Gmail backup guide

How to keep an automatic, read-only copy of Gmail

A reliable Gmail backup starts with least-privilege access, a complete first copy, and incremental checks that can recover from expired history checkpoints.

What you will finish with

An independent Gmail copy

  • Mail and its embedded attachments copied without send or delete access
  • A dashboard showing the number of preserved items and last verification
  • A portable ZIP you can keep outside Mycopy
  1. Step 1

    Create your Mycopy account

    Register, verify that you can sign in, and open Home. Your connected source and its archive are always tied to this Mycopy account.

  2. Step 2

    Choose Gmail as your first source

    In Choose your first source, select Connect Gmail. When Google connection keys are not yet enabled, Mycopy shows Setup guide instead.

  3. Step 3

    Check the Google permission

    Sign in to the correct Google account. Mycopy requests your basic account identity, offline access for scheduled backups, and read-only Gmail access. That permission still allows Mycopy to view all Gmail messages and settings. Stop if the screen asks to send, modify, or delete mail.

  4. Step 4

    Approve and return to Mycopy

    Select Allow. Google returns you to Mycopy, where the first historical backup is queued. Mycopy stores connection tokens encrypted and never receives your Google password.

  5. Step 5

    Let the first copy finish

    You can close the page while messages are copied in resumable batches. The current Gmail connection preserves messages returned by Gmail’s standard message list, which excludes Spam and Trash. Later runs add new messages since the last history checkpoint; if that checkpoint expires, Mycopy starts a full mailbox sync.

  6. Step 6

    Read the custody status

    On Home, check the source status, total preserved item count, and last verified time. Compare the total with what you reasonably expect from Gmail. The MVP does not yet show per-folder or attachment counts, so use a local export for a deeper check.

  7. Step 7

    Download and inspect a local copy

    Select Download local copy. Open the ZIP, then inspect manifest.json and an EML file inside the items folder with a desktop mail app. A successful recovery test is stronger evidence than a status label.

Disconnecting Google later

Revoking Mycopy in your Google Account stops future Gmail access. It does not delete mail already preserved in Mycopy; downloading or deleting that stored copy is a separate action.

Prefer a manual copy?

Google Takeout creates an MBOX snapshot without connecting Mycopy to Gmail. Follow the Google Takeout guide and keep the original ZIP as your provider-issued copy.
