A baseline backup is a periodic backup of baseline updates only.

Baseline backups are always useful. In particular, they are useful when your baseline updates are so fast that you can recover from failures by rerunning baseline updates.

Performing baseline backups works well in implementations in which you run baseline or delta updates only, without having to run partial updates. In these cases, it is sufficient to back up baseline update files so that you can recover the index by restarting the MDEX Engine with the dgraph_input directory reconstructed from a baseline backup.
