From e7f996c480b3be437794041077b297f3e9ddc1bb Mon Sep 17 00:00:00 2001 From: Hui Lan Date: Sat, 7 Dec 2019 09:58:54 +0800 Subject: create backup_files.py for backing up files Define a function copy_and_backup_file(src_file, dest_dir) to do backup and compression work. The function copy_and_backup_file is used in update_network_by_force.py. -Hui --- Code/update_network_by_force.py | 227 ++++++++++++++++++++-------------------- 1 file changed, 114 insertions(+), 113 deletions(-) (limited to 'Code/update_network_by_force.py') diff --git a/Code/update_network_by_force.py b/Code/update_network_by_force.py index 7ba8c87..11e8d72 100644 --- a/Code/update_network_by_force.py +++ b/Code/update_network_by_force.py @@ -1,113 +1,114 @@ -# Usage: python3 update_network_by_force.py -# Purpose: update_network.py could take a few days to run.
