• [SOLVED] ‘Byte of Python’ backup script question

1. [SOLVED] ‘Byte of Python’ backup script question
   

   I’ve recently started learning Pyhton (my first programming language actually) using the ‘Byte of Python’ guide by Swaroop. I’m currently at the stage where he walks us through writing a backup script and I’ve run into one small problem. Here is the code:

   Code:

   import os
   import time
   
       # 1. The files and directories to be backed up are specified in a list.
   source = ['/home/bandd/Python Scripts/']
   
       # 2. The backup must be stored in a main backup directory
   target_dir = '/media/Backup Bitch/BandD Backup/bandd/Python Scripts/'
   
       # 3. The files are backed up into a zip file
       
       # 4. The name of the zip archive isthe current date and time
   target = target_dir + time.strftime('%Y%m%d%H%M%S') + '.zip'
   
       # 5. We use the zip command (in Unix/Linux) to put the files in a zip archive
   zip_command = "zip -vr '%s' %s" % (target, ' '.join(source))
   
       #Run the back up
   if os.system(zip_command) == 0:
       print 'Successful backup to', target
   else:
       print 'Backup FAILED!'

   The target_dir is an external USB HDD, but I get an I/O error in the zip program that says:

   Code:

   zip I/O error: No such file or directory
   
   zip error: Could not create output file (/media/Backup Bitch/BandD Backup/bandd/Python Scripts/20080321212955.zip)
   Backup FAILED!

   If I change the target_dir to my home folder, it works fine. I even copied and pasted the mount point from the drive properties into the script after it failed the first time, with no luck. Is there something special I have to do to allow this python script access to the external hard drive? Just curious.

   Thanks,

   Dustin

   When working with strings, you need to escape the backslash.

   «» should be «\».

   Also, you should use methods of the os.dir if you are interested in portability, if it’s only for you, then go ahead. And try to check if folders/files exist before doing anything, it’s always a good practice.

   Thanks for the reply Can+~

   It helped me see my error. I’m learning to write bash scripts at the moment as well, and I forgot that Python handles spaces just fine with out the need of an escape. So I changed the path in the script to

   Code:

   /media/Backup Bitch/BandD Backup/bandd/Python Scripts

   and it worked.

   Also thanks for the tip on os.dir. Much appreciated!

   Hi,

   I also using the same but the prob I am getting is that when zip command zip files, it takes full path like /home/user/Desktop/Backup/.

   I also tried to use gllo.glob but that also just include files form main folder and subfolders but no file from subfolders.

   Similarly I used os.walk(source) but in that one also it takes all files form main folders and subfolders and then write to .zip file without directory structure.

   Can you please suggest if I can use zip command to create actual Folder path only or glob.glob so that it include subfolder’s files also or os.walk for real directory structure. Thanks in advance.

   Akash…
