# Explanation

I use two partitions sda1 and sda2. While sda1 is /boot-only, everything else is on sda2.

sda2 is then encrypted via luks which has lvm inside.

/home is on /data.

This way I can easily sync my system files (residing on lvm-void) to it’s backup place (lvm-copy).

Since all the data is on it’s own partition there is no trouble when I have to restore a backup from lvm-copy since /home is not affected.

# Backup

My backups are split into three different categories:

# System

This backup includes a copy of /boot, all files/dirs listed above, luks-headers, the lvm-config, a void package list and a backup of block devices and their ids.

# User

A user backup typically includes all app files (configs and data), user-specific binaries/programs and all documents/downloads/mails/etc.

# Media

Every other data-type, mostly big-data, is included in this backup. Files like pictures, songs, movies and alike will be backed up to this place. This backup normally takes the longest amount of time.
