# butterbackup
A backup solution. A server at your office behind your firewall that pulls data from public servers and saves snapshots.
A backup solution. A server at your office behind your firewall that pulls data from public servers and saves snapshots.
# On your backup server
Create a partition from free space
cfdisk /dev/sda
apt-get install parted
partprobe
apt-get install btrfs-tools
mkfs.btrfs /dev/sdaX
mkdir /backups
mount /dev/sdaX /backups
## Mount the partition on boot
Find the UUID of the new partition
blkid
Edit /etc/fstab
UUID=7ef18851-xxxx-yyyy-zzzz-53f7b88b6119 /backups btrfs defaults 0 0
## Setup butterbackup
apt-get install git
cd /opt
git clone https://gitlab.com/lleialtec/butterbackup.git
Instalar python3 en un entorno virtual
apt-get install virtualenv
cd /opt/butterbackup
virtualenv venv --python=python3
# Setup users
butterbackup runs on the backserver as root. root connects to the public server as user keeper
We create a user on the public server and copy root@backup_server public key to keeper@public_server authorized_keys
On the public_server
adduser --disabled-password keeper
mkdir /home/keeper/.ssh
touch /home/keeper/.ssh/authorized_keys
## Create root@backup_server ssh keys on the backup_server
ssh-keygen -t ecdsa -b 521
And add the new public key to keeper@public_server /home/keeper/.ssh/authorized_keys
Test to see if you can open a session on the public_server
ssh keeper@public_server
## Permissions
Perhaps keeper@public_server does not have permission to read everything you want to backup.
Let's say you want to backup /var/www on the public server.
You can add the keeper to the www-data group
# Create a config file
cd /opt/butterbackup/config
cp example.com my_server_domain_name.com
Edit the new config file.
# Make the first copy
You can run butterbackup manually
/opt/butterbackup/venv/bin/python3 /opt/butterbackup/butterbackup.py my_server_domain_name.com
# Inspect backups
cd /backups/my_server_domain_name.com
