# Restore Log Data

> Use the Mezmo Data Restoration feature to restore log data from your archives to search, review, and analyze.

Mezmo's Log Data Restoration feature provides a way to re-ingest, or restore, archived logs from cold storage so you can [search and filter](https://docs.mezmo.com/2.8/docs/search-and-filter) logs and in the Mezmo user interface. Restoration is useful for troubleshooting older bug tickets, as well as bringing up additional context from older logs beyond your retention period.

## Feature Notes

* Your account must have [log archiving](https://docs.mezmo.com/2.8/docs/archiving) enabled to use the Log Data Restoration feature
* Mezmo supports restoration from [AWS S3 and Google Cloud Storage ](https://docs.mezmo.com/2.8/docs/export-logs-to-external-storage)archives
* On [AWS S3](/mezmo-developer-docs/2.6/docs/export-logs-to-external-storage), object ownership needs to be set to [object writer](https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-ownership-new-bucket.html#:~:text=Object%20writer%20\(default\))
* The Mezmo system requires **read** access to the stored logs
* By default, each restoration task will be ingested for the same period of time as your normal logs
* Data Restoration is included in [ the Pro, and Enterprise plans ](https://www.mezmo.com/pricing)
