My Linkstation LS-QL/R5 was finally set up and receiving RSYNC'd copies over the Internet via SSH tunnel. I thought all was working great until I tried doing a differential backup. The LS is mounted on my Linux machine and I have a script which writes the contents of the LS onto a robotic DLT device. The differential backup checks for newer files than the last full backup but stumbled when it came across a directory named XXXX Hill Fire Dept (XXXX is not real name). The problem was there was a strange character after Dept. I was able to rename the folder on the system across the Internet but when I rsync with the --delete option the bad folder name was NOT removed. 
Not sure if the image will display, getting strange indicator that image not there.
I am trying to exclude copying the bad name using rsync locally as moving 50 plus gigabytes over the internet takes a full day. I don't want to have to delete everything and start over. I really need a way to delete just the bad folder.
UPDATE Nov 22, 2010: I copied the contents of the folder (excluding the one with bad character) to another folder so I know the --exclude command will get me out of copying everything over the Internet. I have created another folder via the web interface called Backups. and have spent the last 12 hours rsync'ing from the original folder to the new Backups folder. I know the user doesn't know enough about computers to not do this again so I REALLY need a solution from Buffalo on deleting or renaming a folder (or file for that matter) that has an invalid character in it.
More than 2 years later and no comments on this problem. I have more files that I can not delete with Windows explorer, DOS, Linux. The files on the remote system have long been deleted and when rsync runs it can't delete the files on the Linkstation Quad. Last time I initialized the drive but it took days to recover. Does anyone from Buffalo look at this forum?
