Reporting bugs

Please read the known issues before reporting any new issues; we already know about several significant issues, including Gmail login failures (for which there is a robust work-around), and problems with logging phone calls into calendars (which we are investigating).

Description

This is a fork of the now-defunct Android backup tool SMS Backup. It uses Gmail/IMAP to perform SMS, MMS and call log backups over the network.

Main features/improvements:

Tested with Android 4.x (Ice Cream Sandwich) - 10.x. (Q)

SMS Backup+ is available for free in the Google Play Store and on F-Droid, there will never be a pro / paid version.

But if you find the app useful and want to support its development you can make a donation using the secure in-app Play Store payment mechanism.

To get updates more frequently join the beta programme or download the latest beta manually from Github releases.

Also make sure to read the Privacy Policy.

Usage

First steps

You need to have an IMAP account or a Gmail account with IMAP enabled. See Use IMAP to check Gmail on other email clients to learn how to enable IMAP for your Gmail account or look at this screenshot.

After starting SMS Backup+, tap on "Connect" to start the authorization process.

👉 1.5.11: You will first have give SMS Backup+ the permission to access your account, displayed as "Allow SMS Backup+ to access your contacts?".

If you consent you have to confirm the Gmail account to be used for the backup.

If you don't have a Google account registered on your device a browser window will appear to perform a web-based authentication as fallback.

After completing the authorization process the "Connect" switch should be activated, indicating success. You are now ready to perform the first backup.

👉 1.5.11: "Connected" changed from checkbox to switch.

Initial backup

It is important that you perform the first backup manually. SMS Backup+ needs to know whether you want to upload messages currently stored on your device or not.

After having connected your Gmail account, SMS Backup+ will ask you to perform a first backup. If you choose "Backup", SMS Backup+ will start backing up all your messages to Gmail.

If you choose "Skip", nothing is sent to Gmail and all messages currently stored on your device are simply marked "backed up". This option is handy if you previously uninstalled SMS Backup+ and do not want to send your messages again to Gmail. Please note that any messages arrived after you last uninstalled SMS Backup and this initial backup won't ever be backed up to Gmail.

👉 1.5.11: Before the backup starts you will have to grant "send and view" permissions for SMS.

Restoring

If you wish to restore messages back to your phone tap "Restore". By default all messages stored on Gmail will be restored (this can be changed in "Advanced Settings").

👉 1.5.11: Default changed to 500 messages.

You can safely restore to a phone which has already messages stored on it, SMS Backup+ will skip the existing messages.

Before the restore can start you will need to confirm the change of the default SMS app. This step is required to get further permissions to write messages (see also the corresponding FAQ entry).

Call log support

SMS Backup+ can also backup and restore your call logs. It stores all calls using a separate label (defaults to Call log, but can be changed in "Advanced settings"). If you wish you can set this to the same value as SMS, to make all backups use the same label.

The body of the call log message contains the duration of the call in seconds followed by the phone number and call type (incoming / outgoing / missed).

An example:

267s (00:04:07)
+44123456789 (incoming call)

You can also add call log entries to a Google calendar. Just select Calendar sync in Advanced settings, and make sure you have selected a calendar to sync with.

If you only want to backup specific call types (incoming, outgoint etc.) you can do so as well.

👉 1.5.11: Call log backup is disabled by default. Permissions need to be confirmed separately for phone and calendar access.

<a id="RCS-support">Rich Communication Services</a>

Rich Communication Services is currently not supported, nor are there any plans to support it. Rich Communication Services is also known as RCS, Advanced Messaging, Advanced Communications, joyn or Message+.

<a id="3rdparty">3rd party app integration</a>

If you want to trigger backups from another app, enable 3rd party integration in Advanced Settings and send the broadcast intent com.zegoggles.smssync.BACKUP. This will work even when Auto Backup is disabled.

Usage without Gmail (IMAP)

You don't have to use Gmail to backup your text messages - change Authentication to "Plain text" in "Advanced settings - Custom IMAP server", then change the server address / user name and password accordingly. Make sure to set security to "SSL (optional / trust all)" if your IMAP server has a self-signed certificate ("Unknown certificate" error during backup).

