Automatic Backup Plan with Backup Gem , Setting up automatic schedules backup plan for a single server using backup ruby gem and local storage or you can use amazon was s3 buckets there are many choices including dropbox but in this post I will only cover local storage mode , you can use cloud storage sync and backup providers to sync backups eg. copy.com and mega.nz etc.
so let’s get started to ” Automatic backups with Backup Gem “.
Please Note: This is intended for single , or personal server . please learn backup gem documentation before using in production . for large and huge distributed applications please see some-other backup solution .
Automatic Backup WorkFlow
- We will use backup ruby gem , and write some ruby scripts to perform backups of files and database .
- after that it will send notification email .
- we will set crontab to perform this job every day .
Intro to Backup Gem
Backup is ruby gem written by Michael van Rooijen . its provide simple ruby DSL for backup . its easy to use and feature rich . overall its great for backup if you don’t have any ruby background d. don’t worry its simple as writing 5 lines in human language , additionally for security you can encrypt all backup files .
Backup allows you to model your backup jobs using a Ruby DSL
okay lets setup BackUp Gem
Backup gem is ruby gem so lets install ruby first then we will setup backup gem .
sudo apt-get install curl build-essential curl -sSL https://get.rvm.io | bash -s stable --ruby --gems=backup,whenever source $HOME/.rvm/scripts/rvm rvm use ruby gem install backup
okay lets setup first backup model . in this model we are going to backup nginx files .
backup generate:model --trigger nginx_backup --archives --storages='local' --compressor='gzip' --notifiers='mail'
output will look like this
Generated configuration file: '/home/alok/Backup/config.rb'. Generated model file: '/home/alok/Backup/models/nginx_backup.rb'.
okay lets create our first model to backup nginx config files on daily basis . you can use this kind of models according to your requirements like backing up your WordPress based blog and other stuffs .
you can also add mysql block in model to backup your mysql database .
nginx_backup.rb to backup nginx configurations
# encoding: utf-8 ## # Backup Generated: nginx_backup # Once configured, you can run the backup with the following command: # # $ backup perform -t nginx_backup [-c ] # # For more information about Backup's components, see the documentation at: # http://meskyanichi.github.io/backup # Model.new(:nginx_backup, 'Description for nginx_backup') do ## # Archive [Archive] # # Adding a file or directory (including sub-directories): # archive.add "/path/to/a/file.rb" # archive.add "/path/to/a/directory/" # # Excluding a file or directory (including sub-directories): # archive.exclude "/path/to/an/excluded_file.rb" # archive.exclude "/path/to/an/excluded_directory # # By default, relative paths will be relative to the directory # where `backup perform` is executed, and they will be expanded # to the root of the filesystem when added to the archive. # # If a `root` path is set, relative paths will be relative to the # given `root` path and will not be expanded when added to the archive. # # archive.root '/path/to/archive/root' # archive :my_archive do |archive| # Run the `tar` command using `sudo` # archive.use_sudo archive.add "/etc/nginx/" end ## # Local (Copy) [Storage] # store_with Local do |local| local.path = "/home/alok/backup/nginx" local.keep = 5 end ## # Gzip [Compressor] # compress_with Gzip ## # Mail [Notifier] # # The default delivery method for Mail Notifiers is 'SMTP'. # See the documentation for other delivery options. # # notify_by Mail do |mail| mail.on_success = true mail.on_warning = true mail.on_failure = true mail.from = "email@example.com" mail.to = "firstname.lastname@example.org" mail.address = "smtp.gmail.com" mail.port = 587 mail.domain = "your.host.name" mail.user_name = "email@example.com" mail.password = "my_password" mail.authentication = "plain" mail.encryption = :starttls end end
adjust email setting accordingly .
you can generate and use these kind of models to backup your wordpress , forums or any kind of files .
Cron is a time based job scheduler for unix like operating systems . we can use cron to schedule to run backup script accordingly .
there is awesome gem in ruby called “whenever ” is provide great dsl for writing cronjobs . and great thing about whenever is its supported by backup gem . means you can use whenever gem with backup script .
gem install whenever cd ~/Backup #whenever gem expect a file named `schedule.rb` inside `config` directory so lets create it mkdir -p config/ touch config/schedule.rb wheneverize
okay lets setup crontab using whenever gem to trigger
nginx_bakup daily at 12AM
every 1.day , :at => '12 am' do command "backup perform -t nginx_backup" end
okay lets check syntax and all other configs
backup check # Sample output [2014/10/05 07:51:02][info] Configuration Check Succeeded.
now lets write cron using whenever gem
cd ~/Backup whenver -w
Now relax , you can use any cloud based storage and sync service to sync your backup files ( eg. copy.com, mega.nz etc ).
