Title: Linkstations LS-CHL-V2 backup does not work if directory name contains only capital letters ?

I tried to make backups from my linkstation to attached USB drive. Basically it worked but failed to copy to those directories whose name contained only capital letters:

What was copied:

root@vpcf23l1e:/mnt/LACIE/_backups/nwhd/Pia# ls

root@vpcf23l1e:/mnt/LACIE/_backups/nwhd/Pia# ls av

root@vpcf23l1e:/mnt/LACIE/_backups/nwhd/Pia#

So the directory AV was created to the USB disk but it had name av. In the logfile then coping the files failed:

   2749 nwhd/Pia/Blurb/BookSmartData/valokuvia vuosilta 2011 - 2012/library/fef97f8c-9a85-46e5-8649-acd6995dbbcb.zoom

   2756 rsync: mkstemp "/mnt/usbdisk1/_backups/nwhd/Pia/AV/.DSC03221.JPG.rHbDRE" failed: No such file or directory (2)

Does anyone know the explanation and is there a workaround ?

This was the first trial of backup and I used Overwrite backup(Append) mode with "Create a fle folder ..." enabled. Firmware version is 1.37.

Thanks for reply !

Haven't done the upgrade yet, sorry for :-) My only explanation is that I am unsure how to be sure it is reliable after the upgrade, it so slow (for a newbie like me) to make the backups and dig out from the logs what failed, if any this time ... BTW, I'd be happy if you could still write down if you know whether upgrade helps/doesn't or if you do not know ?

Anyways, I tried to when googling rsync + capital letter I and learned that rsync (which is open source tool developed mainly to work with unix like systems ??) might have some issues with capital letters and other such things when dealing with FAT32 filesystem ( like my usb disk ).

So if problem is rsync + fat not separating capitals, does anyone have info if I need to use eg. EXT3 filesystem in the usb disk ? Then I can't use the disk with windows anymore, right ? Maybe I need to get another disk just for backups ...

Hi again !

I upgraded the sw to latest I found, 1.56. Unfortunately I looks like testing is easier than I expected, new version still cannot differenciate capital vs small letters in filenames.

I think my LinkStation has been and still is excellent product, easy to setup and has not required any maintanence for years, biggest problem so far has been you forget how to manage the thing because you dont need to :-)

And also this time the upgrade procedure was very easy and worked well, although it wouldn't have hurted to have some documents available ...

But it would be important to document these backup limitations ( at the moment I believe fat usb disk actually cannot be used as a destination of automated backup because it is quite random what gets copied and what not) should be documented clearly, now people end up into very labouros debugging work or notice that they actually do not have backups.
