I haven't tested it with backup bouncer yet but that's the next step. CrashPlan has never failed to restore correctly in my case, including those pesky Eudora files.

Why on earth wouldn't they save timestamps, finder flags, and extended-attrs is confusing. It's not like this adds much overhead to the stored data.

It appears you ran this with the beta version of our service. We launched the service publicly on 4/14/09 (about a month after your test) and added support for resource forks, dates, etc. However, Backblaze is a DATA backup service, not a disk imaging tool, and thus does not keep some of the components you mention. We backup all of the photos, music, documents, etc. for users. Gleb Budman CEO, Backblaze Thanks flo for running the test. It appears you ran this with the beta version of our service.

Impressive! I guess these online backup services are really only focused on preserving data, not metadata. That's a shame, though, since losing basic permissions can cause all kinds of problems. But if you just want to make sure you don't lose your Word and Excel documents I guess this result is OK. Ooh, perfect FAIL! Impressive!

This is backblaze:

Not too good, although I didn’t expect it to pass most tests, because it is not meant for bare metal restore or anything like that (for example it will backup Library but not most other System directories) but I’d say it should at least support xattrs and retain dates etc.
