 ====== Server: Backup ======
-There are many ways to backup your server. As NC-AIO already has Borg, you may use Borg for a complete Backup of your system.
+There are many ways to backup your server. As NC-AIO already has Borg, you may use Borg for a complete Backup of your system. The docs can be found here: [[https://borgbackup.readthedocs.io/en/stable/|https://borgbackup.readthedocs.io/en/stable/]]
+You need to perform everything as root. So login as root somehow (maybe use ''sudo -i'')
+===== Create Borg Repository =====
+First, create the Directories:
+  * /backup (should already be there by NC-AIO)
+  * /backup/borg/root
+Please refer to the Documentations of Borg found at [[https://borgbackup.readthedocs.io/en/stable/usage/init.html|https://borgbackup.readthedocs.io/en/stable/usage/init.html]] to create a Repository. You can also use some graphical tool like vorta for this - i did, while it will help to setup borg.
+For me, i chose the location ''/backup/borg/root''  as repository. I included the key, so that i only needed a new passphrase to access the repository:
+<code>
+borg init --encryption repokey-blake2 /backup/borg/root
+</code>
+===== Setup a Script =====
+Create the Directory /root/backup and add a new file ''named borg_backup_root.sh''  there with the contents:
+<file>
+#!/bin/bash
+# Make Borg Backup of Root and all what is needed for Base-System
+cd /root/backup
+#Vars
+export BORG_PASSPHRASE='yoursecretpassphrase'
+ARCHIVNAME="backup-$(date '+%Y%m%d_%H%M%S')"
+REPONAME="/backup/borg/root"
+echo "Starting Backup of Root with Borg"
+#This will create a btrfs readonly snapshot of root in the directory /root_snapshot
+/sbin/btrfs subvolume snapshot -r / /root_snapshot
+echo "Creating Archive ${ARCHIVNAME} in ${REPONAME}..."
+/usr/bin/borg create --warning --show-version --list --filter=AM --show-rc -s -C lz4 --exclude-from /root/backup/excludelist ${REPONAME}::${ARCHIVNAME} /root_snapshot /boot/grub2 /i386-pc /boot/grub2/x86_64-efi /opt /root /srv /tmp /usr/local /var /boot/efi /home
+RETURNCODE=$?
+/sbin/btrfs subvolume delete /root_snapshot
+if [ ${RETURNCODE} -ne 0 ]; then
+ echo "Some ERROR with Borg. Stopping execution."
+ exit ${RETURNCODE}
+fi
+echo "Pruning Archives"
+/usr/bin/borg prune --show-rc --warning --progress --keep-hourly 2 --keep-daily 7 --keep-weekly 4 --keep-monthly 6 --keep-yearly 2 -a pcserver2023-* --keep-within 10H ${REPONAME}
+echo "Checking this Archive (${ARCHIVNAME})"
+/usr/bin/borg check --show-rc ${REPONAME}::${ARCHIVNAME}
+echo "Done Backup root"
+</file>
+Second, add n new File named ''excludelist''  and put in e.g:
+<file>
+#This list was created by Vorta as root (manually copying preview of exlcudes)
+#
+# custom added rules
+/home/docker/nextcloud_data/

+===== Cron- Job =====
+To setup a cron, add a new File named borg_backup_root_cron.sh with content:
+<file>
+#!/bin/bash
+# Execute Borg Backup with cron
+cd /root/backup
+./borg_backup_root.sh> $0.log 2>&1
+cat $0.log
+</file>
+And insert this script to crontab with crontab -e:
+<file>
+1 * * * /root/backup/borg_backup_root_cron.sh
+</file>
+Thats it, your Backup will perform on a daily base. You could also do more backups if you like.
