Percona XtraBackup implemented support for Backup Locks.
Percona XtraBackup can now store backup history on the server itself in a special table created for that purpose.
Percona XtraBackup has been rebased on MySQL 5.6.17.
Fixed the InnoDB redo log incompatibility with 5.1/5.5 server and compressed tables which was introduced by the upstream fix in MySQL 5.6.11 that could make InnoDB crash on recovery when replaying redo logs created on earlier versions. Bug fixed #1255476.
Percona XtraBackup did not flush the InnoDB
REDOlog buffer before finalizing the log copy. This would only become a problem when the binary log coordinates were used after restoring from a backup: the actual data files state after recovery could be inconsistent with the binary log coordinates. Bug fixed #1320685.
innobackupex now sets
0before executing F
LUSH TABLES WITH READ LOCKif the server is a member of the Galera cluster. Bug fixed #1320441.
storage/innobase/xtrabackup/CMakeLists.txtnow honors the
XB_DISTRIBUTIONenvironment variable when configuring
innobackupex.plto innobackupex. Bug fixed #1320856.
Percona XtraBackup does not add XtraDB-specific fields when preparing a
backup of an upstream MySQL server. Bug fixed #988310.
Information about backup type and parameters is now stored in the
xtrabackup_info file in the backup directory. Bug fixed #1133017.
When backup locks are used,
xtrabackup_slave_infoshould be written under
BINLOGlock instead of
TABLElock. Bug fixed #1328532.
