Class: SafeDb::Obliterate

Inherits:
Controller show all
Defined in:
lib/controller/db/obliterate.rb

Overview

Obliterate the entire safe database by removing a number of folders. This is a drastic action especially as it will terminate all safe sessions on the machine no matter which shell is being used.

This action is recoverable in two ways. The first is a “safe pull” if using a remote repository like git. The second is manual restoration of the obliterated folder which is saved in the safedb-backup-crypts folder.
