Hello list, I'm posting some info here hoping it might help some others. I searched around a bit before I guessed (correctly) at the cause of my problem. I'm currently using cwrsync (rsync 2.6.2) to backup data from a Windows XP machine to a Windows 2000 machine. Unfortunately the boss won't let me use Linux here. My process worked fine for at least a month but recently had started to refuse to automatically delete anything on the destination drive. The command I am now running is: rsync -av --delete --exclude=RECYCLED --exclude=RECYCLER --exclude="System Volume Information" --exclude="big.zip" 192.168.1.21::buffalo160 /cygdrive/f/ >> c:/logs/cwrsync/stdout.txt The only reason I noticed that it had stopped deleting files was the error at the top of the stdout log. With two -v flags it read: opening tcp connection to 192.168.1.21 port 873 receiving file list ... [receiver] expand file_list to 131072 bytes, did move done IO error encountered - skipping file deletion delta transmission enabled ... I was mystified as to what had changed that was preventing files from being deleted (I still don't know. Maybe a change from FAT32 to NTFS?). More annoying was the fact that my log wasn't telling me the cause of the IO error. The most common IO erorrs experienced by rsync using people seemed to be permissions related, but I didn't want to change the permissions on the 2,000+ files on that drive. Eventually I discovered that the sending machine also keeps a log (if you instruct it to do so in rsyncd.conf) and this log led me to the problem: I needed to add "RECYCLER" to my list of files to exclude. Now my rsync happily deletes and my hair has begun growing with redoubled vigor! Thank you cwrsync! --Jacob Levine
