muchas gratias  ... yup, data is back :)

hmm ... don't know who decided to use the wiki for the arbitration case
filings
but the wiki has been established to be the central repository for
arbitration handling and filing.

In the meanwhile, we've installed a "backup" for the email traffic
related to arbitration, but this means only, that the emails sent
by casemanagers, arbitrators and other arbitration participients
are copied to a mailbox archive.

The complete index and summary about an arbitration case that is
the wiki file has to be recovered from all these emails from
an individual case.

Deliberations and discoverys are mostly not subject of any emails,
its collected in the wiki file public or private part.

Before one year, there was a project to search / deploy an arbitration
handling software, but this only moves the backup problem from one
server to another ...

The wiki but not only includes the arbitration files, also the wiki
includes procedures, manuals, and other essential material we have
in short: the wiki is CAcert's knowledgebase and history database
for many procedures

The wikis own revisioning system is helpful, but not helpful
in a disaster issue

So the current harddisk corruption gives us some hint
to rethink about a backup strategy

To recover lost parts of the wiki is probably not a so
critical issue as the disaster recovery process of
the critical system. So recovery of lost wiki pages,
if it needs eg 3 days or a week to recover a lost page
isn't that a problem, but it should be possible to recover
a page in principle
