MySQL Enterprise Backup User's Guide (Version 3.11.1)
Tape drives are affordable, high-capacity storage devices for backup data. The MySQL Enterprise Backup product can interface with media management software (MMS) such as Oracle Secure Backup (OSB) to drive MySQL backup and restore jobs. The media management software must support Version 2 or higher of the System Backup to Tape (SBT) interface.
On the MySQL Enterprise Backup side, you run the backup job as a single-file backup
using the --backup-image
parameter,
with the prefix sbt:
in front of the filename,
and optionally pass other --sbt-*
parameters to
the mysqlbackup command to control various
aspects of the SBT processing. The --sbt-*
options are listed in
Section 5.1.10, “Single-File Backup Options”.
On the OSB side, you can schedule MySQL Enterprise Backup jobs by specifying a
configurable command that calls mysqlbackup.
You control OSB features such as encryption by defining a
“storage selector” that applies those features to a
particular backup, and passing the name of the storage selector to
OSB using the MySQL Enterprise Backup parameter
--sbt-database-name=
.
storage_selector
To back up MySQL data to tape:
Specify the
--backup-image=sbt:
parameter of the mysqlbackup command to
uniquely identify the backup data. The name
sbt:
prefix sends the backup data to the MMS rather than a local
file, and the remainder of the argument value is used as the
unique backup name within the MMS.
Specify the --sbt-database-name
parameter of
the mysqlbackup command to enable the OSB
operator to configure a storage selector for backups from this
MySQL source. (This parameter refers to a “storage
selector” defined by the OSB operator, not to any MySQL
database name.) By default, mysqlbackup
supplies a value of MySQL
for this MMS
parameter. The argument to this option is limited to 8 bytes.
If you have multiple media management programs installed, to
select the specific SBT library to use, specify the
--sbt-lib-path
parameter of the
mysqlbackup command. If you do not specify
the --sbt-lib-path
parameter,
mysqlbackup uses the normal operating
system paths and environment variables to locate the SBT
library, which is named libobk.so
on Linux
and Unix systems and ORASBT.DLL
on Windows
systems. When you specify --sbt-lib-path
, you
can use a different filename for the library in addition to
specifying the path.
Specify any other product-specific settings that are normally
controlled by environment variables using the
--sbt-environment
option.
To restore MySQL data from tape:
Specify the
--backup-image=sbt:
parameter of the mysqlbackup command as
part of the restore operation. Use the same
name
name
value as during the original
backup. This single parameter retrieves the appropriate data
from the appropriate tape device.
Optionally use the --sbt-lib-path
option,
using the same values as for the backup operation.
Specify any other product-specific settings that are normally
controlled by environment variables using the
--sbt-environment
option.
