Hi @George_Kechagias, thanks for your response. I was trying to perform backup and restore using xtrabackup for encrypted InnoDB tables using keyring mounted as extraPVC. After taking backup I tried to restore into a cluster where I had loaded the previous cluster’s master keys in the same component\_keyring\_file mounted as extraPVC here as well. But the restore job was failing with `2026-01-28T05:07:06.494451-00:00 0 [ERROR] [MY-011825] [Xtrabackup] Error reading xtrabackup_keys: failed to derive encryption key` `2026-01-28T05:07:06.494502-00:00 0 [ERROR] [MY-011825] [Xtrabackup] failed to load tablespace keys` I figured that it was because the restore pod didn’t have the keyring file mounted, but I was not sure how can I mount it and also ensure that component\_keyring\_file config is also present there. It would be great if you could help me with this, I also tried using transition-key but was facing a different issue there [Cannot specify custom --transition-key for XtraBackup in Percona PXC Cluster](https://forums.percona.com/t/cannot-specify-custom-transition-key-for-xtrabackup-in-percona-pxc-cluster/40129) Thanks --- _[View the full topic](https://forums.percona.com/t/how-to-mount-keyring-using-extrapvc-in-percona-1-19-0/40078)._
