- `backend` - (obj) The backend stores [Terraform state files](https://www.terraform.io/docs/state/index.html) for each task. This option is similar to the [Terraform backend configuration](https://www.terraform.io/docs/configuration/backend.html). Consul-Terraform-Sync supports Terraform backends used as a state store. It does not support enhanced backends. If omitted, Consul-Terraform-Sync will generate default values and use configurations from the [`consul` block](#consul) to configure [Consul as the backend](https://www.terraform.io/docs/backends/types/consul.html). The Consul KV path is the base path to store state files for tasks. The full path of each state file will have the task identifier appended to the end of the path, e.g., `consul-terraform-sync/terraform-env:task-name`.
- Supported backend options: [azurerm](https://www.terraform.io/docs/backends/types/azurerm.html), [consul](https://www.terraform.io/docs/backends/types/consul.html), [cos](https://www.terraform.io/docs/backends/types/cos.html), [gcs](https://www.terraform.io/docs/backends/types/gcs.html), [kubernetes](https://www.terraform.io/docs/backends/types/kubernetes.html), [local](https://www.terraform.io/docs/backends/types/local.html), [manta](https://www.terraform.io/docs/backends/types/manta.html), [pg](https://www.terraform.io/docs/backends/types/pg.html) (Terraform v0.14+), [s3](https://www.terraform.io/docs/backends/types/s3.html)
- Visit the Terraform documentation links above for the specific backend configuration options.

- If omitted, Consul-Terraform-Sync will generate default values and use configurations from the [`consul` block](#consul) to configure [Consul as the backend](https://www.terraform.io/docs/backends/types/consul.html), which stores Terraform statefiles in the Consul KV. The [ACL token provided for Consul authentication](#token) is used to read and write to the KV store and requires [Consul KV privileges](https://learn.hashicorp.com/tutorials/consul/consul-terraform-sync-secure?utm_source=WEBSITE&utm_medium=WEB_IO&utm_offer=ARTICLE_PAGE&utm_content=DOCS#configure-acl-privileges-for-consul-terraform-sync). The Consul KV path is the base path to store state files for tasks. The full path of each state file will have the task identifier appended to the end of the path, e.g. `consul-terraform-sync/terraform-env:task-name`.
- The remote enhanced backend is not supported with the Terraform driver to run operations in Terraform Cloud. Use the [Terraform Cloud driver](#terraform-cloud-driver) to integrate Consul-Terraform-Sync with Terraform Cloud for remote workspaces and remote operations.
- `log` - (bool) Enable all Terraform output (stderr and stdout) to be included in the Consul-Terraform-Sync log. This is useful for debugging and development purposes. It may be difficult to work with log aggregators that expect uniform log format.
- `path` - (string) The file path to install Terraform or discover an existing Terraform binary. If omitted, Terraform will be installed in the same directory as the Consul-Terraform-Sync daemon. To resolve an incompatible Terraform version or to change versions will require removing the existing binary or change to a different path.
- `persist_log` - (bool) Enable trace logging for each Terraform client to disk per task. This is equivalent to setting `TF_LOG_PATH=<work_dir>/terraform.log`. Trace log level results in verbose logging and may be useful for debugging and development purposes. We do not recommend enabling this for production. There is no log rotation and may quickly result in large files.
