Get python tarfile to skip files without read permission
- by chris
I'm trying to write a function that backs up a directory with files of different permission to an archive on Windows XP. I'm using the tarfile module to tar the directory. Currently as soon as the program encounters a file that does not have read permissions, it stops giving the error: IOError: [Errno 13] Permission denied: 'path to file'. I would like it to instead just skip over the files it cannot read rather than end the tar operation. This is the code I am using now:
def compressTar():
"""Build and gzip the tar archive."""
folder = 'C:\\Documents and Settings'
tar = tarfile.open ("C:\\WINDOWS\\Program\\archive.tar.gz", "w:gz")
try:
print "Attempting to build a backup archive"
tar.add(folder)
except:
print "Permission denied attempting to create a backup archive"
print "Building a limited archive conatining files with read permissions."
for root, dirs, files in os.walk(folder):
for f in files:
tar.add(os.path.join(root, f))
for d in dirs:
tar.add(os.path.join(root, d))
