[FEATURE] Integrate WAL archive

[scwall]

Hello,

I'm currently looking for a backup system for critical data, where the loss of a few hours could be particularly problematic. On discovering your project, which I find very interesting for simplifying backups, I wondered whether it wouldn't be a good idea to integrate an option such as WAL-G. This would provide a more complete backup, including transaction files ?

Thank's in advance for response
