Xtrabckup error after update mysql to version 8.0.30: File ./ib_logfile0: 'open' returned OS error 71. Cannot continue operation

Oi @CESAR_MURILO_DA_SILV .

Xtrabackup 8.0.29 is not compatible with MySQL 8.0.30 . We are still working on a new release to merge 8.0.30 changes and make it compatible but we are still on the early stages of understanding those changes. For now I would suggest to rollback to 8.0.29 or using logical backup.
