Yii backup module


To add this module to your app, just run:

 $ composer require floor12/yii2-module-backup

or add this to the require section of your composer.json.

 "floor12/yii2-module-backup": "dev-master"

After that, include minimal module configuration in modules section of application config:

 'modules' => [
             'backup' => [
                 'class' => 'floor12\backup\Module',
                 'administratorRoleName' => '@',
                 'configs' => [
                         'id' => 'main_db',
                         'type' => BackupType::DB,
                         'title' => 'Main database',
                         'connection' => 'db',
                         'limit' => 10
                         'id' => 'main_storage',
                         'type' => BackupType::FILES,
                         'title' => 'TMP folder',
                         'path' => '@app/tmp',
                         'limit' => 2

These parameters is possible to set up:

  • administratorRoleName - role to access web controller
  • backupFolder - path alias to the place where backups are stored (default is @app/backups)
  • chmod - if this param has value, the new backup file will change mode after creation
  • authTokens - array of auth tokens to use REST-API of the module
  • ionice - the value of this param will be placed before ZIP console command in case of disk backup (for example it's possible to put iotince -c3 inside this param to run backup creation with IDLE disk i/o priority)
  • adminLayout - it will change default main layout to something you need (if your admin panel has different base layout)

And the main and required param is configs - its an array of your backup items (folders and databases). Each backup items mast have this elements to set:

  • id - backup identifier, contains only letters and numbers without space
  • type - type backup: disk or database
  • title - human-readable backup item title to show in the admin interface
  • limit - how many backup copies keep before delete (0 - never delete old copies)
  • connection - in case of database backup, connection name in Yii2 config
  • path - in case of disk backup, the path to store backup files


WEB interface

This module has a web controller to work with backups. Go to backup/admin or backup/admin/index to create, delete, restore and download backups.

Console interface

To list all existing backups run

$ ./yii backup/console/index>

To create config run

$ ./yii backup/console/create <backup_config_id>

backup_config_id is backup item identifier from module configuration.

To restore config run

$ ./yii backup/console/restore <backup_id>

backup_id is identifier of backup stored in sqlite database


By default, the rest controller takes place on the route /backup/api. To get access to it, add header Backup-Auth-Token to request with one of the tokens stored in application config in the module section (param authTokens);

Get list of backups

GET /backup/api/index

This is useful to remote backup checks from some dashboard with a few projects.
