Hello,

Every day, I create a backup using MariaBackup, and restore the snapshot it on a Docker container.

The version in both the main server and the docker container is 10.5.9.

Usually, things go well, but recently I got two similar crashes due to "data structure corruption".
I confirm the version was 10.5.9 in both sides, on both incidents.

(many of these "Ignoring data file" logs)

Is there any way I can identify the problem here, or at least prevent this from happening?
I want to ensure all my backups are "clean" and "valid".

This may be related to the issue I reported about using "RENAME TABLE", MDEV-25568
It was in April 15 that I added a job that performs "RENAME TABLE" every 5 minutes on two tables, so I wonder if the fact that this incident happened twice after that day, may be the cause of this.

Thank you.
