Additional backup strategies

{{site.data.keyword.on-prem-fname}}: [{{site.data.keyword.on-prem}}]{: tag-red}

The additional backup strategies that you can use are as follows:

IBM teams and managed services

{: #teams-managed-services}

You can engage IBM teams and services to assist you throughout the migration lifecycle.

Image capture

{: #backup-image-capture}

Image capture produces a storage FlashCopy of the logical partition (LPAR) and works on both AIX, Linux, and IBM i LPARs. You can use image capture to store VM images within your account (locally) as a part of your image catalog, directly to IBM Cloud Object Storage, or both.

Importing and exporting images requires a considerable amount of processing power and network bandwidth. As a result, you can submit only one import or export request before it is queued. Typically, users import or export system disks (AIX rootvg disks) that are smaller in size (less than 1 TB) to facilitate the transfer to and from Cloud Object Storage. If your image size is greater than 1 TB, your transfer might take a long time and be prone to failure. The maximum uncompressed image size that you can import or export is 10 TB.

Cloud Object Storage

{: #cos-over-directlink}

The preferred ways to connect to Cloud Object Storage from a VM in {{site.data.keyword.powerSys_notm}} are as follows:

  1. In a PER workspace, attach the {{site.data.keyword.powerSys_notm}} workspace to a Transit Gateway and directly access the Cloud Object Storage direct endpoint. See, Attaching Transit Gateway to a PER workspace.

  2. In a non-PER workspace that are in a multi-zone region (MZR) the best way to connect to Cloud Object Storage is as follows:

    1. Create a Virtual Private Cloud (VPC) with subnets in the same region as your {{site.data.keyword.powerSys_notm}} workspace.
    2. Create a Virtual Private Endpoint gateway (VPE).
    3. Connect the VPC to a Transit Gateway.
    4. Create a cloud connection to connect the non-PER {{site.data.keyword.powerSys_notm}} workspace to the same Transit Gateway.

    The {{site.data.keyword.powerSys_notm}} would then use the VPE's IP address to connect to Cloud Object Storage. A Custom Resolver (CR) is needed by the {{site.data.keyword.powerSys_notm}} to reach the Cloud Object Storage. If the VPE has multiple IP addresses, you can set up custom DNS and a custom hostname to connect to Cloud Object Storage.

  3. Deploy a Nginx reverse proxy server in either the classic or VPC infrastructure.

    Nginx is a mature, compact, and fast open source web server that excels at specialized tasks, including the reverse proxy server role. For information on setting up a Nginx reverse proxy server, see Installing your Nginx reverse proxy.

Cloud Object Storage on AIX

{: #cos-aix}

IBM Power Systems that are running AIX 7.2 TL3, or later, have a script that is located in the path /usr/samples/nim/cloud_setup. The cloud_setup command installs the command-line environment for cloud storage services.

cloud_setup [-I | G | C] [-v]

-I: Install the necessary RPMs for universal CLI (supports Cloud Object Storage).
-G: Install the necessary RPMs for gsutil CLI (Google Cloud Storage).
-C: Install the necessary RPMs for cloud-init.
-v: Enable debug output.

  1. To begin, copy the file to the system that requires AWS and give it run permission.

  2. Enter the cloud_setup -I command to install the AWS CLI and all of the dependant RPMs.

  3. After the installation is complete, you must configure awscli for access to Cloud Object Storage and provide the correct region (where your bucket Cloud Object Storage is defined) in the aws --endpoint-url s3 command. In the following example, the us-east region is used:

# export PATH=$PATH:/opt/freeware/bin

# aws configure
AWS Access Key ID [None]: d197axxxxxxxxxxxxxxxxxxxxxxxxxxxa4
AWS Secret Access Key [None]: f52a5xxxxxxxxxxxxxxxxxxxxxxx001a33b74d8
Default region name [None]: us-east
Default output format [None]: json

# aws --endpoint-url https://s3.us-east.cloud-object-storage.appdomain.cloud s3 ls
2019-01-28 13:32:40 poweriaastest

# aws --endpoint-url https://s3.us-east.cloud-object-storage.appdomain.cloud s3 ls s3://poweriaastest
