Recovering Your Data from a
Malfunctioning Gateway or VM
Recovering Your Data from a Malfunctioning Gateway
or VM
If your gateway or virtual machine malfunctions, you can recover data that has been uploaded to AWS
and stored on a volume in Amazon S3. For cached volumes gateways, you recover data from a recovery
snapshot. For stored volumes gateways, you can recover data from your most recent Amazon EBS
snapshot of the volume. For tape gateways, you recover one or more tapes from a recovery point to a
new tape gateway.
If your cached volumes gateway becomes unreachable, you can use the following steps to recover your
data from a recovery snapshot:
1. In the AWS Management Console, choose the malfunctioning gateway, choose the volume you want
to recover, and then create a recovery snapshot from it.
2. Deploy and activate a new volume gateway. Or, if you have an existing functioning volume gateway,
you can use that gateway to recover your volume data.
3. Find the snapshot you created and restore it to a new volume on the functioning gateway.
4. Mount the new volume as an iSCSI device on your on-premises application server.
For detailed information on how to recover cached volumes data from a recovery snapshot, see
Cached Gateway is Unreachable And You Want to Recover Your Data (p. 332)
If your tape gateway or the hypervisor host encounters an unrecoverable failure, you can use the
following steps to recover the tapes from the malfunctioning tape gateway to another tape gateway:
1. Identify a tape gateway you want to use as the recovery target or create you can create a new one.
2. Disable the malfunctioning gateway.
3. Create recovery tapes for each tape you want to recover and specify the target tape gateway.
4. Delete the malfunctioning tape gateway.
For detailed information on how to recover the tapes from a malfunctioning tape gateway to another
tape gateway, see
You Need to Recover a Virtual Tape from a Malfunctioning Tape Gateway (p. 335)

Retrieving Your Data from an Irrecoverable Volume
If the status of your volume is IRRECOVERABLE, you can no longer use this volume.
For stored volumes, you can retrieve your data from the irrecoverable volume to a new volume by using
the following steps:
1. Create a new volume from the disk that was used to create the irrecoverable volume.
2. Preserve existing data when you are creating the new volume.
3. Delete all pending snapshot jobs for the irrecoverable volume.
4. Delete the irrecoverable volume from the gateway.
For cached volumes, we recommend using the last recovery point to clone a new volume.
