Hello,
I'd like assist you with this task. In case your Odoo srvr is installed with default configuration it uses Postgresql I'm enough experienced with.
What I will need is
1. Either access to the srvr or credentials to login with appropriate rights from my ip (more securely, btw). Please connect me in case you need any assistance with these things, - I will explain more and show you.
2. Access to a srorage the backup files fill be places in.
Thanks in advance,
Sergii
