Central backup management
I'am using backblaze B2 for backups. There is multiple servers and my goal would be to find unified central backup software from where I can control backup process. Duplicati does not fit my needs as it requires first upload to central server and than to B2.
Is there any solution which do this:
Server A --> Backup centrale (acts like proxy, GUI, allows restore of backups) --> B2.
It is hard to describe exactly what I need but maybe someone will understand.
P.S. Free and open source.
