[Zope-dev] Help! Getting there, I hope ...
Right, many thanks to those who have offered advice. I'm conscious that as I've drifted from a coding topic then I'm probably in the wrong mailing list, but everyone has been very patient up to now and I'm hoping that a fix is in sight! :) I have done a backup of the Dats.fs file (took three days!). I have used fsdump and fstest to produce listings about my Data.fs file - fsdump produced a 2.67GB textfile! I have tracked down the first entry that I believe begins all the deletes: tid=0367c03fc4325022 time=2006-08-26 08:31:45.983563 offset=749481328632 user= admin description=/library/reference/manage_delObjects If I'm right ... does that mean if I trim the Data.fs file to 749481328632 bytes long and start Zope off again, that the files should be restored? If so, does anyone know of a good way of trimming such a large binary file down to a specific size? I'm using Suse Linux as a server.

[Zope-dev] Help! Need to extract files out of Data.fs!
Hiya, My company has been using a Zope server to store some reference material, but it has grown beyond belief, and I need to extract all the collected files (about 1.3 terabytes!) from the Data.fs into distinct files onto a different server. Unfortunately, I've run into some problems. Firstly, the FTP transfer process seems to be extremely slow, and if I try and transfer too large or deep a folder structure in one go then things grind to a halt. To beat this I've been carefully recreating the folder structure manually, and copying things in easier-to-digest chunks. Unfortunately, because I was a bit rushed over the weekend I have accidentally deleted about 130,000 files! I've tried going through the Undo procedure, but the idea of manually ticking 130,000 boxes (in pages of 20) and undoing them fills me with dread. So ... Please please /please/ does anyone happen to have the file format for the Data.fs file so that I could write a C program to extract and recreate the files and folders to another server? Or has anyone written such a program already? If so, I'll happily have your children if you can help me out! As it stands, I'm going to have to break it to the librarian (the poor man who has been collating all the reference material for the last six months) that I've lost half of his work, and blaming it on the poor FTP client in Windows seems a bit lame! If it helps: I'm running Zope 2.9.2 on a SuSE Linux box. I have full access to the Linux box ... and a large hammer, if I need it! :( Help! Many thanks in advance, Kris (considering giving up this computing job and going to live in a cave somewhere). ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

Hmm, this is something I don't understand. You deleted 130,000 files in individual transactions? If you deleted the 130,000 files in one big transaction, all you have to do is undo this one transaction. That is, of course, provided that any subsequent transaction you made after deleting the files won't cause inconsistencies and potentially prevent the undo. Perhaps the Windows FTP client chooses to scan through the folder structure itself and individually delete each file? I'm certainly looking at 130,000 entries, anyway. I'd be much happier if I only had to undo one transaction! :( Please please /please/ does anyone happen to have the file format for the Data.fs file so that I could write a C program to extract and recreate the files and folders to another server?

No need for a C program. The ZODB is a Python library, you can use Python to get at your data. The simplest way is to start the Zope debug shell via bin/zopectl debug. You will then have access to the root object in the interpreter prompt and can poke at your objects, including their history. Writing a script and running it via bin/zopectl run shouldn't be a big problem after that. I'd better start reading my Python book, then ... Cheers!

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