--compress, -c

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

Decrypts a file encrypted by NDB using the supplied key.

--decrypt-key-from-stdin

Decrypts a file encrypted by NDB using the key supplied from stdin.

--decrypt-password=password

Decrypts a file encrypted by NDB using the password supplied.

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

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

Read given file after global files are read.

--defaults-file

Read default options from given file only.

--defaults-group-suffix

Also read groups with CONCAT(group, suffix).

--detailed-info

Print out file information like --info, but include the file's header and trailer.

Example:

$> ndbxfrm --detailed-info S0.sysfile

--encrypt-block-size=#

Size of input data chunks that are encrypted as a unit. Used with XTS; set to 0 (the default) for CBC mode.

--encrypt-cipher=#

Cipher used for encryption. Set to 1 for CBC mode (the default), or 2 for XTS.

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

When encrypting a file, specifies the number of iterations to use for the encryption key. Requires the --encrypt-password option.

--encrypt-key=key

Encrypts a file using the supplied key.

--encrypt-key-from-stdin

Encrypt a file using the key supplied from stdin.

--encrypt-password=password

Encrypts the backup file using the password supplied by the option. The password must meet the requirements listed here:

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

Encrypts a file using a password supplied from standard input. This is similar to entering a password is entered after invoking mysql --password with no password following the option.

--help, -?

Prints usage information for the program.

--info, -i

Prints the following information about one or more input files:

Example:

$> ndbxfrm -i BACKUP-10-0.5.Data BACKUP-10.5.ctl BACKUP-10.5.log
File=BACKUP-10-0.5.Data, compression=no, encryption=yes
File=BACKUP-10.5.ctl, compression=no, encryption=yes
File=BACKUP-10.5.log, compression=no, encryption=yes

Beginning with NDB 8.0.31, you can also see the file's header and trailer using the --detailed-info option.

--login-path

Read given path from login file.

--no-defaults

Do not read default options from any option file other than login file.

--print-defaults

Print program argument list and exit.

--usage, -?

Synonym for --help.

--version, -V

Prints out version information.
