# s3
|
|
|
|
Stores the state as a given key in a given bucket on [Amazon S3](https://aws.amazon.com/s3/).
|
|
|
|
-> **Note:** Passing credentials directly via config options will
|
|
make them included in cleartext inside the persisted state.
|
|
Use of environment variables or config file is recommended.
|
|
|
|
~> **Warning!** It is highly recommended to enable
|
|
[Bucket Versioning](http://docs.aws.amazon.com/AmazonS3/latest/UG/enable-bucket-versioning.html)
|
|
on the S3 bucket to allow for state recovery in the case of accidental deletions and human error.
|
|
|
|
## Example Usage
|
|
|
|
```
|
|
terraform remote config \
|
|
-backend=s3 \
|
|
-backend-config="bucket=terraform-state-prod" \
|
|
-backend-config="key=network/terraform.tfstate" \
|
|
-backend-config="region=us-east-1"
|
|
```
|
|
