 `BACKUP_WAIT_SECONDS` | `0` | The backup script will sleep this many seconds between re-starting stopped containers, and proceeding with archiving/uploading the backup. This can be useful if you don't want the load/network spike of a large upload immediately after the load/network spike of container startup.
 `BACKUP_HOSTNAME` | `$(hostname)` | Name of the host (i.e. Docker container) in which the backup runs. Mostly useful if you want a specific hostname to be associated with backup metrics (see InfluxDB support).
 `AWS_S3_BUCKET_NAME` |  | When provided, the resulting backup file will be uploaded to this S3 bucket after the backup has ran.
+`AWS_GLACIER_VAULT_NAME` |  | When provided, the resulting backup file will be uploaded to this AWS Glacier vault after the backup has ran.
 `AWS_ACCESS_KEY_ID` |  | Required when using `AWS_S3_BUCKET_NAME`.
 `AWS_SECRET_ACCESS_KEY` |  | Required when using `AWS_S3_BUCKET_NAME`.
 `AWS_DEFAULT_REGION` |  | Optional when using `AWS_S3_BUCKET_NAME`. Allows you to override the AWS CLI default region. Usually not needed.
