-# ==========
-# Preparations Server
-# ==========
-
-# preparation on the backup server (o26.oopen.de)
-# ===============================================
-#
-# 1. On Backup Server create a user which is used to push the backups to the server
-#  
-#     backup-user:   borg
-#     backup-group:  borg
-#
-#
-# 2 Create a backup repository:
-#
-#  client-identifier: cl-fm
-#
-#     mkdir -p /backup/<client-identifier>
-#
-#
-# 3. Backup user must have full write permissions to the backup repostitories
-#
-#     chown <backup-user>:<backup-group> /data/backup/<client-identifier>
-#
-# 4. Prevent repository directory from being deleted
-#
-#     chattr +i /data/backup/<client-identifier>
-#
-chattr -i "$(dirname "${BORG_REPO}")"
-mkdir -p "${BORG_REPO}"
-chown ${SSH_USER}:${SSH_USER} "${BORG_REPO}"
-chattr +i "$(dirname "${BORG_REPO}")"

-# ==========
-# Preparations Client
-# ==========
-
-
-# preparation on the backup client (cl-fm.oopen.de
-# ================================================
-#
-# 1. Install Borg Backup (on the client) using 'apt install'
-#
-#     apt install -y -t stable-backports borgbackup python3-llfuse
-#
-#
-# 2. Generate a SSH Key (as root without passphrase) to connect to the backup server:
-#
-#     ssh-keygen -t ed25519 -f ~/.ssh/id_ed25519-borg-backup
-#
-#     Note: 
-#        Dont't forget pusching the key to the servers authorized_key file of
-#        the remote backup user
-#
-#  
-# 3. create file /root/.ssh/config ti store ssh connection parameters
-#  
-#     BORG_HOST="o26.oopen.de"
-#     SSH_USER="borg"
-#     SSH_IDENTITY_FILE="/root/.ssh/id_ed25519-borg-backup"
-#  
-#     cat << EOF > /root/.ssh/config
-#     host ${BORG_HOST}
-#        User ${SSH_USER}
-#        IdentityFile ${SSH_IDENTITY_FILE}
-#        StrictHostKeyChecking no
-#        LogLevel FATAL
-#     EOF
-#
-apt install -y -t stable-backports borgbackup python3-llfuse
-ssh-keygen -t ed25519 -f ~/.ssh/id_ed25519-borg-backup
-cat << EOF > /root/.ssh/config
-host ${BORG_HOST}
-   User ${SSH_USER}
-   IdentityFile ${SSH_IDENTITY_FILE}
-   StrictHostKeyChecking no
-   LogLevel FATAL
-EOF
-
-git clone https://git.oopen.de/backup/borg-backup /root/bin/borg-backup
-
-
-# Initialize backup
-# =================
-#
-#     export SSH_USER="borg"
-#     export BORG_HOST="o26.oopen.de"
-#     export SSH_PORT="22"
-#     export BORG_PASSPHRASE="wweK/m.xV-g3oI-7WM/pejTP"
-#     
-#     export BORG_REPO="/data/backup/cl-fm"
-#
-#     borg init --encryption=repokey ssh://${SSH_USER}@${BORG_HOST}:${SSH_PORT}${BACKUP_REPOSITORY}
-#
-#  Outpu of of borg initializing was:
-#
-#     By default repositories initialized with this version will produce security
-#     errors if written to with an older version (up to and including Borg 1.0.8).
-#
-#     If you want to use these older versions, you can disable the check by running:
-#      borg upgrade --disable-tam ssh://borg@o26.oopen.de:22//data/backup/cl-fm
-#
-#     See https://borgbackup.readthedocs.io/en/stable/changes.html#pre-1-0-9-manifest-spoofing-vulnerability 
-#     for details about the security implications.
-#
-#     IMPORTANT: you will need both KEY AND PASSPHRASE to access this repo!
-#     If you used a repokey mode, the key is stored in the repo, but you should back it up separately.
-#     Use "borg key export" to export the key, optionally in printable format.
-#     Write down the passphrase. Store both at safe place(s).
-#     
-borg init --encryption=repokey ssh://${SSH_USER}@${BORG_HOST}:${SSH_PORT}${BORG_REPO}
