PeaZip is a file compressor program similar to WinZip and WinRar and the popular open source compression software 7-zip. You can load multiple files or folders into one archive file that can be compressed to save disk space. A recent update to PeaZip allows it to easily integrate with the Windows Task Scheduler so you can compress and backup files.

We looked at using Windows batch files to automate file backups, which is a cool trick. However, using that method simply copies files from one place to another on a schedule. While that sounds just like what you’d want, it’s important to note that such a method is capable of using a ton of disk space.

PeaZip compresses file sizes to make their storage usage less than the original files. By using PeaZip with the Windows Task Scheduler program, we can easily schedule backups that also compress the files to ensure they take up less space than the originals.

If you’re short on backup storage, but need to backup files, this method we’ll look might be something you should try.

Steps to Create Automatic Compact Backups with PeaZip

Install PeaZip

The default steps when installing PeaZip will result in extra software that you may not want on your computer. Follow along as we ensure these programs aren’t installed.

Choose either “Standard installation” or “Custom installation” to begin the setup process. The latter option will enable you to customize a more detailed set of options for PeaZip. This can be done now or later during setup or later in the program menu.


Uncheck the box to install McAfee SiteAdvisor.


Continue on and uncheck the box to install Registry Mechanic by choosing “I do not accept.”


The program will install on your computer, so now we can configure Task Scheduler and PeaZip to work together.

Schedule Archives in PeaZip

Scheduling archives is done most easily from the right-click context menu. Find the folder you’d like to backup and then right-click on it. Select “PeaZip > Add to archive” from the context menu to open PeaZip with selected folder already in focus.


Choose an output location, file format type (like “ZIP”), compression strength (“Ultra,” “Store,” etc.), and any other available option. If you’re low on space, choose “Ultra,” just remember that the higher the compression rate, the higher the memory required to decompress it.


The “Schedule” tab determines the settings for how Task Scheduler will run this PeaZip operation. The purpose of this section is to run the previously selected settings on a schedule. When saving these options, we’ll see the task created in the Window Task Scheduler program.

Just like you’d expect, explain the task name (which can be anything), how often the task should run, and whether an admin’s or other user’s credentials should be used to run the task.

Press “Add Schedule” when finished.


A notification will show to indicate the exact command PeaZip sent to Task Scheduler to be used for running this archive task.


The task can now be edited in Task Scheduler like any other task. Any task created by PeaZip will be categorized in the Task Scheduler Library under the name “PeaZip.”


From this point on, you can disable the task or remove it from within the Task Scheduler program. There’s no need to return to PeaZip unless you’re creating a new archive task.


Backing up files is important if you’re dealing with sensitive or important data like documents, images, and the like. It’s a good idea to use a program like PeaZip so you’re not using up extra disk space just for your backup files.
