Android Data Backup: aborted by rate limiter

问题

I have successfully backed up data from my device. On reinstallation, I get my first backup data restored. But my problem is further calls to backup don't get the data sent or saved by the Transport.

When I make calls to the Backup service, this is my log:

D/BackupManagerService(748): Now staging backup of com.company.app
D/PerformBackupTask(748): invokeAgentForBackup on @pm@
I/BackupRestoreController(748): Getting widget state for user: 0
I/PerformBackupTask(748): no backup data written; not calling transport
D/PerformBackupTask(748): starting agent for backup of BackupRequest{pkg=com.company.app}
D/BackupManagerService(748): awaiting agent for ApplicationInfo{fe3f4f5 com.company.app}

I/BackupManagerService(748): got agent android.app.IBackupAgent$Stub$Proxy@2de849d4
D/PerformBackupTask(748): invokeAgentForBackup on com.company.app
D/BackupHelperDispatcher(31817): handling existing helper 'data_file' android.app.backup.FileBackupHelper@34d086c5

I/GmsBackupTransport(11651): K/V backup for com.company.app aborted by rate limiter. next=1437068418200, current=1436978369321
I/BackupManagerService(748): Backup pass finished.

Two lines concern me:

I/PerformBackupTask(748): no backup data written; not calling transport

I/GmsBackupTransport(11651): K/V backup for com.company.app aborted by rate limiter. next=1437068418200, current=1436978369321

Are these normal ?

When I do make subsequent calls to backup, I can see my data being stored locally in my designated file, so I can only assume the issue is with the Transport.

I'm wondering if I need to version my data in some way?

Does the Transport overwrite existing data by default?

回答1:

The "aborted by rate limiter" message gives you two dates in epoch format (i.e. next=1483295674399, current=1483213981015).

You cannot do backup before the date/time stated by next. To know which time is that go to http://www.epochconverter.com/.

Meanwhile you can use other transport as stated by the previous answer.

For "aborted by rate limiter", you can try bmgr list transports, and bmgr transport WHICH to switch to the local transport which seems has no rate limit.

$ adb shell bmgr list transports
    android/com.android.internal.backup.LocalTransport
  * com.google.android.gms/.backup.BackupTransportService
$ adb shell bmgr list transports
  * android/com.android.internal.backup.LocalTransport
    com.google.android.gms/.backup.BackupTransportService
