backuppc setup


Sun virtual box
created new VM, dynamicaly expanding HD (~90gb)
set up networking for bridged
set the mac address to:  08:00:27:44:43:FB
create backup pool HD
in the settings menu, click the + icon on the HD icon; select "create"
make it dynamically expanding
name it backuppc_pool, and save it to an external HD
make its size 940gb
on the command line
$ VBoxManage modifyhd $PATH_TO_HD --type writethrough
fresh install of ubuntu 9.10 server
default options until hostname
@hostname = backuppc-server
@partition disks = Guided use entire disk and set up LVM
@set up users and passwords
new user = bgadmin
username for your account = bgadmin
password (for development) = qaz
dont encrypt home directory
@select and install software
no automatic updates
@software selection only choose OpenSSH Server
reboot, removing the virtual cdrom

CREATE SNAPSHOT OF FRESH INSTALLATION (fresh install)

Update/upgrade all packages
$ sudo apt-get update
$ sudo apt-get upgrade

CREATE A NEW SNAPSHOT AFTER UPDATES (updates post fresh install)

Install Avahi
$ sudo apt-get install avahi-daemon
configure avahi
$ sudo vi /etc/avahi/avahi-daemon.conf
#host-name=foo => host-name=backuppc-server
Install Backuppc
$ sudo apt-get install backuppc
local only for postfix configuration
default for system mail name
apache2 for backuppc
web user with the following credentials
backuppc
xliI1Raf (change with `htpasswd /etc/backuppc/htpasswd backuppc`)
$ sudo htpasswd /etc/backuppc/htpasswd backuppc
chaned to: cinagro77
Install PureFTPd
$ sudo apt-get install pure-ftpd

CREATE A SNAPSHOT AFTER MAIN APPLICATIONS ARE INSTALLED

PureFTPD configuration
$ sudo groupadd ftpgroup
$ sudo useradd -g ftpgroup -d /dev/null -s /etc ftpuser
$ cd /etc/pure-ftpd/auth
$ sudo ln -s /etc/pure-ftpd/conf/PureDB 50pure
$ sudo mkdir -p /var/ftp/pureftp/bguser (create that structure)
$ sudo pure-pw useradd bguser -u ftpuser -g ftpgroup -d /var/ftp/pureftp/bguser
using password: cinq50
$ sudo pure-pw mkdb
$ sudo vi /etc/pure-ftpd/conf/PAMAuthentication
yes => no
create folders and set permissions for file transfers
$ cd /var/ftp/pureftp/bguser
$ sudo mkdir server-key client-keys client-configs default-configs client-kh
$ sudo chown root:ftpgroup *
$ sudo chmod g+r-w server-key default-configs
$ sudo chmod g+w-r client-*
restart pureftp
$ sudo /etc/init.d/pure-ft restart

BackupPC configuration - SSH/config files
$ sudo su -s /bin/bash backuppc
$ cd /etc/backuppc
$ mkdir client-keys client-kh client-configs
$ rm /etc/backuppc/pc
$ ln -s /etc/backuppc/client-configs/ /etc/backuppc/pc
$ mkdir .ssh
$ chmod 700 .ssh
$ cd .ssh
$ ssh-keygen -t rsa -f id_rsa -N '' (pair of single quotation marks)
$
$ touch authorized_keys known_hosts
$ chmod 600 authorized_keys known_hosts  (should be needed, use if authorized_keys isnt writeable)
$ exit (go back to bgadmin)
$ sudo chown backuppc:www-data /etc/backuppc/client-configs /etc/backuppc/pc
copy the server ssh key to the appropriate directory for the clients to get
$ sudo cp /etc/backuppc/.ssh/id_rsa.pub /var/ftp/pureftp/bguser/server-key/backuppc_id_rsa.pub
$ sudo chown root:ftpgroup /var/ftp/pureftp/bguser/server-key/backuppc_id_rsa.pub
$ sudo chmod g+r /var/ftp/pureftp/bguser/server-key/backuppc_id_rsa.pub


Add bgadmin to the working groups for this project
$ sudo usermod -a -G backuppc,ftpgroup bgadmin


CREATE A SNAPSHOT AT THIS POINT
$ sudo shutdown -P now


Making the initial backup pool HD
$ sudo parted /dev/sdb
mklabel
gpt
mkpart
backuppc_pool
ext4
0%
100%
quit
sudo mkfs.ext4 -L backuppc_pool /dev/sdb1

Pointing the pool to the new disk
mount the fresh filesystem
$ sudo mount -t ext4 /dev/sdb1 /mnt
copy the files residing where the mount point will be
$ sudo cp -dpR /var/lib/backuppc/. /mnt
unmount the filesystem
$ sudo umount /dev/sdb1
move the fresh directory in case of foul up (can also use the original directory on a fresh drive)
$ sudo mv /var/lib/backuppc /var/lib/backuppc.orig
make the new directory, that will be the mount point
$ sudo mkdir /var/lib/backuppc
mount the filesystem to this diectory
$ sudo mount -t ext4 /dev/sdb1 /var/lib/backuppc
if everything is ok, add the mount to fstab
$ sudo vi /etc/fstab (deliniated with spaces, I believe)
LABEL=backuppc_pool    /var/lib/backuppc    ext4    defaults,auto    0    2


BackupPC configuration - Migrate default .SSH directory
make a link to the .ssh directory in .etc
$ sudo ln -s /etc/backuppc/.ssh /var/lib/backuppc/.ssh


Make a very simple script to automate moving new client data
$ sudo vi /sbin/import-client-data
#! /bin/bash
echo "Copying client configuration files..."
mv -uv /var/ftp/pureftp/bguser/client-configs/*.pl /etc/backuppc/
echo "Combining client rsa keys..."
mv -uv /var/ftp/pureftp/bguser/client-keys/*.pub /etc/backuppc/.ssh/client-keys/
mv -uv /var/ftp/pureftp/bguser/client-kh/*.kh /etc/backuppc/.ssh/client-kh
cat /etc/backuppc/.ssh/client-keys/*.pub > /etc/backuppc/.ssh/authorized_keys
cat /etc/backuppc/.ssh/client-kh/*.kh > /etc/backuppc/.ssh/known_hosts
$ sudo chmod +x /sbin/import-client-data (always run the script with sudo)
