Backups

Server Backups

AllStarLink, Inc uses a per server backup method based on borg.

Installing Borg on Ubuntu 16

the default package that ships with ubuntu 16.04 LTS is borg 1.0 based and we use the latest 1.1 version as it has several security fixes.

Install nessary packages

   apt-get install libacl1-dev python3-dev libssl-dev gcc g++

install pip

   curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
   python3 get-pip.py

Install Borg

   pip3 install borgbackup

Test for proper version

   root:~# borg -V
   borg 1.1.7

   which borg
   /usr/local/bin/borg

Install the scripts

This will install a new ssh key for root that matches the Rsync.net account and place the borg.inc program in the /root/ directory.

   cd /
   tar -xvf /root/borg-root-config.tar 

Edit the borg script

On the Db servers we add a command to dump the database to /var/mysql-backup-current.sql.bz2

Initialize the repo

Copy the export lines to your shell and run then do

   echo $BORG_REPO
   ASLUSER@host.rsync.net:borg/ASL/db-ord

The borg/ASL/db-ord needs to be created on the server

   ssh -t ASLUSER@host.rsync.net mkdir -p borg/ASL/db-ord

now we need to init the repo at that location

   borg init -e keyfile-blake2 -p -v

export the key

   borg key export --paper

Email this output GPG encrypted to the admin team members.

If we lose this key, there is no way to restore the backup. This means if the server dies, we need the paper key record and the passphrase.

Do the first backup

   /root/borg.inc

Check that it's succeed

move borg.inc to cron

   mv /root/borg.inc /srv/borg.sh

edit crontab

edit /etc/crontab to run daily at 8am UTC
