I have seen it happen on a couple of occasions where a Windows machine (backed up via Cygwin rsyncd, not the minimal rsyncd off the SF page) will suddenly stop working for incremental backups. Full backups will continue to work, but incrementals will start failing with a PIPE error. For example, here's a run where I was trying to debug with '/usr/share/backuppc/bin/BackupPC_dump -i -v host.example.com':
create d 770 544/1049089 0 Program Files (x86)/Common Files/Adobe/AAMUpdaterInventory/1.0/AdobeIDCC2015AppLangen_US-11.0 create d 770 544/1049089 0 Program Files (x86)/Common Files/Adobe/AAMUpdaterInventory/1.0/AdobeIDCC2015AppLangen_US-11.0/11.2.0.100 Done: 0 files, 0 bytes Got fatal error during xfer (aborted by signal=PIPE) Backup aborted by user signal dump failed: aborted by signal=PIPE On the rsyncd side, the rsyncd.log says: 2016/06/09 11:26:23 [1728] connect from backuppc.example.com (10.77.87.121) 2016/06/09 11:26:23 [1728] rsync on . from [email protected] (10.77.87.121) 2016/06/09 11:26:23 [1728] building file list 2016/06/09 11:30:25 [1728] rsync: [sender] write error: Broken pipe (32) 2016/06/09 11:30:25 [1728] rsync error: error in socket IO (code 10) at io.c(820) [sender=3.1.2] A run with '/usr/share/backuppc/bin/BackupPC_dump -f -v host.example.com' will run to completion, but the incremental fails, even if it's run soon after a full is run. I've tried updating cygwin, and the rsyncd package was updated. The fact that I was able to upgrade a very large number of packages in the cygwin installation, indicates to me that it wasn't a cygwin upgrade which broke things. This only happens to an occasional Windows machine, and it happens without any obvious cause. Not all Windows machines will break, just one. Any suggestions on how to debug/fix this? the obvious workaround is just to only do full backups, and I've done that in the past, but if I can solve this a better way I'd like to do so. The next step would be to uninstall and reinstall cygwin. It's possible the problem is some corruption in a file which hasn't been upgraded and thus repaired. -- Carl Soderstrom Systems Administrator Real-Time Enterprises www.real-time.com ------------------------------------------------------------------------------ What NetFlow Analyzer can do for you?
