Use Duplicati for Backup to S3 on Ubuntu Server

backup-to-s3.sh

#!/bin/bash
#
# You need Duplicati installed
# First on Ubuntu it uses mono :( unfortunately:
#   apt-get install mono-runtime
# get the latest Duplicati 2.0 - go here--> http://www.duplicati.com/download
#   wget https://updates.duplicati.com/experimental/duplicati_2.0.1.30-1_all.deb
#   sudo dpkg -i duplicati_2.0.1.30-1_all.deb
#
# After install you will have a 'duplicati-cli' which is a script which runs the mono program: Duplicati.CommandLine.exe
# 

# For more info: duplicati-cli help backup  &  duplicati-cli help s3

# backup to an s3 bucket:

BUCKET_NAME="my-backup"
BUCKET_FOLDER="backups"
AWS_SECRET_KEY="xxxxxx-LONGER-ONE:)-xxxxxx"
AWS_ACCESS_KEY="ABCDEFGHXXXXXX"

BACKUP_DIR="backup-this-dir"

duplicati-cli \
  --aws_secret_access_key=\"${AWS_SECRET_KEY}\" \
  --aws_access_key_id=\"${AWS_ACCESS_KEY}\" \
  --s3-ext-signatureversion=4 \
  --use-ssl \
  --s3-location-constraint=us-east-1 \
  backup s3://${BUCKET_NAME}/${BUCKET_FOLDER} ${BACKUP_DIR}

# the   --s3-ext-signatureversion=4  is needed if the bucket is in a newer region.

# ISSUES: There seems to be a problem uploading to us-east-2. I filed a ticket here: https://github.com/duplicati/duplicati/issues/2175
