But I'm filing a bug for paperwork purposes and for Ubuntu SRUs. [Impact] When restarting a backup, duplicity may accidentally skip the first 65k chunk of one of the source files. This means that when it is restored, it will be incomplete/corrupted, resulting in data loss. [Test Case] Download and install the 'test1.sh' file attached to this bug report, and run it like 'sh test1.sh'. If it prints the following line, the bug is present: Binary files /tmp/source/newfile and /tmp/restore/newfile differ Or, follow these manual steps: mkdir /tmp/source dd if=/dev/urandom of=/tmp/source/bigfile bs=1024 count=5000 # This next command will intentionally fail after the second volume! duplicity full /tmp/source file:///tmp/backup --vol 1 --fail 2 --no-encryption mv /tmp/source/bigfile /tmp/source/newfile duplicity full /tmp/source file:///tmp/backup --no-encryption duplicity restore file:///tmp/backup /tmp/restore --no-encryption # This next line will say the files differ if the bug is present diff /tmp/source/newfile /tmp/restore/newfile [Regression Potential] It's a relatively small patch, only affecting the specific case of restarting a backup when the file we were in the middle of is no longer there. I'd say minor regression potential.
