NAME

narada-mysqldump - dump project database

VERSION

This document describes narada-mysqldump version 1.2.1

USAGE

    narada-mysqldump

DESCRIPTION

Backup your Narada project's MySQL database.

If "config/db/db" absent or empty do nothing.

Dump database as quickly as possible to files "var/sql/*.sql":

  • Tables listed in "config/db/dump/ignore" doesn't included in dump (even in database scheme).

  • Database scheme saved in "var/sql/db.scheme.sql".

  • Content for tables listed in "config/db/dump/empty" doesn't dumped.

  • Content for tables listed in "config/db/dump/incremental" saved in "var/sql/TABLE_NAME.FROM-TO.sql".

    • Only new rows will be saved, which is absent in already existing files.

  • Content for other tables saved in "var/sql/TABLE_NAME.sql".

    • If table wasn't changed since previous dump - do nothing and just keep file with previous dump.

  • All other "*.sql" files will be removed from "var/sql/".

To force full dump (including incremental and unchanged tables) run "rm var/sql/*.sql" before "narada-mysqldump".

Will set exclusive lock on this project while doing database analyse and dumping database scheme and non-incremental tables. Incremental tables will be dumped after releasing lock.

Will set dump file's mtime to Update_time of related database table, and use mtime on next dump to detect table change.

All incremental tables MUST have first column's type "INT AUTO_INCREMENT PRIMARY KEY" (can also use "MEDIUMINT", etc.).

After ALTERing incremental table or doing TRUNCATE existing files with incremental dumps will be automatically removed and replaced by new ones.

Tables listed in "config/db/dump/empty" and "config/db/dump/incremental" must exists; listed in "config/db/dump/ignore" may not exists.

Script must be executed only from "project root directory".
