You can create custom service level agreement (SLA) policies for persistent volumes that
are attached to a Kubernetes or Red Hat®
OpenShift® cluster. You can define the frequency of
snapshot and backup operations and specify policies for retention, replication, and copy
jobs.
Before you begin
During a container backup operation, a snapshot is always
created. When a scheduled backup job runs, a snapshot of a persistent volume claim (PVC) is created
on your storage system at the frequency that is defined by the snapshot policy. You can specify
additional policy settings to copy the snapshot to the IBM Spectrum® Protect
Plus vSnap server or directly to a cloud storage
system.
- Using a cloud storage system as primary storage
- If you plan to copy data directly to a cloud storage system, the cloud target must have a
defined backup object storage bucket. For instructions about adding a cloud storage provider, see
Managing cloud storage.
The following cloud storage systems are supported for
container workloads:
- Amazon Simple Storage Service (Amazon S3)
- IBM Cloud® Object Storage
- Microsoft Azure Blob storage
- S3 compatible storage
Limitations:
- For IBM Cloud Object Storage, support for
retention-enabled vaults is not available.
- For S3 compatible storage, generic S3 support is based on external certification processes. For
the list of supported S3 compatible providers, see technote 1087149.
- Using the vSnap server as primary storage
-
If you copy data to the vSnap server, additional options are available to replicate the vSnap
server and to copy the data to a secondary backup storage provider that is a cloud storage system or
a repository server. For snapshots that are copied directly to cloud storage, replication and
secondary backup storage options are not available.
If you plan to copy data to a vSnap server, take the following actions:
- To copy data from a vSnap server to secondary storage, such as a cloud storage system or
repository server, ensure that the secondary storage is configured. For information about the
secondary storage systems that are supported and for configuration instructions, see Managing backup storage.
- To archive data from a vSnap server to a cloud storage system, the cloud target must have a
defined archive bucket. To add an archive bucket for a cloud storage system, follow the instructions
in Managing cloud storage.
If you plan to copy data to a vSnap server, take the
following actions:
- If you plan to copy data from a vSnap server to secondary storage, such as a cloud storage
system or repository server, ensure that the secondary storage is configured. For information about
the auxiliary storage systems that are supported and for configuration instructions, see Managing backup storage
- If you plan to archive data from a vSnap server to a cloud storage system, the cloud target must
have a defined archive bucket. To add an archive bucket for a cloud storage system, follow the
instructions in Managing cloud storage.
About this task
You can create custom SLA policies if you do not want to use the predefined
Container policy. The
Container policy initiates the
following operations:
- Snapshot backup operations every 6 hours with a retention period of 1 day
- Copy backup operations daily with a retention period of 31 days
A snapshot is required in a container backup operation.
When a scheduled backup job runs, a snapshot of the persistent volume claim (PVC) is created on your
storage system at the frequency that is defined by the snapshot policy. You can specify additional
policy settings to copy the snapshot to the IBM Spectrum Protect
Plus vSnap server, replicate the vSnap server, or
copy the data to object storage in the cloud or to a repository server.
If a PVC is associated with multiple SLA policies, ensure that the policies that you create are
not scheduled to run concurrently. Either schedule the SLA policies to run with a significant amount
of time between them, or combine them into a single SLA policy.
Procedure
To create an SLA policy for your PVCs, complete the following steps:
-
In the navigation panel, click
.
-
Click Add SLA Policy to open the Add policy
wizard.
- Select Containers in the Category
list.

rules page.
- Complete the following options on the page and then click
Next.
- Enter a name that provides a meaningful description of the SLA policy.
- Optional: Select Disable all schedules to create
the SLA policy without defining a frequency or start time. Policies that are created without a
schedule can be run on demand.
If you plan to enable the Backup Policy section for copy backup operations
to a vSnap server or object storage, do not select this checkbox. If you select the checkbox,
no snapshots will be available for copying to the vSnap server or cloud object storage.
- In the Snapshot Protection section, set the following options
for snapshot operations:
