Recovering Deleted Files from an Amperity SFTP Server

Overview

If a file is accidentally removed from an Amperity-managed SFTP location, customers often ask whether the file can be restored or retrieved from a backup.
This article explains Amperity’s SFTP file retention policy and what options are available.


Important to Know About SFTP File Retention

In Amperity, SFTP locations are designed for data delivery and ingestion, not long-term storage.

Key points:

  • Files on Amperity SFTP servers are not backed up

  • Files are retained for a limited time window

  • Once a file is deleted or expires, it cannot be recovered

Because of this, Amperity Support cannot restore deleted SFTP files.


Why Files Cannot Be Restored

  • SFTP locations do not maintain historical backups or archives

  • Deleted files are permanently removed after the retention period

  • Amperity does not store copies outside the SFTP location

This behavior is expected and applies to all customers.


What You Can Do Instead

If a required file is missing:

  • Re-generate the file from your source system

  • Re-upload the file to the SFTP location

  • Maintain your own backups before uploading files to SFTP

These steps ensure data can be recovered if a file is removed accidentally.


Best Practices

  • Keep a local or cloud backup of all files sent to SFTP

  • Treat SFTP as a transfer location, not a storage system

  • Re-upload files promptly if ingestion fails

  • Monitor file delivery and retention timelines


Summary

Amperity SFTP servers do not retain backups of uploaded files.
If a file is deleted or expires, it cannot be recovered, and the file must be re-created and uploaded again from the source system.
