Hi!

I use NFS on my NAS fileserver for create backups with innobackupex from my MySQL 5.7 in Linux Ubuntu 14.04.

If I use mkdir or touch commands in Linux with mounted NAS:

1. folders has 750 permissions (read&write&execute by owner, read&execute by group)
2. files has 660 permissions (read&write by owner, read&write by group)  
It’s OK, but I need write for group in bash scripts.  
So I create folders with specific permissions:  
mkdir -m 770 -p /mnt/dir

But if I use innobackupex command with mounted folder:

1. folders has 750 permissions (read&write&execute by owner, read&execute by group)
2. files has 640 permissions (read&write by owner, read by group)  
It’s not OK, because I really need write by group!

Why files and folders from cli innobackupex creates with these permissions?  
How to fix it?

I have the same situation as described here:  
[URL=“[https://www.linuxquestions.org/questions/linux-server-73/file-ownership-permissions-issues-on-nfs-fileshare-897122/](https://www.linuxquestions.org/questions/linux-server-73/file-ownership-permissions-issues-on-nfs-fileshare-897122/)”][https://www.linuxquestions.org/quest...eshare-897122/[/URL]](https://www.linuxquestions.org/quest...eshare-897122/%5B/URL%5D)

But I use ext4, not ext2.  
I’m still looking on NFS ACL solution… and still can’t understand why innobackup creates files with different permissions.
