= Backup utility for database, folders and files Backs up a MySQL database, folders and files to a default folder (~/backup) or to a specified folder. If the --cron switch is provided the specified database and files are not backed up rather a cron job of the provided command is added to crontab. == Install The application can be installed with $ gem install syc-backup == Usage Backup a database to the default folder _~/backup_ $ sycbackup -d database -uuser -ppass Backup a MySQL database, a directory and files to the default folder $ sycbackup -d database -uuser -ppass -f directory,file1,file2 Specify a backup folder $ sycbackup backup/folder -d database -uuser -ppass -f directory,file1,file2 Override files in the backup folder if they exist $ sycbackup backup/folder --override -f directory,file1,file2 Don't compress the backup $ sycbackup --no-compress -f directory,file1,file2 Create a cron job that is scheduled every day at 2:30 $ sycbackup -d database -uuser -ppass -f directory,file1 --cron 30,2,*,*,* If the user or password contains characters as '(' you have to escape them. A password like 123(56 has to be provided with pass\"123\(56\". == Usage of --override and --no-compress Whether the backup directory and the backup files are time stamped depends how --override and --no-compress is set. The results are shown in the table below. --override --no-compress backup directory backup file(s) 0 0 w/o timestamp w/ timestamp 1 0 w/o timestamp w/ timestamp 0 1 w/ timestamp uncompressed 1 1 w/o timestamp uncompressed == Supported Platform syc-backup has been tested with 1.9.3 == Notes The application backs up the MySQL database with _mysqldump_. The dumpfile has the form yyyymmdd-HHMMSS_databasename.sql. After the files are backed up the dumpfile will be deleted. If the --no-compress is provided the files are copied to the backup folder. Otherwise they are compressed with _tar cfz YYYYmmdd-HHMMSS_syc-backup.tar.gz_. If the --override switch is not provided the backup directory will be added a timestamp. So if you create a cron job you should every now and then delete obsolete backup folders. The source contains lib/backup/file_backup.rb which is not used in the application. == Tests The tests create folders and files and will be deleted after the tests finish. _MySQLBackup_ needs to run a MySQL database with a database _test_ and a user _user_ with the password _pass_. The test files live in the test folder and begin with test_. There is a rake file available which can be used to run all tests with $ rake test == Links * [http://sugaryourcoffee.github.com/syc-backup] - RubyDoc * [http://www.github.com/sugaryourcoffee/syc-backup] - Source code on GitHub * [http://syc.dyndns.org/drupal/content/backup-drupal-database] - Development notebook * [https://rubygems.org/gems/syc-backup] - RubyGems

sym-crypt is a core encryption module for the symmetric encryption app (and a corresponding gem) "sym", and contains the main base serialization, encryption, encoding, compression routines. sym-crypt uses a symmetric 256-bit key with the AES-256-CBC cipher, which is the same cipher as the one used by the US Government. For encyption with a password sym-crypt uses AES-128-CBC cipher. The resulting data is zlib-compressed and base64-encoded. The keys are also base64 encoded for easy copying/pasting/etc.

Bitfifo implements a FIFO for 1 or more bits of an Integer. This will be needed for a compression and encryption system. Could be used for any variable length integer based problems including base64 encode/decode. Includes bit reversals for LSB first or MSB first systems. No need to worry about overfill as a Bignum is used to store bits.

Dialect is a framework that provides a way to describe your application in terms of activity and page definitions. Those definitions can then be referenced by test libraries using the DSL that Dialect provides. The DSL provides a fluent interface that can be used for constructing test execution logic. This fluent interface promotes the idea of compressibility of your test logic, allowing for more factoring, more reuse, and less repetition. You can use Dialect directly as an automated testing solution or you can use it with other tools such as RSpec, Cucumber, or my own Lucid tool.

ZOpen allows reading and writing of possibly compressed files (e.g. gzip, bzip2 or xz compressed files), either using the corresponding gems or external command line tools.
