kb: technical Plesk Obsidian for Windows ABT: Group A

Applicable to:

  • Plesk Obsidian for Windows

Symptoms

  • It is not possible to unpack downloaded Plesk backup as .zip archive using Windows zip. (Backup was downloaded via Plesk > Tools & Settings > Backup Manager or Domains > example.com > Backup Manager):

    CONFIG_TEXT: Cannot complete the compressed (zipped) folders extraction wizard.
    The compressed (zipped) folder is empty.
    Before you can extract files, you must copy files to this compressed (zipped) folder.
    To close this wizard, click Finish.

  • It is not possible to unpack archive via WinRAR:

    CONFIG_TEXT: Archive is corrupt

Cause

In order to improve backup/restore operations speed and efficiently Plesk Obsidian Backup contains additional headers now. Which makes it impossible to open a backup file with native Windows File Manager.

For more details see "Plesk Backup Optimizations"

Resolution

This does not affect Plesk operations anyhow.

To be able to unzip backup please use 7-Zip software.
