Velero vs VolSync

Velero is an open-source tool for backing up and restoring Kubernetes resources and persistent volumes, recovering from data loss, and moving resources between clusters. Backups can cover an entire cluster or selected resources chosen by namespace or label. Recurring schedules and pre- and post-backup hooks support repeatable operations. Velero can restore after data loss and migrate resources, including replication from production to development or test clusters. Its server runs on Kubernetes, while a command-line client runs locally. Storage integrations include maintainer-supported plugins for AWS, Google Cloud, Microsoft Azure, and VMware vSphere, plus community-maintained options. The plugin architecture also permits custom storage integrations and backup or restore behavior. Velero can be used in cloud or on-premises environments with object storage and, optionally, supported block storage. Installation requires access to a Kubernetes cluster, kubectl, a compatible object storage provider, and at least one plugin. File system backup is not installed by default. The project provides community support through GitHub and Kubernetes Slack.
