A client ran a bulk import that overwrote key contact properties across thousands of records. Lifecycle stages, lead scores, custom segmentation fields, all silently replaced with bad values from a misaligned CSV column. By the time of the 'oh s**t' moment, the damage was days old.

Unfortunately, they were not on the enterprise-level restore. The property history shows exactly what changed, but there's no native way to reverse it at scale on that tier. It was just days of manual spreadsheet work.

That incident pushed us to build a proper backup and restore layer for HubSpot, Notion, and Figma because the native safety nets have real gaps depending on your tier.

Triple-check your CSV mappings before importing, and consider using a third-party backup/restore tool (under the SaaS shared-responsibility model, HubSpot secures the infrastructure, your data is your responsibility).

We're building this restore layer and looking for a few testers to give us feedback. DM if interested.
