Some more testing: I installed a virtualenv with python 2.7.12 and duplicity 0.7.09, but the problem still remains.
Then I ran the little test mentioned in https://bugs.python.org/issue27130 which shows that zlib has a problem zipping files > 4Gb: When looking at the timestamps of the comments, it seems this issue was fixed after 2.7.12 came out, so it will probably be in the next release. I am currently running a backup with all files >4Gb excluded to see if that completes OK. --- $ python --version Python 2.7.6 $ python -c "import zlib;zlib.crc32('a'*(1<<31 - 1))" $ python -c "import zlib;zlib.crc32('a'*(1<<31))" Traceback (most recent call last): File "<string>", line 1, in <module> OverflowError: size does not fit in an int --- $ . venv.2.7.12/bin/activate (venv.2.7.12) $ python --version Python 2.7.12 (venv.2.7.12) $ python -c "import zlib;zlib.crc32('a'*(1<<31 - 1))" (venv.2.7.12) $ python -c "import zlib;zlib.crc32('a'*(1<<31))" Traceback (most recent call last): File "<string>", line 1, in <module> OverflowError: size does not fit in an int ** Bug watch added: Python Roundup #27130 http://bugs.python.org/issue27130 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1612554 Title: duplicity backup fails with OverflowError: size does not fit in an int To manage notifications about this bug go to: https://bugs.launchpad.net/duplicity/+bug/1612554/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
