Q100039: Restoring a Mari project from a backup

Follow

SUMMARY

This article explains how to restore your project from an automatically generated backup file located in your project directory, however please be careful and always make sure to make a backup copy of the affected project before following each step precisely.

The most common reason to require a backup is Project corruption, which can have various causes. It's often caused by interactions over the network or changes to the folder structure of your project, such as those potentially inflicted by disk cleanup tools. The consequence is that the user is no longer able to open their Mari Project.

 

MORE INFORMATION

Please follow these instructions carefully, as deviation can cause additional issues.
  1. Launch Mari.

  2. Hover your mouse over the affected project in the project tab until the tooltip pops up.

  3. Write down the first 4 digits of the UUID.

  4. Close Mari - very important! If Mari is open during the next steps, irreversible project corruption can occur.

  5. Open a file browser and navigate to your Project directory. Your Project directory is set 

  6. You will see a number of folders each with long hash names. These are your Projects, and they should look something like this:



  7. Select the folder that starts with the UUID of your affected project (noted down in step 3) and copy it to another safe location. This is so that you have a copy of the Project, as the next steps can cause irreversible changes.

  8. Now open the folder that starts with the UUID noted earlier (the one in the project directory, not the copy done in Step 7).
    You should see something like this:
  9. Rename Project.mri to Project.OLD

  10. Rename Project.mri.bak to Project.mri

  11. Now start Mari again and attempt to open your archive.
