Re: [Zope] Restore files from Data.fs.tr0 SOLVED
This simple script and diff and manual changes against appropriate files. #!/var/zope/python/bin/python f = open(Data.fs.tr0, r+ab) c = f.read() s='__name__q' a = c.split(s) i = 0 print(len(a)) for polozka in a: i = i + 1 fn = 'vystup_' + str(i) x = open(fn,ab) x.write(polozka) x.close() f.close() Lucky that it was no much of filenames. Select both files in Total Commander, then File - Diff - uncheck binary and check again - Edit, helps a lot. For bigger truncated slices it could be better to do it with filename support etc. Regards, JL. ___ Zope maillist - Zope@zope.org https://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope-dev )

Re: [Zope] Restore files from Data.fs.tr0
Hi, I use the following steps to get objects from a corrupted Data.fs. You can apply some guesses regarding the dates. 1. Make another Zope instance, with same products 2. Copy the real Data.fs into this temporary zope instance 3. Start zopedebug: $:/path-to-zope/bin/zopectl debug. Run these commands: import ZODB.DB, ZODB.FileStorage, cPickle from ZODB.TimeStamp import TimeStamp from OFS import ObjectManager date_tuple = (2009,8,23,23,17,06) #date when data was safe special_date = TimeStamp(*date_tuple) #make date into special format filename=’/var/local/zopetest/var/db.fs’ #path to Zope’s Data.fs (zope instance have to be stopped atm) storage = ZODB.FileStorage.FileStorage(filename, read_only=1,stop=`special_date`) #wait few minutes, until it opens Data.fs DB = ZODB.DB(storage) #mount database conn = DB.open() #open database root = conn.root()['Application'] folder = getattr(root, ‘myfolder’) #the parent containing the folder with the objects you want to recover folder.manage_exportObject(id=’mycontent’,download=0) Hope it helps.

Re: [Zope] Restore files from Data.fs.tr0
Hi, thanks for assistance, but this solution make export of data up to specified date in Undo history, instead of rescuing things from data.fs.tr0. Is it possible to rescue data from data.fs.tr0, please?
