--compress, -c

使用与压缩 NDB 集群备份相同的方法压缩输入文件，并将输出写入输出文件。要解压未加密的压缩 NDB 备份文件，只需调用 ndbxfrm 并使用压缩文件名和输出文件名（无需任何选项）。Compresses the input file, using the same compression method as is used for compressing NDB Cluster backups, and writes the output to an output file. To decompress a compressed NDB backup file that is not encrypted, it is necessary only to invoke ndbxfrm using the names of the compressed file and an output file (with no options required).

--decrypt-key=key, -K key

使用提供的密钥解密由 NDB 加密的文件。Decrypts a file encrypted by NDB using the supplied key.

--decrypt-key-from-stdin

使用从 stdin 提供的密钥解密由 NDB 加密的文件。Decrypts a file encrypted by NDB using the key supplied from stdin.

--decrypt-password=password

使用提供的密码解密由 NDB 加密的文件。Decrypts a file encrypted by NDB using the password supplied.

--decrypt-password-from-stdin[=TRUE|FALSE]

使用从标准输入提供的密码解密由 NDB 加密的文件。这类似于在调用 mysql 后输入密码，使用 --password 但选项后未跟密码。Decrypts a file encrypted by NDB, using a password supplied from standard input. This is similar to entering a password after invoking mysql --password with no password following the option.

--defaults-extra-file

在读取全局文件之后读取给定文件。Read given file after global files are read.

--defaults-file

仅从指定文件读取默认选项。Read default options from given file only.

--defaults-group-suffix

还可以读取 CONCAT(group, suffix) 组合的组。Also read groups with CONCAT(group, suffix).

--detailed-info

打印文件信息，如 --info，但包括文件的头部和尾部。Print out file information like --info, but include the file's header and trailer.

示例：Example:

$> ndbxfrm --detailed-info S0.sysfile

--encrypt-block-size=#

作为一个单元加密的输入数据块大小。用于 XTS；在 CBC 模式下设为 0（默认值）。Size of input data chunks that are encrypted as a unit. Used with XTS; set to 0 (the default) for CBC mode.

--encrypt-cipher=#

用于加密的密码算法。CBC 模式（默认值）设置为 1，XTS 设置为 2。Cipher used for encryption. Set to 1 for CBC mode (the default), or 2 for XTS.

--encrypt-kdf-iter-count=#, -k #
