Application-Aware Backup Strategies for ActiveMQ & Hazelcast

Hello Commvault Experts,
 

I'm dealing with a time synchronization issue in our setup where Hazelcast is missing its 5-second heartbeats, presumably due to 30-second time leaps during our backup snapshots. This results in dropped connections and servers hanging, a problem that emerged suddenly.
 

We suspect that Commvault snapshot operations might be causing this. Would application-aware backups be the right approach to prevent such disruptions, especially for time-sensitive applications like Hazelcast and ActiveMQ? If so, what specific application-aware backup configurations does Commvault support for these applications?

 

Any insights on strategies to maintain operational integrity during backups would be highly valuable.

Thanks for your help.

Do you create VM-level backups? If so, than you might be seeing issues due to quiescing. Can you leverage IntelliSnap?

Thanks for the suggestion @Onno van den Berg !

We create VM-level backups, which has been paused due to the ongoing issues?

We're a bit cautious with Intellisnap though – our NetApp HCI platform has been buggy, and it’s phasing out soon. We're actually planning to switch platforms in a year, so we're trying to avoid new complexities by introducing it.

It’s weird, these app issues just started, even with our usual quiescent snaps enabled earlier. We're thinking about switching to application-aware backups, but I'm pretty new to this area. Any advice on what type of app-aware backup might work best here?


Also wont Intellisnap create native snaps too in it’s workflow?

@Nik  I do not think application aware backups are going to change anything in this scenario. Appaware backups are for specific applications and listed here:

https://documentation.commvault.com/2023e/essential/106406_application_support_for_hypervisors.html#supported-application-versions

Do these applications have a guide or best practice with backups?

Thanks
