Re: [BackupPC-users] OSX extended atribute problems

[Brien Dieterle]

The ".filename" stuff is called AppleDouble and I think it preserves metadata as well in there. Are you also getting a ton of xfer errors as below? (I did) /usr/bin/tar: /tmp/tar.md.Fif1QE: Cannot stat: No such file or directory /usr/bin/tar: /tmp/tar.md.b7XePQ: Cannot stat: No such file or directory /usr/bin/tar: /tmp/tar.md.QMKDdp: Cannot stat: No such file or directory I decided the extended attributes were not really necessary for disaster recovery and I found you can turn them off via an env variable: $Conf{TarClientCmd} = '$sshPath -q -x -n -l root $host' . ' /usr/bin/env LC_ALL=C COPY_EXTENDED_ATTRIBUTES_DISABLE=true $tarPath -c -v -f - -C $shareName+' . ' --totals' . ' --one-file-system'; That cleared up all my tar xfer errors on 10.4 brien John Pettitt wrote: I'm running 3.0.0 and noticed that Mac OSX clients take way longer to do an incremental backup that I would expect given how many files have changed.    I dug around in the logs and found that tar on the mac copies extended attributes as ._filename files and totally ignores the --newer flag when doing so.   The means that all extended attributes are copied every time.       Further research shows that extended attributes don't actually have any timestamp and apple tar just assumes the current time. Does anybody have a work around for this?    Unfortunately rsync is not an option because it doesn't store extended attributes at all (the apple -E flag just causes backuppc to hang). john ------------------------------------------------------------------------- Take Surveys.
