Error compressing tar file

[Mike]

Hello,
I have the script that make a backup file (this process is ok), but now i wish compress the file on tar file format. But i have problem syntax in the line of the tar function.

The error is

[root@master ~]# python bkp_db.py
File "bkp_db.py", line 19
tar = tarfile.open(dumpfile)+'.tar.gz','w:gz')
^

Note: The 'dumpfile' is the variable for my dump generate with format db_02-27-14

.......
tar = tarfile.open(dumpfile)+'.tar.gz','w:gz')
tar.add(os.path.join(dumpfile), arcname=dumpfile)
tar.close()
.........

Wath is the correct sintax?


Thanks.

Hello,
without ")" i have the same sintax error:

[root@master ~]# python bkp_db.py
Traceback (most recent call last):
File "bkp_db.py", line 19, in <module>
tar = tarfile.open(dumpfile + '.tar.gz','w:gz')
TypeError: unsupported operand type(s) for +: 'file' and 'str'

Thanks.

That is not a syntax error. It is a type error. You cannot add a file
object and a string object together.

Please inspect the value of dumpfile. You are treating it as if it were a
string, but it looks like it is an open file object. I think that you
probably expect this:

dumpfile = "path to some file"
tarfile.open(dumpfile + '.tar.gz','w:gz')


but what you actually have is probably something like this:


dumpfile = open("path to some file")
tarfile.open(dumpfile + '.tar.gz','w:gz')
