To save the partition image outside of Tails, you need an external hard disk with as much free space as the size of your Persistent Storage, usually 8 GB less than your TailsUSB stick. You can also use another USB stick of the same size as your TailsUSB stick, but writing to a USB stick is usually much slower than writing to a hard disk.
When the hardware of your USB stick is not failing, using the *Disks* utility is the simplest way of creating a partition image of your Persistent Storage.
Plug in the hard disk on which you want to save the partition image of your Persistent Storage. You need as much free space as the size of your Persistent Storage, usually 8 GB less than your TailsUSB stick.
