I'm coming to the end of my tether with my crappy Linkstation's refusal to work with OSX files.
The unit is set to do a weekly back up (incremental, adding new files and not deleting anything) to a 1.5Tb drive which is plugged into the NAS. This worked perfectly for 12 months, then I got a macbook and something went wrong.
The backup proceeds ok, then the setup page says "an error occurred during backup". The error in the log is always along the lines of:
rsync: cannot stat destination "/mnt/usbdisk1/_backups": Input/output error (5)
rsync error: errors selecting input/output files, dirs (code 3) at main.c(493) [receiver=2.6.8]
rsync: connection unexpectedly closed (8 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(463)
Previously, I could go in a reset the backups and it would come up with the same error but did appear to have done the backup properly. But that was a manual backup, which it should be automatic. As well as the above errors, it invariable fails on the hidden osx files.
This weekend I reformatted the USB drive as FAT32 (it was previously XFS) and set the backup off again. Now this time it won't even complete the initial, full backup.
This set-up is completely useless for me. I deliberately chose a NAS that would back itself up to an external drive, to protect against drive failure and accidetal deletion. Now it's not doing it at all.
Does anyone have any ideas as to what's going wrong and how I can get the drive to do what it's supposed to? I've had long email chats with Buffalo support, who didn't give me any indication that they even understood what the error log was saying...
