I have a file which is
backup-2022_06_04.zip.locked
on linux Confluence server, which is on folder:
/var/atlassian/application-data/confluence/backups
I have renamed that file into backup-2022_06_04.zip, but I can't use it.

I have also checked that I can not actually unzip it.
Is there any way to restore data from such file?
(I can not export space actually).
