As the system is setup to boot via DHCP, just give it a new name. I choose UniMatrixOne

sudo bash
aptitude update
aptitude safe-upgrade
aptitude clean
reboot

I install my normal tool set and the part for borgbackup

aptitude install vim-nox htop screen tcpdump tshark iotop lvm2 rsync \
python3 python3-dev python3-pip python-virtualenv \
libssl-dev openssl \
libacl1-dev libacl1 \
liblz4-dev liblz4-1 \
build-essential
pip3 install borgbackup

I use borg backup on an external 3.5″ disk, which is hooked via SATA2USB Adapter.
To setup the backup disk I use lvm:

# I assume the disk is at /dev/sdb
# Add one primary partition and give it all the space
# as ext2
fdisk /dev/sdb
# Create the physical volume
pvcreate /dev/sdb1
# Create the volume group
vgcreate vg_backup /dev/sb1
# Create the logical volume
lvcreate -n v_backup -l 100%FREE vg_backup
# Create filesystem
mkfs.ext4 -m0 /dev/mapper/vg_backup-lv_backup
mkdir /backup
mount /dev/mapper/vg_backup-lv_backup /backup

And initialize the borg backup

/usr/local/sbin/borg init -e repokey /backup/`hostname`

After installing this /usr/local/sbin/makeLocalBackup.sh script

#!/bin/bash
if [ ! -d /backup/`hostname` ]
then
echo "Mounting target /backup/"
/sbin/vgchange -a y vg_backup
mount /dev/mapper/vg_backup-lv_backup /backup
echo "done"
fi

if [ -d /backup/`hostname` ]
then
/usr/local/bin/borg create -C zlib,9 -x /backup/{hostname}::{now:%Y%m%d-%H%M} / /boot
/usr/local/bin/borg prune --keep-hourly 6 --keep-daily 7 --keep-weekly 4 --keep-monthly 6 /backup/{hostname}
else 
echo "Backup of `hostname` (/, /boot) failed as target was not mounted"
exit 1
fi

and this /usr/local/sbin/showLocalBackup.sh

#!/bin/bash

if [ ! -d /backup/`hostname` ]
then
/sbin/vgchange -a y vg_backup
mount /dev/mapper/vg_backup-lv_backup /backup
fi

if [ -d /backup/`hostname` ]
then
echo "/backup/`hostname`"
/usr/local/bin/borg list /backup/{hostname}
/usr/local/bin/borg info /backup/{hostname}::`/usr/local/bin/borg list /backup/{hostname}|tail -n1|cut -d" " -f1`
du -sch /backup/`hostname`
else
echo "/backup/`hostname` not mounted"
exit 1
fi

We need to check this once a week with this script:

#!/bin/bash
if [ ! -d /backup/`hostname` ]
then
echo "Mounting target /backup/"
/sbin/vgchange -a y vg_backup
mount /dev/mapper/vg_backup-lv_backup /backup
echo "done"
fi

if [ -d /backup/`hostname` ]
then
/usr/local/bin/borg check /backup/{hostname}
else 
echo "Check of Backup of `hostname` failed as target was not mounted"
exit 1
fi

I can add it to the cron system. Voila backup done.

chmod 700 /usr/local/sbin/????LocalBackup.sh
echo "0 * * * * root /usr/local/sbin/makeLocalBackup.sh" >/etc/cron.d/makeLocalBackup
echo '30 0 * * 0 root /usr/local/sbin/checkLocalBackup.sh' >/etc/cron.d/checkLocalBackup

I added the openvpn package and installed my certs.

I also install exim4 and mutt to do basic emailing with forwarding all root mail to my personal account.

aptitude install exim4 mutt
dpkg-reconfigure exim4-config

Next step is to install the SNMPd and setting it up:

aptitude install snmpd
 cat <<EOM >/etc/snmp/snmpd.conf
> rocommunity PleaseSetYourOwn
> sysLocation UniMatrixOne
> sysContact  info@linuxpinguin.de
> disk /       5%
> disk /backup 5%
> disk /boot   5%
> EOM
systemctl restart snmpd
systemctl enable snmpd
