Comment 58 for bug 1470250

@f-bosch Hi Frederik, we're really sorry that this backup-can-cause-filesystem-remounted-readonly issue has been there for long time! We definitely want to get it fixed as soon as possible. Unluckily according to my understanding of the long thread here, I think we had difficulty trying to reproduce the issue -- it looks it happens randomly and it appears in your environment every 1~2 days (?).

The good news is: in #57, it looks Joseph found a reliable way to reproduce the issue within 1 hour. Joseph, after you confirm the reliable way, can you please share the detailed exact steps -- these are very important for us to debug the issue.

BTW, it looks the issue is Ubuntu-specific (CentOS doesn't have the issue according to Bug Description).
