Backup Scheduler


With this plugin, you may plan the backup of your entire website (folders, files and/or database).

You can choose:

  • which folders you want to save;
  • the frequency of the backup process;
  • whether your database should be saved;
  • whether the backup is stored on the local website, sent by email or stored on a distant FTP (support of multipart zip files)

This plugin is under GPL licence

Multisite – WordPress MU

This plugin is compatible with Multisite installation.

Each blog administrator may save their own data.

The super-admin may save either its data or the whole website. By saving the whole site, the admin may create different SQL files for the subsite in order to ease the restoration of a single sub-site.

Features of the framework

This plugin uses the SL framework. This framework eases the creation of new plugins by providing tools and frames (see dev-toolbox plugin for more info).

You may easily translate the text of the plugin and submit it to the developer, send a feedback, or choose the location of the plugin in the admin panel.

Have fun !

Installation Instructions
  1. Upload this folder backup-scheduler to your plugin directory (for instance ‘/wp-content/plugins/’)
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Navigate to the ‘SL plugins’ box
  4. All plugins developed with the SL core will be listed in this box
  5. Enjoy !
Forced backup never ends (but there is no displayed error)

Be sure to stay on the configuration page : if you quit the page, the forced backup process will be killed !

Scheduled backup is stucked

Scheduled backup only works on website that have traffic.

Indeed, each visits triggers a piece of the backup process.

Thus, if there is no traffic, the schedule backup process wont’t occur. If there is very little traffic, the backup will be very long, etc

I have an error message indicating that another backup is running

This message may happen if the chunk size is set quite high. For instance, 40 Mo is clearly too big and server server configuration of many webhosters will kill scripts which use too much memory.

Most of the case 5Mo is ok.

If you get this error, set the chunk size to 1Mo and if it solves your problem, increase this chunk size.

Compatible Archive Software

The backup will be in a multi-part format. In order to uncompress it, you should put all the backup in the same folder and open the .zip file with Winzip.

You may experience some “corruption” error. It is mainly due that archive software are not compatible with multi-part archives. I have tried with success:

  • Winzip (version 16.0 tested),
  • WinRar (some issue with UTF8 characters), and
  • IZArc (some issue with UTF8 characters).
NOT-Compatible Archive Software

These software are not compatible with multi-part archives:

  • 7-zip, and
  • the Windows Explorer embedded function.

Do not hesitate to contact me if you face some issues.

To restore the backups
  • install a fresh version of WordPress on your server ;
  • unzip the backup (actually, the zip file comprises a plurality of files i.e. a multi-part zip (zip, z01, z02, etc.). These files should be saved in a same folder and your zip program (such as IZArc, Winzip, Winrar, …) will do the job for you…
  • If you have configured to save the entire installation, replace all the wordpress files by the one in the zip file and import the SQL files (at the root of the zip file, the files named *.sql1, *sql2, etc.) in your database (with for instance phpmyadmin). It is recommended to save your database first ;
  • In other cases, replace the ‘plugins’, ’themes’, ‘uploads’ folders (in the wp-content folder) with the one in the archive, replace the wp-config.php (at the root of your wordpress repository) with the one at the root of the zip file and import the SQL files (at the root of the zip file, the files named *.sql1, *sql2, etc.) in your database (with for instance phpmyadmin). It is recommended to save your database first.
The backup files are corrupted

Be sure that all thz zip files (i.e. .zip, .z01, z02, etc.) are in the same folder.
If you have still this issue, please try with Winzip software.

Finally a plugin that supports the backup of multisites and it works beautifully! Thanks so much for all your work and for providing such a great plugin. You are awesome!

Have quietly relied on Backups Scheduler for years. It has saved the day several times. Work your way through the options, all is there. Never a conflict with theme or other plugin. On rare occasions when I do not receive my morning email assurance that the backup completed, I find it happened to coincide with some other processes maxing out memory on the shared server causing it to hang. Go to dashboard, clear, and initiate a manual backup. (Do not close that backup page or tab until completed.) When I was a new to WP, this plugin developer was very responsive and helpful. Has since incorporated answers to those questions in his documentation. Mature plugin.

Good multi site backup for Free Host Accounts (Hostinger, 000webhost, etc). But it did not work fully for cloning/migrate the site. The sql backup seems to be incomplete. I needed to do a full export on phpMyAdmin to be able to clone my multisite from Hostinger to openshift. (If developer wants to know the error I am willing to give him feedback) Needs an option to turn off scheduler or to have only on demand backups. For a blog site this maybe not needed as comments are created continuously, but for a static site there is no need to have schedule backups, since there are not any changes besides occasionally plugins updates and sporadic page changes.

This is great. Now if I have a problem on one site I can restore just that one site. I backs up the upload site folder and does a db backup of just that site number. I set it to email me the backup zip and I then autoforward that to dropbox (to resolve the issues where a failure happened in emailing to dropbox that I didn't see) Great

Installed under WP 4.3 Multisite installation and attempted Network Activation. Received an error message that said 261 characters of unexpected output were received and suggested deactivating and removing if syndication errors occurred. Couldn't find network instructions for usage. Deactivated and removed.
