## Motivation
OVH provides a cheap way for longterm storing backup data, the Public Cloud Archive (PCA). As this is for write-once data (cold data store), it needs to be used together with a little bit more expensive hot data store for meta data when used for sequential backups. The backup solution [duplicity](https://duplicity.gitlab.io/duplicity-web/) is capable of using such multi backends. [backupninja](https://0xacab.org/liberate/backupninja) provides a nice solution for a standardized configuration of duplicity and running it automatically.
