I thought that I would back up my data.fs by copyting the entire Linux /var directory to a Windows machine with spare disk space and then creating a ZIP file on the Windows machine. There was a problem on the Linux machine, so I figured there'd be no problem by simply copying the data.fs (via a Samba share) back from Windows -> Linux. It seems that when Zope starts back up, it keeps attempting to deal with the "alien" database and then shuts down. The Same Database File Works Perfectly With A Windows Plone/Zope Installation ------------------------------------------------------------------------------------------------- I installed a Windows version of Plone (with Zope of course) and that same data.fs file works just fine in the Windows environment. Questions: ------------ 1) Am I without hope of ever running the database under Linux again? 2) What is the reason that the database goes from Linux -> Windows OK but not in the other direction? 3) MOST IMPORTANT: Is there a technique I can use to tweak the database file or recover it so that it is Linux-friendly?
