15.9 Single-File Backup Options

These options are associated with single-file backups. You use them in combination with the mysqlbackup commands backup-to-image, image-to-backup-dir, backup-dir-to-image, copy-back-and-apply-log, list-image, and extract. For usage examples, see Section 4.3.1, “Making a Single-File Backup”.

• --backup-image=IMAGE

  See description of the option in Section 15.4, “Backup Repository Options”

• --src-entry=PATH

  Command-Line Format	--src-entry=PATH
  Permitted Values	Type	path name

  Identifies a file or directory to extract from a single-file backup. This option is used with the extract command. If the argument is a directory, all its files and subdirectory contents are extracted. No pattern matching expression is allowed for the argument. Optionally, you can also specify the --dst-entry option to extract the file or directory in a location different from its original path name.

  For example: src-entry=meta/comments.txt extracts only one file, comments.txt, while src-entry=meta extracts the entire directory tree for the meta subdirectory.

  Default: All entries are extracted.

  Note

  The option is currently not supported for the extract command for cloud backups, which can only be extracted in full.

• --dst-entry=PATH

  Command-Line Format	--dst-entry=PATH
  Permitted Values	Type	path name

  Used with single-file backups to extract a single file or directory to a user-specified path. Use of this option requires specifying the --src-entry option. This option specifies the destination path for the entry selected from the backup image by --src-entry. The entry could point to a single file or single directory. For example, to retrieve the comments file from a backup image and store it as /tmp/my-comments.txt, use a command like the following:

  mysqlbackup --src-entry=meta/comments.txt \
    --dst-entry=/tmp/my-comments.txt \
    --backup-image=/var/myimage.bki  extract

  Similarly, to extract all the contents of the meta directory in a single-file backup as /data/my-meta, use a command like the following:

  mysqlbackup --src-entry=meta \
    --dst-entry=/data/my-meta \
    --backup-image=/var/myimage.bki  extract

  The specified path is a simple path name without any wildcard expansion or regular expressions.

  Default: By default, original pathnames are used to create files in the local file system.

• --sbt-database-name=NAME

  Command-Line Format	--sbt-database-name=NAME
  Permitted Values	Type	string
  	Default	MySQL

  For tape backups, this option can be used as a hint to the Media Management Software (MMS) for the selection of media and policies. This name has nothing to do with MySQL database names. It is a term used by the MMS. See Section 4.3.1.2, “Backing Up to Tape” for usage details.

• --sbt-lib-path=PATH

  Command-Line Format	--sbt-lib-path=PATH
  Permitted Values	Type	file name

  Path name of the SBT library used by the software that manages tape backups. If this is not specified, operating system-specific search methods are used to locate libobk.so (UNIX) or orasbt.dll (Windows). See Section 4.3.1.2, “Backing Up to Tape” for usage details.

• --sbt-environment=VAR=value,...

  Command-Line Format	--sbt-environment=VAR1=value1[,VAR2=value2[,...]] SBT API provider)
  Permitted Values	Type	string

  Passes product-specific environment variables to Oracle Secure Backup or another SBT-compliant backup management product, as an alternative to setting and unsetting environment variables before and after each mysqlbackup invocation.

  The parameter to this option is a comma-separated list of key-value pairs, using syntax similar to that of the RMAN tool for the Oracle Database. For example, --sbt-environment=VAR1=val1,VAR2=val2,VAR3=val3.

  Consult the documentation for your backup management product to see which of its features can be controlled through environment variables. For example, the Oracle Secure Backup product defines environment variables such as OB_MEDIA_FAMILY, OB_DEVICE, and OB_RESOURCE_WAIT_TIME. You might set such variables with the mysqlbackup by specifying an option such as --sbt-environment="OB_MEDIA_FAMILY=my_mf,OB_DEVICE=my_tape".

  If the argument string contains any whitespace or special characters recognized by the command shell, enclose the entire argument string in quotation marks. To escape an equals sign or comma, use the \ character. For example, --sbt-environment="VAR1=multiple words,VAR2=<angle_brackets>,VAR3=2+2\=4".

• --disable-manifest

  Disable generation of manifest files for a backup operation, which are backup_create.xml and backup_content.xml present in the meta subdirectory.
