Compare the existing PVC's capacity against the source volume size recorded in the backup volume info (#10506) before any side effect and skip the volume when it is too small, so the restore fails early instead of running out of space midway. For the block data mover the source size is the device size; for the file system data movers it is the logical size of the backed-up files, a lower bound since file system metadata is not accounted for. The file system path reads the size from the volume info already carried in RestoreData. The PVC CSI RIA has no access to the volume info, so the restore engine carries the size on the PVC item through a Velero-internal annotation, the same mechanism as the selected-node carrier; both carrier annotations are stripped before the item is created in the cluster. The check is skipped when the source size is unknown (backups taken before it was recorded) or the PVC's capacity is not reported. Signed-off-by: chlins <chlins.zhang@gmail.com>
Overview
Velero (formerly Heptio Ark) gives you tools to back up and restore your Kubernetes cluster resources and persistent volumes. You can run Velero with a public cloud platform or on-premises.
Velero lets you:
- Take backups of your cluster and restore in case of loss.
- Migrate cluster resources to other clusters.
- Replicate your production cluster to development and testing clusters.
Velero consists of:
- A server that runs on your cluster
- A command-line client that runs locally
Documentation
The documentation provides a getting started guide and information about building from source, architecture, extending Velero and more.
Please use the version selector at the top of the site to ensure you are using the appropriate documentation for your version of Velero.
Troubleshooting
If you encounter issues, review the troubleshooting docs, file an issue, or talk to us on the #velero-users and #velero-dev channel on the Kubernetes Slack server.
Community
Velero is an open community and we welcome your participation. The best way to get involved is to join our bi-weekly community meetings:
- Join the Velero community meetings, held bi-weekly, alternating between Beijing-friendly and US/Europe-friendly time zones.
- Subscribe to the project meeting calendar.
- Chat with us on the Kubernetes Slack
#velero-userschannel and join the mailing list.
See the community page for the full schedule and details.
Contributing
If you are ready to jump in and test, add code, or help with documentation, follow the instructions on our Start contributing documentation for guidance on how to setup Velero for development.
Governance
Velero's governance describes how the project is run, including the decision-making process, the roles and responsibilities of maintainers, and how to become a maintainer. Governance applies across the Velero org and is maintained at velero-io/.github.

Velero compatibility matrix
The following is a list of the supported Kubernetes versions for each Velero version.
| Velero version | Expected Kubernetes version compatibility | Tested on Kubernetes version |
|---|---|---|
| 1.18 | 1.18-latest | 1.33.7, 1.34.1, and 1.35.0 |
| 1.17 | 1.18-latest | 1.31.7, 1.32.3, 1.33.1, and 1.34.0 |
| 1.16 | 1.18-latest | 1.31.4, 1.32.3, and 1.33.0 |
| 1.15 | 1.18-latest | 1.28.8, 1.29.8, 1.30.4 and 1.31.1 |
| 1.14 | 1.18-latest | 1.27.9, 1.28.9, and 1.29.4 |
Velero supports IPv4, IPv6, and dual stack environments. Support for this was tested against Velero v1.8.
The Velero maintainers are continuously working to expand testing coverage, but are not able to test every combination of Velero and supported Kubernetes versions for each Velero release. The table above is meant to track the current testing coverage and the expected supported Kubernetes versions for each Velero version.
If you are interested in using a different version of Kubernetes with a given Velero version, we'd recommend that you perform testing before installing or upgrading your environment. For full information around capabilities within a release, also see the Velero release notes or Kubernetes release notes. See the Velero support page for information about supported versions of Velero.
For each release, Velero maintainers run the test to ensure the upgrade path from n-2 minor release. For example, before the release of v1.10.x, the test will verify that the backup created by v1.9.x and v1.8.x can be restored using the build to be tagged as v1.10.x.
