mail, or Outlook) at your Gmail account over IMAP, let it download everything, then copy its mail storage into Drive.
- In Gmail: Settings → Forwarding and POP/IMAP → enable IMAP.
- Add the account to Thunderbird and set folders to sync for offline use.
- Back up Thunderbird's profile folder to Google Drive, manually or with Drive for desktop.
Good: you get a local, readable copy of everything, refreshed whenever the client runs. Bad: it only backs up while your computer is on and the client is open; the storage format is client-specific; and keeping the Drive copy current is on you.
Method 3: Auto-forwarding to an archiving address (automatic)
This is the only method that runs by itself. You forward Gmail to an address that archives every message to your Drive as a standard .eml file — the raw message with headers and attachments intact.
With InboxBucket the setup looks like this:
- Connect Google Drive to InboxBucket (it requests access to a single folder it creates, nothing else) and copy your private inbound address, e.g.
[email protected]. - In Gmail: Settings → See all settings → Forwarding and POP/IMAP → Add a forwarding address and enter that address.
- Gmail sends a confirmation to the new address — it appears in your InboxBucket dashboard; confirm it.
- Choose to forward all mail, or create Gmail filters to forward only what matters (receipts, contracts, specific senders).
From then on, every matching email lands in your Drive seconds after it arrives — as the original file, deduplicated by Message-ID so retries never double-store, with a visible delivery status. Forwarding a single important email by hand works exactly the same way. And because the destination is your storage, you can point it at a different Google account, OneDrive, Dropbox, or S3 instead — so the backup doesn't sit inside the same account it's insuring.
Good: continuous, automatic, provider-independent files you own. Bad: it archives from now onward — for the mail you already have, do a one-time Takeout export (Method 1) alongside it.

Which method should you use?
| Takeout | IMAP client | Forwarding archive | |
|---|---|---|---|
| Automatic | No | Partly | Yes |
| Backs up past mail | Yes | Yes | No (pair with Takeout) |
| File format | One MBOX | Client-specific | One .eml per email |
| Effort to restore one email | High | Low | Low |
| Runs without your computer | Yes | No | Yes |
| Can target storage outside Gmail | Yes | Yes | Yes |
The practical combination: one Takeout export for history, plus auto-forwarding for everything from today onward. That gives you the full past in Drive and every future email captured automatically, both in storage you control.
FAQ
Does Gmail have a built-in backup to Google Drive?
No. Gmail and Drive are separate Google products, and Gmail offers no setting that saves emails to Drive. Google Takeout can deliver a one-time MBOX export to Drive, but it must be triggered manually each time.
What happens to my attachments when I back up Gmail to Drive?
It depends on the format. A Takeout MBOX and a .eml archive both keep attachments embedded inside each message, exactly as sent — nothing is dropped. Printing an email to PDF, by contrast, saves only the visible page and leaves attachments behind, which is why PDF is a poor backup format.
Does backing up Gmail to Google Drive use my storage quota?
Yes, if the copy lands in the same Google account. Gmail and Drive share one 15 GB free quota, so a large export can fill it. To avoid that, send the backup to a different Google account or another provider entirely — an auto-forwarding archive can write to OneDrive, Dropbox, or S3 so it never touches your Gmail quota.
How do I back up Gmail before deleting my account?
Run a full Google Takeout export of Mail and confirm you can open it before you delete anything — deletion is irreversible and the export can take up to a day. If you'll keep receiving mail at a forwarding address, set up an archiving forward first so nothing sent during the transition is lost.
How often should I export with Takeout?
If Takeout is your only backup, quarterly is a reasonable floor for anything you'd mind losing. If a forwarding archive covers new mail automatically, a single initial export of your history is usually enough.
What format should email backups be in?
Prefer one .eml file per message. It's the standard RFC 822 format — headers, body, and attachments in a single file that opens in any mail client or text editor. MBOX works but bundles the whole mailbox into one file that's awkward to search and restore from.
