The following is a list of issues, including those attributed to third-party products, known to exist at the time of release.
Table 2. General known issues The plug-in name has been changed to use the “Plug-in for <product>” naming convention (that is, Plug‑in for MySQL). If you upgrade the plug-in for a system that is managed by a NetVault Backup Server 9.2 or earlier, a consequence of the name change is that savesets created with the upgraded plug-in are not displayed in the NVBU Restore window when the Selection Method is set to Plugin; only savesets created with an earlier version are displayed.Workaround for NetVault Backup Server 9.2 or earlier: On the Selections tab of the NVBU Restore window, select Job in the Selection Method list to view savesets or backups created with a previous version or the upgraded plug-in.
Default setting of lower_case_table_names system variable affects MySQL behavior on Mac OS X – The inconsistent behavior of case-sensitivity of MySQL on Mac OS X platforms affects the ability of the plug-in to restore backups. To ensure that you accommodate this inconsistency, be aware of the following when using the plug-in with Mac OS X:
• If the lower_case_table_names system variable is set to 1, incremental restores work correctly for databases that were created using lowercase, uppercase, or mixed-case names. (Additionally, the database names are displayed in the NetVault Backup Console using lowercase letters regardless of how the actual names were created.)
• If the lower_case_table_names system variable is set to 2 (this is the default setting on Mac OS X), incremental restores only work correctly for databases that were created using lowercase names. (Additionally, the database names are displayed in the NetVault Backup Console using the same format with which they were created.) Selecting Enable MySQL Replication but not configuring replication causes backups to fail – If you select the Enable MySQL Replication check box on the Configure dialog but do not configure replication, backups will fail. To correct this issue, either clear the Enable MySQL Replication check box on the Configure dialog or set up replication and execute the backup job again.
Under certain conditions, all InnoDB tables are backed up – All InnoDB tables in a MySQL instance are backed up if either of the following conditions is met:
1 Example: You have a MySQL Instance with two databases (DB1 and DB2). Each database contains two tables: DB1 has T1_InnoDB and T1_MyISAM and DB2 has T2_InnoDB and T2_MyISAM. If you back up T1_MyISAM and T2_MyISAM, T1_InnoDB and T2_InnoDB are also backed up. If you include one of the InnoDB tables, only that InnoDB table is backed up. If you select one of the databases, only the tables in the database are backed up.
2 Example: You have a MySQL Instance with two databases (DB1 and DB2). Each database contains two tables: DB1 has T1_InnoDB and T1_MyISAM and DB2 has T2_InnoDB and T2_MyISAM. If you back up DB1 and DB2 and exclude T1_InnoDB and T2_InnoDB, T1_InnoDB and T2_InnoDB are also backed up. If you exclude only one of the two InnoDB tables, only the other InnoDB table is backed up.This reflects current MEB (mysqlbackup utility) behavior, which might change in a future release (post-3.8.1).

• Plug‑in for MySQL 4.4 requires NetVault Backup 8.6.1 or later. For complete supported-platform information, refer to the Dell NetVault Backup Plug-in Compatibility Guide.
• Upgrades and new installs of MySQL – As explained in Bug 68807 for MySQL ( ), mysql_install_db ignores /etc/my.cnf in MySQL 5.6. Because MySQL 5.6 creates new InnoDB statistic tables (slave_master_info, mysql/slave_relay_log_info, innodb_index_stats, innodb_table_stats, and slave_worker_info) and adds them to the installation directory (basedir) of MySQL, you might encounter a conflict with the innodb_data_file_path = ibdata1:2000M;ibdata2:10M:autoextend option contained in the “my.cnf” file. The file_path option places the InnoDB files one directory level higher than the basedir, which can cause the following error to appear in the MySQL error log:Until you address this error, the plug-in cannot browse the main MySQL database, and the following error appears: "Failed to fetch row from query result: showtable status like 'innodb\_index\_stats'"Because this option originated from a recommended sample “my.cnf” file for an earlier version of MySQL, this issue is likely to occur on upgrades or for new installs that have retained the earlier version of the “my.cnf” file. Dell recommends that you do not use the file_path option on new installations and that you move the ibdata files to basedir for upgrades. For assistance, contact MySQL Support. (22367)Starting with NetVault Backup 8.6, a new build type named “LinuxX86Pure64” has been added, while the pure 32-bit Linux version has been retired. To understand the impact of this change, review the following:
• Hybrid 32/64-bit Build – The hybrid 32/64-bit build has been retained. However, the platform type has been renamed from “LinuxX8664” to “LinuxX86Hybrid.” This build functions as the standard build for Linux users who do not have a pure 64-bit-only requirement. This build lets you upgrade from pure 32-bit as well as from hybrid builds of NetVault Backup.The LinuxX86Hybrid build retains binary compatibility with all previous versions of plug-ins, including those marked as 32-bit and those designated 64-bit. Additionally, this build will work on 32-bit systems that do not have 64-bit capability.
• Pure 64-bit Build – A new type of build named “LinuxX86Pure64” has been introduced for pure 64-bit Linux distributions. If you have a specific reason that you cannot use any 32-bit components (for example, you are using a Linux distribution that does not run 32-bit code), use this type. Note that you cannot use this new type to upgrade existing NetVault Backup installations. You must remove the existing version and install the pure 64-bit version separately. To reduce confusion, warning messages have been added to both the upgrade and installation packages to ensure that you understand that they are not compatible.
