Data are not persistent on disk

Hi,
I have emoncms installed on my own host, Debian7+Apache2.2 emoncs low-write 9.7.2 | 2016.07.04

I updated my installation from 9.0 to this version last Friday (2016/7/29) and since that date, seem file into /var/lib/phpfiwa/ are not updated. For mistake I Flush Redis on Administration Page, and lost all data since 29 July.
I have not a SD like disk, so don’t care how many access emoncms do on this.
I would like to restore persistence on disk of all data.

How can I do this?

Thanks

Marco
