# Configuring SAP HANA Persistent Log Backups

The SAP HANA database can produce a large number of log files that you must back up to successfully restore your database.

By default, the SAP HANA agent runs one persistent log backup job for each SAP HANA database.

The agent gracefully shuts down the Commvault persistent pipeline, and marks the backup job as complete when any of the following conditions are met:

- There is a job failure

- The specified time period expires

- There is no log activity for one hour

After the Commvault persistent pipeline is shut down, the next log request starts the process with a new job ID.

You can disable the persistent log backup feature using an additional setting. When you disable the feature, the agent backs up each log file as separate backup jobs.

- You must add the nPersistentLogBackup additional setting.
