A while back, I wrote a blog about changes to backup/restore functionality in SQL Server 2022: SQL Server 2022 – Time to Rethink your Backup and Recovery Strategy. Now, more exciting features are here in PowerStoreOS 3.5 that provide additional options and enhanced flexibility for protecting, migrating, and recovering SQL Server workloads on PowerStore.
Secure your snapshots
Backup copies provide zero value if they have been compromised when you need them the most. Snapshot removal could happen accidentally or intentionally as part of a malicious attack. PowerStoreOS 3.5 introduces a new feature, secure snapshot, to ensure that snapshots can't be deleted prior to their expiration date. This feature is a simple checkbox on a snapshot or protection policy that protects snapshots until they expire and can't be turned off. This ensures that your critical data will be available when you need it. Secure snapshot can be enabled on new or existing snapshots. Here’s an example of the secure snapshot option on an existing snapshot.
Once this option is selected, a warning is displayed stating that the snapshot can’t be deleted until the retention period expires. To make the snapshot secure, ensure that the Secure Snapshot checkbox is selected and click Apply.
Secure snapshot can be applied to individual snapshots of volumes or volume groups. The secure snapshot option can also be enabled on one or more snapshot rules in a protection policy to ensure that snapshots taken as part of the protection policy have secure snapshot applied.
Since existing snapshots can be marked as secure, this option can be used on snapshots taken outside of PowerStore Manager or even snapshots taken with other utilities such as AppSync. Consider enabling this option on your critical snapshots to ensure that they are available when you need them!
There's no such thing as too many backups!
If you're responsible for managing and protecting SQL Server databases, you quickly learn that it's valuable to have many different backups and in various formats, for various reasons. It could be for disaster recovery, migration, reporting, troubleshooting, resetting dev/test environments, or any combination of these. Perhaps you’re trying to mitigate the risk of failure of a single platform, method, or tool. Each scenario and workflow has different requirements. PowerStoreOS 3.5 introduces direct integration with Dell PowerProtect DD series appliances, including PowerProtect DDVE which is the virtual edition for both on-premises and cloud deployments. This provides an agentless way to take crash consistent, off-array backups directly from PowerStore and send them to PowerProtect DD.
To enable PowerStore remote backup, you need to connect the PowerProtect DD appliance to your PowerStore system as a remote system.
Next, you add a remote backup rule to a new or existing protection policy for the volume or volume group you want to protect, providing the destination, schedule, and retention.
Once a protection policy is created with remote backup rules and assigned to a PowerStore volume or volume group, a backup session will appear.
Under Backup Sessions, you can see the status of all the sessions or select one to back up immediately, and click Backup.
Once a remote backup is taken, it will appear under the Volume or Volume Group Protection tab as a remote snapshot.
From here, you can retrieve it and work with it as a normal snapshot on PowerStore or enable Instant Access whereby the contents can be accessed by a host directly from PowerProtect DD. You can even retrieve remote snapshots from other PowerStore clusters!
This is yet another powerful tool included with PowerStoreOS 3.5 to enhance data protection and data mobility workflows.
