EZ drop in backup rake task for your rails projects - works well - 5 - 10 min set up, one rake file and one config file
backs up db and any directory's to any number of servers with rsync
BSD License or whatever, but it would be cool if you told me your using it
2007 ISS http://industrialstrengthinc.com
this is a sample config file and a rake task you can drop into any rails project to do backups, easy to automate.
Backs up your specified environment db to activerecord yml files (one per table) and zips them up in a human readable timestamped file
syncs that and any other set of arbitrary directory's to any number of arbitrary servers with rsync
be sure to set ssh key based logins
to run: rake backup
also: rake backup:db, rake backup:restoredb (promts for a file created by backup:db), rake backup:push (to push out what u got)
note: this uses something like 30 lines of code from some blog site I got it from that I cant recall, yay for that guy, thanks
