Answer
Lightning Payroll backup files use the .LPB extension. You can restore a local backup file or an online backup depending on where your backup is stored.
In the Desktop App
To restore a local backup file, click Tools >> Restore Backup. A wizard opens ÔÇö select your .LPB file and follow the prompts. The app automatically saves a copy of your current data before restoring, so you can undo the restore if needed.
To restore from an online backup, click Tools >> Online Backups. Log in to the online backups server, then click Restore next to the backup you want. See How Can I Set Up Online Backups? for details on registering and using this feature.
To undo a recent restore, click Tools >> Revert Last Restored Backup. This rolls the data back to the automatic copy the app saved immediately before your last restore.
In the Online (Web/Mobile) App
To restore a local backup file, go to Tools >> Restore Backup. The Restore Local Backup screen lets you upload an .LPB file from your computer. Click Upload & Restore to apply it. This overwrites your existing company data. Restore Backup is not available on trial accounts.

To restore from an online backup, go to Tools >> Online Backups, log in, and click Restore next to the backup you want.
To undo a recent restore, go to Tools >> Revert Last Restored Backup and click Yes, let's revert. This returns your data to the state it was in immediately before the last restore or sync.
