New page

=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++ python3-llfuse

== 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

#borg backup
30 8 * * * root /srv/borg.sh

Reload the crontab file

service cron reload

= Mounting and restoring =
Borg makes it easy to mount a backup on the server using "borgfs".

If this is done on a different server or during a restore operation on new servers, the key files need to be imported from the paper key. Selected admin users have the paper keys backed up in encrypted email.

For example on a our db-fnt server:

Take the first 5 lines from the /srv/borg.sh file and export them on the cli:

export BORG_REMOTE_PATH=/usr/local/bin/borg1/borg1
export HOST=
export BORG_REPO=
export BORG_PASSPHRASE=
export BORG=/usr/local/bin/borg

Note if doing this on a different server, BORG_REPO= must be the server you intend to restore from.

#import the paper key
borg key import --paper $BORG_REPO

#make a directory to mount the backups on:
mkdir /mnt/backups

#now mount the borg repo
borgfs $BORG_REPO /mnt/backups/

The files will now be in /mnt/backups:

ls /mnt/backups/
db-fnt.allstarlink.org-2018-10-31_08:30 db-fnt.allstarlink.org-2019-02-28_08:30

db-fnt.allstarlink.org-2019-02-17_08:30 db-fnt.allstarlink.org-2019-03-07_08:30
db-fnt.allstarlink.org-2019-02-24_08:30 db-fnt.allstarlink.org-2019-03-08_08:30

You can now go into any of these directories and restore files as of the date for the respective directory using normal UNIX utilities.
