Description

The rtcpio command allows operators to backup and restore user files while denying the operators access to administrative files. The rtcpio command calls the tcpio command, restricting the level range of files to be backed up and restored.

If the user does not specify a level range with the -X option, rtcpio calls tcpio with the range USER_PUBLIC,USER_LOGIN specified as the default arguments to the -X option.

If the user specifies a level range with the -X option, the specified range is compared to the allowed range. If the specified range is not within the allowed range, an error message is displayed and no files are backed up or restored. If the specified range is within the allowed range, rtcpio calls tcpio, passing on the arguments to the -X option unchanged.

All other options and arguments specified by the user are passed on unchanged to tcpio, whether or not -X is specified.

The full description of the -X option is:

-X low_level,high_level: Extract only files with MAC level between low_level and high_level, inclusive. high_level must dominate low_level. In addition, the range specified must be within the permitted range; low_level must dominate USER_PUBLIC and high_level must be dominated by USER_LOGIN. LIDs, aliases, or fully qualified level names may be used to specify low_level and high_level. Only valid names or aliases may be used; a LID may be used even if it has been deleted.

All other options are passed unchanged to tcpio. See the tcpio(1) manual page for a full description of these options.
