Hello @A412710 , it all depends on whether you have a backup of your Confluence data. If you've backed up your pages using Atlassian's native backup tool or a third-party solution like GitProtect backup and restore, you can simply initiate a restore process directly from your backup.

As noted by  @Tansu Akdeniz  and @Daria Kulikova_GitProtect_io  if you happen to have a backup, you can restore it... but that requires the backup :(
