Percona XtraBackup to AWS S3: Issue Alert

lorraine.pocklingtonlorraine.pocklington Percona Community ManagerLegacy User Role Patron
UPDATE: we have released fixes for this issue, if you use Percona XtraBackup in this scenario where AWS S3 is used as storage for backup files, please upgrade to the latest version. Here are the release notes:

https://www.percona.com/doc/percona-xtrabackup/2.4/release-notes/2.4/2.4.18.html
https://www.percona.com/doc/percona-xtrabackup/8.0/release-notes/8.0/8.0.9.html

We want to make you aware that, based on information shared with Percona via forum posts and a bug report, a recent change by Amazon to the configuration of AWS S3 is causing the upload of automated backups from Percona XtraBackup via xbcloud to AWS S3 to fail.


This is not a security incident, and no data has been compromised, however, stable production uses of Percona XtraBackup may experience issues.

Our engineers are working urgently on a fix, but in the interim please take the necessary steps to secure backup files in a way that does not depend on xbcloud uploads to AWS S3. While xbcloud uploads are impacted, you can upload files to AWS S3 manually using AWS CLI.

We will release further information as it becomes available.
