I don't see your username lubash in the backup system, so I can't find the backup to see what format it is in. Keep in mind that users cannot restore a complete pleskbackup_*.tar file by design. It MUST be unpacked and manually restored.
If your backup file is called pleskbackup-<username>.tar, then these are the instructions to get your files out of the backup: https://wiki.helionet.org/Account_Backups#Access_Your_Files Once you get the files out, you upload them manually via SFTP or Plesk.
If it's called <username>_2026-05-08.tar (or similar, date may vary), you just open it in 7zip or a similar program and extract the files, then upload the ones you need. Depending on what data was available, there will either a folder full of files from your home directory, or a folder of files alongside a pleskbackup_<username>.tar (which will contain an older backup that also has databases in it).
