Backup MySql databases on localhost


2 posts in this topic

#1 ·  Posted (edited)

I was too lazy to frequent backups my database on localhost via phpMyAdmin so I wrote a very simple script to backup databases via command com. Maybe it will be useful to someone...

It backs up all or selected databases into one or separate sql files, e.g:

single file output:

20130406.022354_drupal,test.sql

separate files output:

20130406.022354_drupal.sql

20130406.022354_test.sql

Recommended php utility to import .sql files into MySql:

BigDump: Staggered MySQL Dump Importer

#include <Array.au3>
#include <Constants.au3>

; Definition and meaning:
; $export_defs .....    combine two constants: $cEXPORT_DB + ($cEXPORT_TO_... or $cEXPORT_AS_...)
;    e.g. [ $cEXPORT_DB_ALL_DATABASES + $cEXPORT_TO_SINGLE_FILE ] => export all dbs to one file
; $custom_dbs ...... user-created databases. Use comma as separator, e.g. "drupal, joomla"
; $export_path ..... an export destination folder
; $dbUsr ........... user login credentials, usually 'root'
; $dbPwd ........... passwords for MySQL accounts
; $dbSrv ........... MySQL server, 127.0.0.1 for localhost
; $sMySqlPath ...... full path to MySQL bin directory
; $sSytemDbs ....... list of databases created during installation MySql app

; use this constants in variable $export_defs:
Const $cEXPORT_DB_SYSTEMS_ONLY        = 1        ; export default databases (e.g. XAMPP default databases)
Const $cEXPORT_DB_NON_SYSTEMS        = 2        ; export user-created databases (e.g. all non XAMPP default dbs)
Const $cEXPORT_DB_ALL_DATABASES        = 4        ; export all databases
Const $cEXPORT_DB_CUSTOM_DATABASES    = 8        ; export selected databases (e.g. 'Drupal' database only)

Const $cEXPORT_TO_SINGLE_FILE        = 128    ; export databases as one .sql file
Const $cEXPORT_AS_SEPARATE_FILES    = 256    ; export each stored database as separate .sql file

HI Logman,

Forgot to thank you for sharing

i myself use a modified script of Matt Moeller "Auto MySQL Backup For Windows Servers By Matt Moeller v.1.5"

Yours is more configurable with your $export_defs
