README

Recently added options to enable usage of an S3 appliance: Cloudian
HyperStore:
        --s3_backup_aws_endpoint <host:port> (port is required)
        --s3_backup_force_path_style=true/false
        --s3_backup_log_level <level> can be one of: LogOff, LogDebug, LogDebugWithSigning, LogDebugWithHTTPBody, LogDebugWithRequestRetries, LogDebugWithRequestErrors.  Default: LogOff

By default the s3 client will try to connect to
<path>.<region>.amazonaws.com.  Adjusting the endpoint will allow this
to be changed.

Given the way the FQDN is configured the TLS certificate may not match the
server's "base" (<region>.<end_point_address>) due to the leading <path>
so setting --s3_backup_force_path_style=true will force the s3 client to
connect to <region>.<endpoint> and then make a request using the full
path within the http calls.

--s3backup_log_level enables more verbose logging of the S3 calls.

Overview

Package s3backupstorage implements the BackupStorage interface for AWS S3.

AWS access credentials are configured via standard AWS means, such as: - AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables - credentials file at ~/.aws/credentials - if running on an EC2 instance, an IAM role See details at http://blogs.aws.amazon.com/security/post/Tx3D6U6WSFGOK2H/A-New-and-Standardized-Way-to-Manage-Credentials-in-the-AWS-SDKs

type ClosedConnectionRetryer

type ClosedConnectionRetryer struct {
	// contains filtered or unexported fields
}

ClosedConnectionRetryer implements the aws request.Retryer interface and is used to retry closed connection errors during MultipartUpload operations.

func (*ClosedConnectionRetryer) MaxRetries

func (retryer *ClosedConnectionRetryer) MaxRetries() int

MaxRetries is part of the Retryer interface. It defers to the underlying aws Retryer for the max number of retries.

func (*ClosedConnectionRetryer) RetryRules

func (retryer *ClosedConnectionRetryer) RetryRules(r *request.Request) time.Duration

RetryRules is part of the Retryer interface. It defers to the underlying aws Retryer to compute backoff rules.

func (*ClosedConnectionRetryer) ShouldRetry

func (retryer *ClosedConnectionRetryer) ShouldRetry(r *request.Request) bool

ShouldRetry is part of the Retryer interface. It retries on errors that occur due to a closed network connection, and then falls back to the underlying aws Retryer for checking additional retry conditions.
