Hello,

I'm using Python to automate admin tasks on my job. We use Windoze
2000 as desktop platform. When executing this daily backup scripts I
get the following error:

Traceback (most recent call last):
File "C:\UTILS\backup.py", line 8, in ?
TarFileBackup = tarfile.open(NewBackupFilename, 'w:bz2')
File "C:\Python23\lib\tarfile.py", line 875, in open
return func(name, filemode, fileobj)
File "C:\Python23\lib\tarfile.py", line 980, in bz2open
raise ReadError, "not a bzip2 file"
tarfile.ReadError: not a bzip2 file
----
Here's the code:
----
import tarfile
from datetime import datetime

DirBackup = r'\\skpdc01\Backups'
DirOrig = r'C:\WUTemp'

NewBackupFilename = DirBackup + '\\' + '%s' % (datetime.today()) +
'.tar.bz2'
TarFileBackup = tarfile.open(NewBackupFilename, 'w:bz2')
TarFileBackup.add(DirOrig)
TarFileBackup.close()
----
What am I doing wrong? From the error message I gues the library is
expecting the bzip file to exists, but I am explicitly open it whit
'w:bz2' Any ideas?

Thanks.

Your NewBackupFilename contains ":" which is not a valid character in a
filename in Windows.

You could do something like this:[color=blue][color=green][color=darkred]
>>> NewBackupFilename = DirBackup + '\\' + '%s' %[/color][/color][/color]
str(datetime.today()).replace(':', '-') + '.tar.bz2'[color=blue][color=green][color=darkred]
>>> NewBackupFilename[/color][/color][/color]
'c:\\\\skpdc01\\\\Backups\\2005-01-21 12-26-21.373000.tar.bz2'[color=blue][color=green][color=darkred]
>>> TarFileBackup = tarfile.open(NewBackupFilename, 'w:bz2')
>>> # Works![/color][/color][/color]
I changed your DirBackup to 'C:\skpdc01\Backups'

Thanks,
