func (*EC2Session) CreateSnapshots ¶

func (e *EC2Session) CreateSnapshots(backupInfo *config.EBSBasedBRMeta) (map[string]string, VolumeAZs, error)

CreateSnapshots is the mainly steps to control the data volume snapshots. It will do the following works. 1. determine the order of volume snapshot. 2. send snapshot requests to aws.

func (*EC2Session) CreateVolumes ¶

func (e *EC2Session) CreateVolumes(meta *config.EBSBasedBRMeta, volumeType string, iops, throughput int64) (map[string]string, error)

CreateVolumes create volumes from snapshots if err happens in the middle, return half-done result returned map: store id -> old volume id -> new volume id

func (*EC2Session) DeleteSnapshots ¶

func (e *EC2Session) DeleteSnapshots(snapIDMap map[string]string)

func (*EC2Session) DeleteVolumes ¶

func (e *EC2Session) DeleteVolumes(volumeIDMap map[string]string)

func (*EC2Session) HandleDescribeVolumesResponse ¶

func (e *EC2Session) HandleDescribeVolumesResponse(resp *ec2.DescribeVolumesOutput) (int64, []*string)

func (*EC2Session) WaitSnapshotsCreated ¶

func (e *EC2Session) WaitSnapshotsCreated(snapIDMap map[string]string, progress glue.Progress) (int64, error)

WaitSnapshotsCreated waits all snapshots finished. according to EBS snapshot will do real snapshot background. so we'll check whether all snapshots finished.

func (*EC2Session) WaitVolumesCreated ¶

func (e *EC2Session) WaitVolumesCreated(volumeIDMap map[string]string, progress glue.Progress) (int64, error)
