In this post I am going to share how to backup Portworx Data Services (PDS) managed Kubernetes databases to Oracle Cloud Infrastructure (OCI) S3 Object Storage buckets.
OCI Object Storage
Create OCI Bucket
Logon to Oracle Cloud Infrastructure (OCI) and from the Dashboard select Object Storage or via the hamburger menu navigate to Storage -> Object Storage -> Buckets.
Select your required Compartment, and click Create Bucket
Provide a Bucket Name, and confirm storage options, for this post I will use the Standard Default Storage Tier.
OCI also provides an archive storage tier for long-term storage which may be of interest as it is one-tenth of the cost of Standard object storage
Note: Bucket names must be unique, if you have used the name even in another Compartment expect to see an error message.
By default the bucket is Private, however if required you can change the visibility by clicking on the 3 vertical ellipsis on the right hand side and updating it to Public.
Customer Secret Key
Before we can backup our PDS database to OCI we need to generate a Customer Secret for authentication.
From the OCI dashboard, Click on the Profile icon (top right), navigate to User Settings -> Customer Secret Keys and click Generate Secret Key providing a descriptive name.
Enter secret key Name
Once generated you will need to select Copy, this will be the Secret Key, which we will be using later.
Now, click on the newly created Secret Name to obtain the Access Key, again save this for later.
Object Storage Namespace Name
From the OCI dashboard, Click on your Profile icon (top right), navigate to Tenancy
The Object Storage Namespace and default S3 compartments should be visible.
Alternatively, you can use the OCI command line interface, for example.
% oci os ns get
{
"data": "<Object Storage Namespace>"
}
Portworx Data Services (PDS)
From the left hand panel click on Settings (gear icon) to access the settings options.
Click on Add Backup Credentials and select S3 Compatible.
Provide a Name, the OCI Access Key, Secret Key and Endpoint captured earlier.
The newly created Cloud Account should now be visible.
Click on Targets and select Add Backup Targets.
Select Cloud Account, enter Name, Bucket Name and Region, for example.
Click on the 3 vertical ellipsis, and select View Details, wait till the required Deployment Target has a green tick.
Backup Deployment
Now select Deployments from the left hand panel (disk icon) and click on type of deployment.
To Take Ad-hoc Backup, select Backup Target and click Backup
After a few minutes the backup job will appear in the Backup Jobs panel.
Oracle Object Storage
Return to OCI and navigate to the bucket, for example Storage -> Object Storage -> Bucket Details
It’s also possible to see details of the backup from the Kubernetes cluster by using pxctl cloudsnap status, for example.
% pxctl cloudsnap status --name 5b320cd7-5833-4881-882d-d4754ee276bb Defaulted container "portworx" out of: portworx, csi-node-driver-registrar NAME SOURCEVOLUME STATE NODE BYTES-PROCESSED TIME-ELAPSED ETA/COMPLETED 5b320cd7-5833-4881-882d-d4754ee276bb 455952688535669561 Backup-Done 10.225.115.188 481 MiB 7.331008066s Tue, 31 May 2022 15:51:35 UTC
