A backup script to backup various things to my USB Drive

backup.rb

#!/usr/bin/ruby 
#copy ~/Library/keychain

#for testing
rsync_flags = "avzn --delete"

#for real...
#--delete => delete files which don't exist in the source
rsync_flags = "avz --delete"

remote = "/Volumes/Thor/nemo_backup"

#backup apple keychain items
`mkdir -p #{remote}/Library/Keychains`
`rsync -#{rsync_flags} ~/Library/Keychains/ #{remote}/Library/Keychains`

#backup this script
`rsync -#{rsync_flags} ~/manual_backup.rb #{remote}/`


#various directories to backup
dirs = "Music Pictures Sites Dropbox Reference Desktop".split(' ')

#backup each one.
#NOTE: the trailing slash on the source prevents the directory from being recreated at the destination
dirs.each do |dir|
  cmd = "rsync -#{rsync_flags} ~/#{dir} #{remote}"
  puts cmd
  puts `#{cmd}`
end
