Backup tool freezes

The backup tool can’t save all files from my site. It lasts too much time and the end it freezes. When I see if there’s any new file in my hosting, in the backup folder there’s a file with a strange extension, like this .zip.zAR11Y.

Anyone could help me to solve this issue?
Thanks.

I have the same issue here, tested with several version of grav (currently 1.7.25). Would love to see a solution!

@nix, Seems like someone has already created an issue about this issue… Grav 1.7.34 Backup never terminates or renders in Admin panel #3612

You might want to revive the issue…

Thanks!
I updated the issue.
