Duplicity 0.7.06 (installed with homebrew)
Python 2.7.10
OSX 10.11.6
Target filesystem: par2+file to /dev/disk5s1 on /Volumes/DupTest (hfs, local, nodev, nosuid, journaled, noowners, mounted by lv)
A full backup works with file:// to both the root disk (hfs, local, journaled) and to /Volumes/DupTest. With par2+file:// it works to the root disk, but *not* to /Volumes/DupTest.
It seems to be the specific combination of par2, file and mounted Volume. It doesn't matter where the data resides that I try to backup, only the target filesystem seems to make a difference.
Here is the log of a failed run:
✔ ~/tmp/duptest$ find test
test
test/1
✔ ~/tmp/duptest$ duplicity full -v9 test par2+file:///Volumes/DupTest/backup
