Percona XtraBackup now reads server options from
SHOW VARIABLESrather than
Percona XtraBackup now has more verbose output during initial table scan (it will now print a diagnostic message before performing a tablespace scan, which may take a long time on systems with large numbers of tablespaces) and before starting a backup/apply-log/copy-back operation in innobackupex (it will now print a diagnostic message with a timestamp to make it easier for users to get duration of the operation.)
innobackupex didn’t take the default
datadir, which caused backups to fail if the
datadirwasn’t specified in the
my.cnfconfiguration file. Bug fixed #936934.
innobackupex will now fail with an error when innobackupex –slave-info is used on a multi-threaded non-GTID slave, because
Exec_Master_Log_Poscannot be trusted for a multi-threaded slave. Bug fixed #1372679.
--decompressweren’t marked as mutually exclusive, ie. if they were both specified, only
--decompresswould work, which could lead to MySQL instance being started with an unprepared backup. Fixed by making mutually exclusive categories of options: 1.
--apply-log. Bug fixed #1376874.
innobackupex wasn’t creating directories specified in
--copy-backoption was used. Bug fixed #1382347.
Percona XtraBackup now supports all option modifiers supported by upstream MySQL: skip, disable, enable, maximum, loose. Bug fixed #664128.
Percona XtraBackup would fail to perform a full backup on Percona Server 5.5 if
innodb_log_file_sizevariable wasn’t set in the
my.cnf. Bug fixed #1334062.
