You need a “remote” server where you can write files using ssh/sftp. My remote is a NethServer.
The cloud backup tool/format is duplicity like the standard backup, so I used a full backup I had to “seed” the remote location.
Steps:
- copy backup to usb disk
- drive to remote and cp backup to local hard disk
- add cloud backup scirpt
Steps 1 and 2 can be omitted but the time for the first full backup can be long
While looking at my notes, after having evaluated obnam and attic, I feel that duplicity is not the right tool for this kind of backup and this configuration is complex and error-prone.
I’ll send you the script and listen to your comments, but I think I will abandon this project in favor of attic.
