Backup Bouncer is here to help keep the ugly backup tools out of the club. Its a command-line-based test suite that makes it easy to find out how bad (or good, if youre lucky) your backup software is. It aims to be a comprehensive test for preservation of all OS X file metadata.
The initial release tests for preservation of:
Basic permissions, ownership, and timestamps
Ownership of symbolic links
Finder creation date
Extended attributes (on files, directories, and symbolic links)
Access Control Lists (on files, directories, and symbolic links)
Combinations of the above
Backup Bouncer can do many things to make testing easy for you. It can:
Create test volumes
Populate them with interesting files
Run a test suite of popular (and not-so-popular) command-line copiers, including cp, rsync, tar, ditto, pax, and xar
Verify the results of a copy, either from its own test suite or your favorite command-line or graphical tool
It also includes an autopilot script to make test volumes, populate them, run the test suite, and verify the results. For a more detailed description and some sample output, see my blog entry on the initial release of Backup Bouncer.
Snow Leopard Note: Backup Bouncer 0.2.0 and higher work properly on Snow Leopard. However, as of OS X 10.6.1, the rsync that Apple shipped has a bug that causes it to hang on the 90-fifo test. You can use Control-C to interrupt the test or move it out of the tests.d directory so it is skipped.
OS X 10.4 - 10.7
