mattgaidica / Better Database Pulling With Heroku
Created June 23, 2012 04:37 — forked from jackkinsella/Better Database Pulling With Heroku
Taps isn't reliable for anything but dummy databases. This command invokes the more powerful PGBackups. A side effect is that every time you pull your database locally a backup is also generated on your server.
#!/bin/bash
# Best use case is to create a file "update_local_db.sh" in your project folder and then call the command with bash update_local_db
# Follow me: @jackkinsella
function LastBackupName () {
heroku pgbackups | tail -n 1 | cut -d"|" -f 1
}
# This part assumes you have a low limit on no. of backups allowed
