Whenever you install Kali2 on a new shining PC or reinstall your old faithful workhorse, it'a a good idea to backup all the PC content, not only the "working" directories. Sure enough, someday you may want to restore something you forgot to backup, such as an old /etc/somekeyfile, /opt/product/registrationkey, or the hidden .bitcoin folder containing the private key you need to became rich in 2030.
A good solution (and a good exercise) for a complete backup is to do a Computer Forensics disk image. This approach has some advantages:
- The image is compressed and split, but it can be mounted as-is and its contents accessed with read-only guarantee.
- The backup contains everything, not only your working data. It contains even recently deleted files if you don't zero the free space before the backup (file-carving).
- An EFF disk image contains integrity checks for each block of data, so the disk can be reconstructed from the good parts in case of damage.
- You may always restore your disk content someday, as if nothing happened.
- Nevertheless, it's easy.
