Restore PVC Data

This section describes the functionality and requirements related to pvcdata restore.

Local Directory Restore

The procedure to restore a PVC Data archive file to a local directory is essentially the same as restoring the Kubernetes Object configuration file as described in Restore to Local Directory. However, output transformation is unavailable and ignored when restoring PVC data.

If the PVC uses a filesystem volume mode, the restore creates a tar archive file you can manually inspect and use. If the PVC uses a block volume mode, the data creates a raw archive file (or a compressed file if compression was enabled during backup), which you can manually mount and use on your system.

Restore to PVC

This procedure is similar to the one described in PVC Data backup and uses the same Bacula Backup Proxy Pod image. During restore, the plugin uses the same endpoint configuration parameters so it is not necessary to configure it again. If the endpoint parameters have changed, you can update them using Bacula plugin restore options modification as in the example below:

*restore select all done where=/

When restoring PVC data, the plugin restores all data from the backup archive for the selected Persistent Volume Claim. Existing data is overwritten regardless of the Replace setting. Be aware of this behavior; it may change in a future release.
