I've not tried it with more verbosity yet. I did write a simple script
which shows some output, but it requires strace. Example output:
Diskspace used: 1591229 MiB / 1553 GiB
Duplicity volume: 10127
Amount uploaded: 253175 MiB / 247 GiB.
15.91% done, 1306 GiB left to upload of 1553 GiB.
Script:
#!/bin/bash
if [[ -z "$(pgrep strace)" ]]; then
# Attach strace to Duplicity and log writes to /tmp/duplicity.strace
# look for lines like write(6, "Volume 8113:\n StartingPath
"..., 246) = 246
strace -e trace=write -o /tmp/duplicity.strace -p $(pgrep duplicity) &
sleep 5
fi
if [[ -f "/tmp/duplicity.strace" ]]; then
sleep 5
TOTAL_DISK_USED="$(df -BM --total 2>/dev/null| awk '/total/ {print
$3}' | sed -e 's/M//g')"
DUPLICITY_VOL_DONE="$(grep -a -oE 'Volume [0-9]{1,6}'
/tmp/duplicity.strace | grep -a -oE '[0-9]{1,6}' | tail -n 1)"
if [[ -z "${DUPLICITY_VOL_DONE}" ]]; then
echo "Error reading current volume"
exit 1
fi
DUPLICITY_MiB_DONE="$(( ${DUPLICITY_VOL_DONE} * 25 ))"
DUPLICITY_GiB_DONE="$(( ( ${DUPLICITY_VOL_DONE} * 25 ) / 1024))"
MiB_LEFT="$(( ${TOTAL_DISK_USED} - ${DUPLICITY_MiB_DONE} ))"
PERC_DONE="$(awk "BEGIN {printf
\"%.2f\",(${DUPLICITY_MiB_DONE}/${TOTAL_DISK_USED})*100}")"
if [[ -n "${TOTAL_DISK_USED}" ]]; then
echo "Diskspace used: ${TOTAL_DISK_USED} MiB / $((
${TOTAL_DISK_USED} / 1024 )) GiB"
fi
if [[ -n "${DUPLICITY_VOL_DONE}" ]]; then
echo "Duplicity volume: ${DUPLICITY_VOL_DONE}"
fi
if [[ -n "${DUPLICITY_MiB_DONE}" ]]; then
echo -n "Amount uploaded: ${DUPLICITY_MiB_DONE} MiB / "
echo "${DUPLICITY_GiB_DONE} GiB."
fi
echo "${PERC_DONE}% done, $(( ${MiB_LEFT} / 1024 )) GiB left to
upload of $(( ${TOTAL_DISK_USED} / 1024 )) GiB."
echo >/tmp/duplicity.strace
fi
