Bug Description

We have the 103 GB data in volume and trying to take the backup, but it is taking too much time and failed to take the backup of entire data.

duplicity 0.8.03
Data size 103 GB
endpoint is s3.us-south.objectstorage.softlayer.net
python version 3.7.3

cat /etc/os-release
NAME="Alpine Linux"
ID=alpine
VERSION_ID=3.10.1

Note : one of our customer failed to take the backup of 130GB size.

How large is the sigtar file? Do you have any logs?

It's an old one. A couple of workarounds may help:
- split the backup along directories
- use --max-blocksize=8192 or more (multiple of 512)
