[Duplicity-talk] SSLError: The write operation timed out (wouldn't retry)

[Teresa e Junior]

Hello!

Yesterday, duplicity backup with WebDAV failed twice. It said that "The
write operation timed out", but I can see it has tried only once. I
believe Duplicity should have tried uploading the volume again instead
of failing and forcing me to restart everything. Am I doing anything
wrong? In the manual I couldn't find any --retry option or similar.

Running duplicity 0.6.18-3 on Debian Stable.

Here is the code I run:
LC_ALL=C duplicity --verbosity info --archive-dir=$root/         \
    --include-globbing-filelist $root/files.log --exclude '**' / \
    --volsize 5 --asynchronous-upload                            \
webdavs://address@hidden/duplicity/

And here is the part that failed:
A tmp/filename 01
A tmp/filename 02
A tmp/filename 03
