## PreserveKeysEncoder doesn't encode parameter keys (which is standard Faraday behaviour).
## Usage:
## Faraday.new(url, request: { params_encoder: PreserveKeysEncoder.new })
## Modes:
##  :nested { '$product_id' =>' [10,20,30] } becomes $product_id[1]=10&$product_id[1]=20&$product_id[1]=30
##  :flat and $product_id=10&$product_id=20&$product_id=30 in :flat mode
class Faraday::PreserveKeysEncoder
  MODES = [:nested, :flat]

  delegate :decode, :escape, to: :super_encoder, allow_nil: true

1. ssh in to your Synology
2. $ vi /root/.profile
3. prepend /opt/bin:/opt/sbin: to PATH so it looks like PATH=/opt/bin:/opt/sbin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/syno/sbin:/usr/syno/bin:/usr/local/sbin:/usr/local/bin
   replace the standard rdiff packages with symlinks:
4. $ ln -s /opt/bin/rdiff-backup-2.6 /usr/bin/rdiff-backup
5. $ ln -s /opt/bin/rdiff-backup-statistics-2.6 /usr/bin/rdiff-backup-statistics
