BackupFu ======== The backup_fu plugin makes it redonkulously easy to: A) dump your database and/or static files to tar/gzipped or zipped archives, and B) upload these archives to a private Amazon S3 bucket for safekeeping Allows restore of PostgreSQL databases. It also uses credentials in config/amazon_s3.yml if not supplied in backup_fu.yml Installation ============ The 'right_aws' gem is required for backup_fu to function properly. Install with: sudo gem install right_aws Install the plugin with: script/plugin install git://github.com/gravelpup/backup_fu.git Configuration ============= Run the following to copy over the example backup_fu.yml config file: rake backup_fu:setup This copies the example config file to: config/backup_fu.yml. Usage ===== For the list of available rake tasks: rake -T backup_fu Backing up your database: rake backup Dumping your database: rake backup_fu:dump Backing up your static files: rake backup_fu:static:backup Backing up both your database + static files: rake backup_fu:all Restoring from S3: BACKUP_FILE=myapp_1999-12-31_12345679_db.tar.gz rake backup_fu:restore Advanced Configuration ====================== See vendor/plugins/backup_fu/config/backup_fu.yml.advanced_example for the list of advanced configuration options. Advanced options include: * specify static path(s) that should be backed up -- i.e. backup your entire 'public/static' directory * change default dump path from RAILS_ROOT/tmp/backup to whatever * specify fully-qualified 'mysqldump' path * disable compression of database dump * choose between zip or tar/gzip compression * enable 'nice' with level specification to prevent backup_fu from bogarting your server Cronjob Installation ==================== Here are some cron job examples. # Backup just the database everyday at 1am 0 1 * * * cd /apps/foo/current; RAILS_ENV=production rake backup > /dev/null # Backup db + static @ 2am every 3 days, log the results to ~/backup.log (verbosity should be turned on if logging results) 0 2 1-31/3 * * cd /u/apps/shanti.railsblog/current; RAILS_ENV=production rake backup_fu:all >> ~/backup.log Debugging ========= --- Enabling Verbosity If you are experiencing any difficulties, the first thing you should do is enable verbosity by dropping this into config/backup_fu.yml: verbose: true --- Mysqldump Issues If your 'mysqldump' command is not in your path, you will need to specify it explicitly. To see if mysqldump is in your path, execute: which mysqldump If you see output like "/usr/bin/which: no mysqldump in (...)" then you will need to specify the path manually. Use 'locate mysqldump' or a similar tool to find the full path to your mysqldump utility. Place an entry like the following in your config/backup_fu.yml file: mysqldump_path: /usr/local/mysql-standard-5.0.27-linux-i686/bin/mysqldump --- Database Connection Issues If you are seeing an error when running 'rake backup' like: mysqldump: Got error: 2002: Can't connect to local MySQL server ... Make sure you are specifying the RAILS_ENV for the target environment. i.e. for production: RAILS_ENV=production rake backup or rake backup RAILS_ENV=production --- Connection reset by peer When backing up, if you receive an error like: rake aborted! Connection reset by peer Chances are this is because your backup is huuge. There is currently no great solution for this problem. On some systems, I have backed up 4GB+ files without a hitch. On other machines, an 80mb backup was choking on the S3 upload. After 3 attempts it went through. Patching in some kind of email notification system on failure would probably be nice. Patches welcome =) --- Tiny Static file .tar.gz Archive (static files not actually getting archived) This may result if you are using a symlink for your static dir, such as: public/static -> /shared/apps/foo/static The solution to this is to specify the absolute static path in config/backup_fu.yml: static_paths: /shared/apps/foo/static Copyright (c) 2009, released under the MIT license
