InterSystems Data Platforms and performance – VM Backups and IRIS freeze/thaw scripts

This post explains strategies for backing up InterSystems IRIS databases using External Backup integrated with snapshot-based solutions, particularly on VMware. It covers IRIS's freeze/thaw mechanism that ensures database integrity during snapshots and discusses VM stun time considerations that may affect database mirroring failover. The post also compares IRIS Online Backup as a minimal built-in solution versus the recommended External Backup approach for scaling systems.