👉 1.5.11: security settings have been simplified. Select TLS and check "Trust all certificates" if using a self-signed certificate.

Also note that Gmail labels simply correspond to IMAP folders that will automatically get created on the first backup.

<a id="faq">FAQ</a>

If you don't find an answer here you can also visit the Google+ community which might be able to help.

<a id="faq-general">General questions</a>

<a id="faq-general-file-bug-report">I want to file a bug report, what should I do?</a>

First search Github issues to see if the bug has already been reported. If not, create a new issue and attach the following details:

If it is related to backing up / restoring you should also enable the sync log with "Extra debug information" enabled (in "Advanced settings") and attach a relevant portion of it. The sync log is stored as sms_backup_plus.log (in the directory Android/data/com.zegoggles.smssync/files).

👉 1.5.11: new log file path, was previously on external storage / sdcard.

Rather than including the log in the text of your issue description, please use the "attach image" feature to attach your logfile as text to your issue. Alternatively, create a gist and link to it from your issue description.

It might also be worth to install the current beta version of SMS Backup+ to see if the bug is also present in the development version.

<a id="faq-general-can-you-add-feature-x">Can you add feature X?</a>

Over the years a lot of features have been added, often as a result of requests by users. This has worked great initially but has made the product itself very unfocussed and generic. It started as a tool to back up text messages (as the name SMS Backup implies) but gradually more and more features were added (call logs, MMS, WhatsApp...). It's now at a point where it has become too heavy and difficult too maintain or use. The settings screen makes this obvious, there are just too many things to configure. If anything features should be removed at this point, not added. A more focussed product would be easier to maintain and use.

Right now, SMS Backup+ is in maintenance mode; no new features will be added. Existing bugs will of course be addressed.

<a id="faq-general-permissions">Why does it need so many permissions?</a>

👉 1.5.11 introduces runtime permissions (Android 6.0+) which means that you only grant the permissions for the features you actually use, after installing the application.

<a id="faq-general-package-not-signed">When updating the app I get 'Package file was not signed correctly'</a>

Try uninstalling the app, then installing the new version. Make sure to select "Skip" when doing the first backup, otherwise messages will get backed up twice.

<a id="faq-backup">Backup questions</a>

<a id="faq-backup-automatic-backup">Automatic backup does not work / stopped working</a>

If the automatic backup does not work first make sure that a manually initiated backup works as expected.

👉 1.5.11 brings many improvements to auto-backup reliability. However some beta users have still reported problems. If the backups don't run automatically try changing the Android "Battery optimization" settings for SMS Backup+ to "Don't optimize".

When reporting a bug related to auto backup it is essential to attach a sync log file. See the relevant FAQ for more information on how to do this.

<a id="faq-backup-show-imap">I get the one of following errors during backup/restore: Command: SELECT "SMS"; response: #6# [NO, Unknown, Mailbox; SMS, [Failure]] (or response: #6# [NO, [NONEXISTENT], unknown mailbox: SMS (failure)])</a>

Make sure you have the "Show IMAP" option checked in the Gmail label settings:

Screenshot

If this is the case make sure that the label name is set correctly (capitalization matters!).

<a id="faq-backup-reset">How can I make the app think that it has to do the backup again?</a>

Select "Reset" from the menu, and confirm that you want to reset the current sync state. All messages on the phone will be backed up on the next run.

<a id="faq-backup-only-received">Only received messages are backed up, not the ones I sent</a>

Do you use a non-standard app like Google Voice/Hangouts or Signal to send messages? It could also be a device specific problem. Related issues: 516, 841.

<a id="faq-backup-inbox">Why do backed up SMS show up in my inbox?</a>

This is probably related to Gmail's automatic priority inbox filing. A workaround is to set up a filter with "subject: SMS with", let the filter mark it as not important.

<a id="faq-backup-to-inbox">I want the backed up messages to show up in my Gmail inbox!</a>

Just set the label to "Inbox" instead of the default "SMS" or "Call log".

<a id="faq-backup-schedule">What's the difference between regular and incoming backup schedule?</a>

Incoming backup schedule is used for incoming messages. 3 minutes here means that any incoming SMS will trigger a backup after 3 minutes. It is a full backup (including any sent messages). You should set the incoming schedule to a low value if you want to make sure that incoming SMS show up in Gmail shortly after arrival.

