Hello, I’m downloading a backup from an external server and restoring it on a docker container volume. I’m currently running percona-server:57 docker image [Docker Hub](https://hub.docker.com/r/percona/percona-server).

I followed all the steps mentioned in this guide, [The Backup Cycle - Full Backups - Percona XtraBackup](https://www.percona.com/doc/percona-xtrabackup/2.4/backup_scenarios/full_backup.html#restoring-a-backup) to restore the backup but It doesn’t seem to work.

When I look at the docker logs I see this:

Any ideas on what I could try to fix this?

Hi @betancourtl

By looking into your error message, seems like you are trying to start `mysqld` passing `--initialize` flag but the data-dir already has files on it. Since you are starting a MySQL using a restored backup as a source of data, you can skip --initialize.

If that doesn’t help to solve your problem. Please describe the steps you are taking to restore your backup as well as the full docker command used to start your container

Looks like the issue was related to file permissions. Thx for the help!
