rails_backup.md

• Install backup gem (http://backup.github.io/backup/v4/)

gem install backup

• Check available commands for generator

backup help generate:model

• Generate backup model. I chose backup to s3, you may choose any of available in docs.

backup generate:model --trigger=app_backup --databases='postgresql' --storages='s3' --compressor='gzip' --notifiers='mail'

• Following backup docs you can configure any kind of options for your specific case. My example is in app_backup.rb file
• As you setup all the options, check the backup execution backup perform -t app_backup
• To run backups on a schedule we need to install whenever

gem install whenever

• When that finishes, create a /config directory for Whenever inside ~/Backup:

cd ~/Backup
mkdir config

• Then run

wheneverize .

• This will create a schedule.rb file in ~/Backup/config for writing your cron jobs. Below is the code I added to mine:

every 1.day, :at => '11:30 pm' do
  command "backup perform -t app_backup"
end

• Cron will run the backup perform -t app_backup command. If you’d like to see this converted to cron syntax, run whenever:

$ whenever
30 23 * * * /bin/bash -l -c 'backup perform -t app_backup >> /home/bob/Backup/config/cron.log 2>&1'

• To write all the jobs to crontab we need to run:

whenever --update-crontab
