You can create custom service level agreement (SLA) policies for
persistent volumes that are attached to a Kubernetes or OpenShift® cluster. You can define the frequency of snapshot and backup operations and specify
policies for retention, replication, and copy jobs.
Before you begin
If you plan to copy data to secondary storage or to archive data to a cloud storage system, take
the following actions:
- If you plan to copy data 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 secondary backup storage
- If you plan to archive data 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 runs the
following operations:
- Snapshot backups every 6 hours with a retention period of 1 day
- Copy backups 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 the Ceph® 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 pane, click .
-
Click Add SLA Policy.
The New SLA
Policy pane is displayed.
- In the Name field, enter a name that provides a meaningful
description of the SLA policy.
- Click Kubernetes, OpenShift.
The SLA policy options for Kubernetes or OpenShift clusters are displayed.
- In the Snapshot Protection section, set the following options for
snapshot operations:
- Retention
- Specify the retention period for the snapshots.
- Disable Schedule
- Select this checkbox to create the snapshot policy without defining a frequency or start time.
Policies that are created without a schedule can be run on demand. This field is optional.
- If you plan to enable the policy sections for copy backup, replication, or additional copy
operations, ensure that this checkbox is not selected. Otherwise, no snapshots will be available for
copying to the vSnap server.
- Repeats
- Enter a frequency for snapshot operations. Enter a frequency for snapshot
operations. Choose from Subhourly, Hourly,
Daily, Weekly, Monthly, or
Yearly. When Weekly is selected, you may select one or
more days of the week. The Start Time will apply to the selected days of the
week.
- Start Time
- Enter the date and time when you want the snapshot operation to start.
- The time zone is
automatically populated with your browser settings. To update the time zone, click the field and
select a region and city from the list, for example: Europe/Dublin. You can
also click the field and enter a region or city in the Search field, and
select an item from the matching results.
- Snapshot Prefix
- Enter a prefix to add to the beginning of snapshot names. You can add a prefix to snapshot names
to help you organize and easily identify snapshots. This field is optional.
- You can enter up to 32 characters for the prefix.
- For example, if you entered the prefix "daily", all snapshot names that are created with this
SLA policy will begin with "daily".
- Optional:
In the Backup Policy section, set the following options for copy backup
operations to the vSnap server:
- Backup Storage
- Select this checkbox to enable copy backup operations to the vSnap server. These operations
occur on the vSnap servers that are defined in the window.
- Retention
- Specify the retention period for the copy backups on the vSnap server.
- Disable Schedule
- Select this checkbox to create the backup policy without defining a frequency or start time.
Policies that are created without a schedule can be run on demand. This field is optional.
- Frequency
- Enter a frequency for copy backup operations.
- Start Time
- Enter the date and time when you want the copy backup operation to start.
Tip: Allot
time for the snapshot backup to complete before starting the copy backup operation. For example, if
the snapshot operation starts at midnight (0:00), set the copy backup operation to start 15 minutes
later, at 00:15.
- The time zone is
automatically populated with your browser settings. To update the time zone, click the field and
select a region and city from the list, for example: Europe/Dublin. You can
also click the field and enter a region or city in the Search field, and
select an item from the matching results.
- Target Site
- Select the target site for backup copies.
- A site can contain one or more vSnap servers. If more than one vSnap server is in a site, the
IBM Spectrum Protect
Plus server manages data placement in the
vSnap servers.
- Only sites that are associated with a vSnap server are shown in this list. Sites that are added
to IBM Spectrum Protect
Plus but are not associated with a vSnap
server are not shown.
- Only use encrypted disk storage
- If your environment includes encrypted and unencrypted servers, select this checkbox to back up
data to encrypted vSnap servers.
-
Restriction: If this option is selected, but no encrypted vSnap servers are available,
the associated job fails.
- Optional:
Under Replication Policy, set the following options to enable
asynchronous replication from one vSnap server to another. For example, you can replicate data from
the primary to the secondary backup site.
Replication partnerships requirement: These options apply to
established replication partnerships.
To add a replication partnership, see
the instructions in Configuring backup storage partners.