Regular schedule is used to perform backups in specific intervals. 2 hours here means that the device will try to backup all messages every 2 hours.

Fewer updates performed by the app means less energy consumed, so there's a trade-off data protection vs. battery life.

<a id="faq-backup-scheduling">I'd like SMS Backup+ to schedule a backup only at a given time of the day / when Wifi is available / etc.</a>

If you require more control over the backup schedule than what SMS Backup+ already provides you can use a 3rd party app to trigger the backup. Tasker for example supports SMS Backup+ since version 1.0.14.

<a id="faq-backup-gmail-100">The app saves only 100 SMS/MMS per contact!</a>

This seems to be a limitation of Gmail. After the first hundred or so SMS being backed up, Gmail will cease to properly thread many of the conversations. You will notice that Gmail will eventually treat each SMS (in that initial backup) as individual conversations and will not longer group/thread them together.

A way around this is to do a full backup 100 SMS at a time (see Advanced settings).

<a id="faq-backup-threading">In Gmail, I'd like to have all messages listed chronologically and not ordered by who sent them.</a>

It's a Gmail feature, but you can disable it. In Gmail settings, set conversation view to off (screenshot).

<a id="faq-backup-does-it-sync">When I delete a text locally, will it delete the saved copy on Gmail?</a>

No. SMS Backup+ does not do a "real" sync, once the text has been transferred to Gmail it won't get modified or deleted by the app.

<a id="faq-backup-untrusted-certificate">I get the error "Trust anchor for certification path not found"</a>

This means that it is impossible to establish a trusted connection with the IMAP server. A few reasons why this might happen:

You can try to set the IMAP Server Setting Security to SSL (optional / trust all).

👉 1.5.11: Added "Trust all certificates" option

<a id="faq-restore">Restore questions</a>

<a id="faq-restore-default-app">Why does SMS Backup+ ask to become the default SMS app?</a>

Google has changed the way SMS permissions work starting with Android 4.4 (KitKat). In order to get write access to your messages an app has to be set as the default system SMS app. Before starting the restore operation SMS Backup+ will request your permission to be set as default app. After restoring you will be asked to set the previous choice (usually "Messaging") back as default. ⚠️ This last step is important, if you don't set the old default back you might lose new messages.

<a id="faq-restore-MMS">Are there any plans to support restoring of MMS?</a>

No, for a variety of reasons: MMS are highly carrier-dependent, documentation is lacking and the Android Emulator does not support them.

However SMS Backup+ is open source; patches are more than welcome.

<a id="faq-restore-many-messages">I'm not able to restore all of my (insert huge number) messages!</a>

SMS Backup has not been designed to restore many thousands of messages. See the question "How do I restore the last N weeks / N messages?" for a way around that.

<a id="faq-restore-partial">How do I restore the last N weeks / N messages?</a>

If you have a lot of messages backed up (let's say over 5000) restoring can be very slow, especially if you're only interested in the most recent messages.

A workaround is to use the Gmail web interface (or an IMAP email client) to move the bulk of the messages to another label in Gmail (e.g. SMSARCHIVED), and only keep a few hundred or so messages in the SMS label.

Next time you restore it will only restore those messages and it will be a lot faster.

<a id="faq-authentication">Authentication questions</a>

<a id="faq-authentication-revoke-access">How can I revoke the app's access to my Gmail account?</a>

Go to Authorized Access to your Google Account and select "Remove Access" next to "SMS Backup+".

<a id="faq-authentication-request-token">When connecting, I get 'Could not obtain request token...'</a>

If you get this error message and your network connection is active double-check that your time zone settings are correct, and that the local time is displaying correctly. The authentication process won't work otherwise.

<a id="beta">Beta testing</a>

If you want to help beta testing, visit the Play Store beta page. You will be asked to opt in to the beta program (you can leave it anytime).

Once opted in your device will automatically update to the latest beta which might have bug fixes and features not found in the currently released version.

Alternatively you can download an APK from Github releases and install it manually (⚠️ you won't get automatic updates this way). You can also install via F-Droid which often has more recent versions than what is available on the Play Store.
