Xtar solves this problem by saving each data and resource forks as two files in the standard TAR container format to preserve all information. During a restore with Xtar on an HFS volume, the resource and finder information will be restored into a valid HFS files containing all information. This prevents data loss and enables you to create a bootable backup disc of Mac OS X. It is also ideal for backing up and restoring files and folders. Xtar is based on GNU tar (version 1.13.25).
