[ltp] Linux on ThinkPad X1 Carbon 2nd Gen: which partitions to keep/backup?

[Nikos Alexandris]

A new TP X1 Carbon 2nd Gen (with a 256GB SSD), contains the following 
partitions:

sda1: ntfs, WINRE_DRV, ~1GB
sda2: fat32, SYSTEM_DRV, ~260MB
sda3: unknown, Microsoft Reserved Partition, ~128MB
sda4: ntfs, Windows8_OS, ~217GB
sda5: ntfs, Lenovo_Recovery, ~14GB
sda6: unknown, Basic data partition, ~7GB


Does anyone know if the "Lenovo_Recovery" partition the most/only 
important one if the machince should be restored to "Factory Setup"?  
There is something related to this at

Thank you, Nikos
