partitions and slices - basic

[Humberto]

The operating systems Windows and Linux partitions are very simple. The concept is more complicated with BSD.

What is a partition? In short, this is the "cutting" a virtual hard drive (internal or external) into multiple smaller hard drives.

Scores on Windows and GNU / Linux

The only difference between Windows and GNU / Linux is naming scores.

• Windows uses letters (hence a limited number of partitions).
• GNU / Linux uses a combination of letters and numbers but the letters do are actually the type of equipment (HD for an internal hard drive, SD for a SCSI disk). Here, then, to partition limits!

Scores under BSD systems

BSD systems need a partition that they will then cut into slices (tranches).

The partition, in the traditional sense Windows and Linux, includes the BSD operating system.

The BSD operating system is spread over several installments - the slices -. Typically, isolation and / (root), / usr, / var / tmp, / home and swap. Each installment is differentiated by a letter. But naming slices varies between NetBSD, OpenBSD, FreeBSD. Better therefore to relate to this level dedicated to the documentation system to precisely target BSD ;-)

Saving a slice BSD

This system partitioning - partition divided into installment - BSD may seem cumbersome because operating systems BSD does not detect a single partition and no slices BSD.

It will be more difficult to create a system image (ghost image) and / or recover lost data by mistake!

Of course you can keep backups of your personal data by creating a tar.gz archive

To create a system image, rather think the dd command creates a physical copy block by block
