Daily Weekly Monthly

Keep your data safe by backing up on a daily, weekly and monthly basis.

This tool allows you to take regular backups whilst automatically removing old ones. Backups are stored in /(daily|weekly|monthly), and files are named using the format YYYY-MM-DD.

Installation

Using bundler:

gem "daily_weekly_monthly"

CLI:

gem install daily_weekly_monthly

Use

To use in your code, there is a single wrapper function to call:

DailyWeeklyMonthly.start(backup_command, options)

Where backup command is a string of the shell command you wish to run to get the database backup (to STDOUT), and options are a hash of options which are explained in detail below.

CLI

To use from the command line, just run the following after installing the gem:

daily_weekly_monthly "your backup command" [options]

Again, the options are explained below.

Configuration

Config is passed to the gem as a hash, with all possible options, their defaults and command line flags:

{
  backups_dir: "~/backups", # Where on the file system to store the backups
  output_extension: "pgdump.gz", # File extension to be appended to each backup
  day_of_week: 1, # Which day of the week to run weekly backups (0 - 6 where 0 is Sunday and 6 is Saturday)
  day_of_month: 1, # Which day in the month to run monthly backups
