Problems backing up to Linkstation from Mac
I've been lurking on this group for a while, but haven't done any of
the mods suggested by this group (yet). My key issue is backing up to
my Buffalo Linkstation from a Mac (OS X, version 10.4.9).
I want to backup my iTunes Music collection to the Linkstation (~
40GB). I'd like to have access to the individual music files, rather
than backing up to a special archive. I use Retrospect for my
backups, and it has a duplicate feature which is just what I want,
including doing incremental backups of any changes (e.g. additions to
my iTunes collection).
I've tried backingup up to the Linkstation both as an Apple share
(AFP) and as a PC share (SMB), and both of them have problems,
although they are completely different.
It seems that the Linkstation has an old version of the AFP protocol
that only allows short file names (< 32 chars) and limitations on
filename characters. Many of my iTunes song names are long or have
special characters, so this just doesn't work.
When I mount the Linkstation as a PC share, I have a different
problem. In this case, I can do the duplicate, but on about half of
my files I get an error like:
File "103.1.mp3": different modification date/time (src: 3/6/2003
4:38:19 PM, dest: 3/6/2003 4:38:18 PM), path: "temp/103.1.mp3".
Where the modification date/time is off by 1 second. In researching
this, I believe the Buffalo Linkstation NAS drive is running Linux,
with a SAMBA server and the SAMBA server has a configuration to always
round the seconds of the modificaiton date/time to an even number of
seconds. The config option is called "dos filetime resolution".
So, about half my files have a time ending in an odd number of
seconds, which is rounded down to an even number of seconds on the PC
share. So, when checking if the copy was okay, Retrospect reports an
error on these files. But, what's worse is that if I go to do an
incremental backup, Retrospect will try to copy those files (half of
40GB) over again, since they have different last modification time
(off by 1 second). Since this is about 20GB, it takes a long time,
even though I'm only trying to do an incremental backup of say 200MB.
BTW, I believe I have a "Linkstation Gigabit", or an HD-HGLAN model
(HD-HG400LAN to be exact). I've never gotten telnet access to the
device (which seems to be the assumed first step for getting root
access). I was running firmware 1.42, but just upgraded to 1.61.
Thanks in advance,
