- What I did
preserve the file/directories structure, attributes etc during backup.
This is needed for example FRR configuration under /etc/sonic/frr might not be under root ownership. with the old backup method, the ownership etc will be lost.
- How I did it
use "cp -ar" instead of "cp -r"
- How to verify it
/etc/sonic/frr is under admin:admin, when it backed up, the structure and attributes were preserved.
