Backup Central

Hello,

I just learned about and installed rdiff-backup yesterday. I tried to
run the command:

sudo rdiff-backup -v4 --exclude /dev --exclude /tmp --exclude /Volumes
--exclude /.Spotlight-V100 --exclude /automount --exclude /private/tmp
--exclude /Network --exclude /private/var/run / /Volumes/Mirror

and this is the output I received after it ran for a while (it copied
nearly 9 GB before halting):

I assume you are running Mac OS X? It seems to be a problem with the
error-checking in the carbonfile code, but I'm not 100% sure since I
don't have any experience with that OS.

To whoever (John Goerzen?) wrote the get_carbonfile() function: maybe
it shouldn't catch the MacOS.error exception? It seems like it
catches it, and returns a bad cfile which write_carbonfile chokes on.

It seems that with OS X 10.4 you need to use two switches:

--no-carbonfile --override-chars-to-quote ''

The second switch ends with two single quote characters. It might
only be necessary if you are backing up to and from the native HFS+
file system.

What if you add this patch:

--- rpath.py 2005-09-07 12:04:37.000000000 -0500
+++ rpath.py.new 2005-10-15 21:48:04.000000000 -0500

def write_carbonfile(self, cfile):
"""Write new carbon data to self."""
+ if not cfile: return
log.Log("Writing carbon data to %s" % (self.index,), 7)
from Carbon.File import FSSpec
import MacOS

Do you still need to add --no-carbonfile, or does that fix that
problem?

This patch seems to stop the crash. I did an incremental backup, and
now I get a bunch of UpdateErrors like this:

UpdateError Desktop/RV_Stuff/POH archive/graphs/all-3.gp Updated
mirror temp file /Volumes/Ext_BU/Users/kwh/rdiffbu/Desktop/RV_Stuff/
POH archive/graphs/rdiff-backup.tmp.7305 does not match source

The file listed in the first of these UpdateErrors was the one that
was causing the crash before I started using the --no-carbonfile
flag. I assume the backed up file would have included the carbonfile
data if that flag had not been used, and this is why rdiff-backup is
now complaining about the file not matching the source. Does this
make sense?
