My install is multisite: one main site and one sub-site. I activated the plugin on the network. Then, I use the plugin (settings, schedule, etc) only on the main site, am I right ? That's the way I do it on another multisite of mine and it works perfectly.
I must have made a mistake when setting up the plugin (a few days ago)...
On the "General settings" page (main site), I see "Encryption type: None (not recommanded)". I have an encryption key though. When I click "Show", it shows it.
The thing is that I don't seem to be able to set the right Encryption type. A permanent overlighted message says "Encryption details CANNOT be changed because Online Backup is currently active.
Online Backup is incremental - that is, only changes made between backups are actually sent to the online vault - and so the encryption details used for each backup must remain the same."
So my questions :
1) Is the "Encryption type: None" a problem ?
2) If so, is there a way to change it?
Additional info: on the subsite, the Encryption is the right type (AES128) but that's not where I schedule my backups, so I don't know if it's useful...
