There is an option in the control panel Wouldn't this remove all the deleted files? Or is compression different to packing?

One more thing, what does the disk where the Data.fs resides look like? On Mon, 28 Aug 2006, Dennis Allison wrote: > > Kris, > > I assume you have a backup of the Data.fs.

Re: [Zope-dev] Help! Need to extract files out of Data.fs!
Kris, I assume you have a backup of the Data.fs. If you do, nothing is really lost. Have you compressed the Data.fs? There is an option in the control panel to do this. I can be run on a live machine, but you may not want to do so given the size of stuff. I'd do it on a quiet machine. This will remove any cruft you have in the Data.fs and will improve your speed of access somewhat, Things are probably slow because of swapping. Reducing the size of Data.fs may speed things up. Take a look at the documentation for the ZODB (Google is your friend). You could write a program in Python to simply open the ZODB and extract the files you need. It might save a bit of overhead. Remember 1.3TB is a large file and is going to take some time to process no matter what.
