- Don't edit it manually. tfstate was designed to be manipulated by terraform and not by users directly.
- Store it in secured location (since it can include credentials and sensitive data in general)
- Backup it regularly so you can roll-back easily when needed
- Store it in remote shared storage. This is especially needed when working in a team and the state can be updated by any of the team members
- Enabled versioning if the storage where you store the state file, supports it. Versioning is great for backups and roll-backs in case of an issue.
