how to make a tar file backup of a directory in python

Question

What I'm trying to do: I'm trying to make a recursive .tar file backup of the directory this python script is run in.

What I currently have:

import os
import zipfile
import datetime
import tarfile
datetime = str( datetime.datetime.now() )
def zipdir(path, zip):
    for root, dirs, files in os.walk(path):
        for file in files:
            zip.write(os.path.join(root, file))
backupdir = raw_input('Which directory should we backup to? \n')
if backupdir :
    try:
        zipf = zipfile.ZipFile('DrupalInstanceBackup'+datetime+'.zip', mode='w')
        zipdir('/Users/localuser/Downloads/backup', zipf)
    except Exception as e:
        print e
    finally:
        zipf.close()

What it currently does: It makes a .zip backup, but when extracted it doesn't show any files.

What Im trying to do: Can someone help me make this script recursively backup a directory and create a .tar archive of the directory and its files in a recursive manner?

Thank you

Solution

The good news is that tarfile supports recursively adding members any work.

with tarfile.open(archive_name + '.tar.gz', mode='w:gz') as archive:
    archive.add('/Users/localuser/Downloads/backup', recursive=True)

recursive=True is the default, so you can omit it.

Does this tar the files of the directory the script is in?

I think you figured it out, but it will tar files of directories you add with archive.add.

If you want to put all files from source dir without maintaining the complete dir structure, then you can pass arcname=''
