By default, the dump command now preserves ACLs during a backup operation. When archiving a file or file system with tar, use the --acls option to preserve ACLs. Similarly, when using cp to copy files with ACLs, include the --preserve=mode option to ensure that ACLs are copied across too. In addition, the -a option (equivalent to -dR --preserve=all) of cp also preserves ACLs during a backup along with other information such as timestamps, SELinux contexts, and the like. For more information about dump, tar, or cp, refer to their respective man pages.

The star utility is similar to the tar utility in that it can be used to generate archives of files; however, some of its options are different. Refer to Table 16.1, “Command Line Options for star” for a listing of more commonly used options. For all available options, refer to man star. The star package is required to use this utility.
