Manual method
- On your Android phone, open Settings, Google services, All services, then Backup under backup/restore.
- Confirm the destination Google Account and enable the message/device-data categories you need.
- Use Back up now, keep the phone connected, then inspect backup details and the completion time.
- For a readable record on your drive, save important messages and attachments individually. A third-party exporter is a separate choice: check its permissions and SMS/MMS/RCS coverage before using it.
What you get: Google documents SMS/MMS backup and RCS backup when using Google Messages. This supports restoration during device setup; it is not a downloadable MBOX/CSV conversation archive. Other messaging apps and managed/work devices have different coverage. Provider instructions.
Size and waiting time
Planning example: 1 GB; light/heavy scenarios: 0.005–20 GB. These are estimates, not a measured population average or fixed limits. Text itself is small; MMS and RCS pictures/video dominate this illustrative messages backup size. Other device-backup categories are excluded from the estimate.
Preparation: Google says backup and restoration can each take up to 24 hours. A larger full-device backup takes more space than the messages-only planning figure.
Network transfer of 1 GB: about 19 min at 10 Mbps, 4 min at 50 Mbps, or 2 min at 100 Mbps. This assumes 70% sustained throughput and excludes preparation, manual work and extraction. This is a comparison for transferring the messages-only amount. Google’s recovery backup uses upload speed and may also contain other device data. Transfer calculations and large-file examples.
Store and check your archive
The Google backup is held in the selected account for device restoration; this method does not produce an independent file to put on a USB key or external drive. Store individually saved messages and attachments in an encrypted computer folder, with an external-drive copy and an encrypted online copy. A USB key can carry an additional copy. Budget for the full device backup as well as messages.
Record the destination account and last successful backup time. Review the restore requirements before replacing the phone and keep the old phone until its messages have been recovered. Check manually saved records offline so they remain useful without the original app. Storage and recovery instructions.
