• To have the permission Drives administrator

Under certain circumstances (ransomware, accidental deletion of huge number of files) it can be useful to restore a drive to a previous date, thus cancelling all the changes made after this date.

Start by clicking on Lena's icon in your task bar and then click on :

Then click on the drives management icon in the left-side menu ① then right click on a drive → Reset drive to a previous date ② :

Chose the date and time ① to which the drive should be restored to in the window appearing on your screen. A list of all the changes resulting from the rollback will then be shown ②. Click on Reset drive to continue.

Since the resulting changes are not reversible, you will be asked to type a confirmation message in the next window ① (validate by clicking on Okay ②).
