We can use the set/get facl utility for restoring server file permissions.
The below command would be for creating a permissions.acl file (containing all permissions on a set of files) in /
getfacl -Rp / > permissions.acl
The below command is for using the file created above to set permissions:
setfacl --restore=permissions.acl
