Decrypting backup with the wrong key would make the backup unusable and unrecoverable. Bug fixed #1413044.
Fixed Percona XtraBackup assertion caused by dirty pages remaining in the buffer pool after the log was fully applied. Bug fixed #1368846.
Backup will not be prepared and innobackupex will stop with an error if the transaction log file is corrupted and it wasn’t applied to the intended LSN. Previously this was showing only as a warning. Bug fixed #1414221.
log-appliedis introduced for backup prepared with
--redo-onlyto avoid making the backup unusable by preparing full or incremental backup without
--redo-onlyand then applying next incremental on top of it. Incremental backup now can be applied only to backup in
log-appliedstate, but not to
full-preparedas it was earlier. Bug fixed #1436790.
