Comment 1 Barry Sanford 2014-06-22 14:38:18 UTC
I have a server on my LAN that's hosting an rsync daemon.  When I backup to the 'Backups' module on this server I have a 'pre-exec' script that creates a 'HardLink' file.  Then a 'post-exec' script deletes this file.  After running a backup, I get the following when I list the contents of the server's folder:

$ ssh server.local ls -l /Volumes/Rugged/Backups/EBSMac
total 8
drwx------  9 ebsanford  staff   306 Jun 21 23:58 20140621
drwx------  9 ebsanford  staff   306 Jun 22 00:00 20140622
-rw-------  1 ebsanford  staff  1309 Jun 22 09:15 LOG


$ rsync server.local:/Volumes/Rugged/Backups/EBSMac/

Notice in the 3rd listing that the 'HardLink' file is still present!!! I believe this to be fantom lurking around in a cache somewhere.  Restarting the server rsync daemon does not clear the issue.
Comment 2 Barry Sanford 2014-06-22 14:46:51 UTC
Btw, the HardLink file is created by the pre-exec script as a symbolic link to the previous day's backup folder.  For example, if the current backup folder is 201406022, then the pre-exec script will create the HardLink file as:

    cd .../$RSYNC_HOST_NAME
    ln -s 20140621 HardLink

It is freshly present, having been created by the pre-xfer exec function (since you used the daemon for the listing).  Thus, it is working exactly as expected.
Comment 4 Barry Sanford 2014-06-22 17:45:57 UTC
Ahhh!!!  The fault, then, is in my own understanding, or lack thereof.  I was under the false assumption that the pre-exec ran only when files were being copied.  But now my understanding is that the scripts run each time the module is accessed by the daemon--correct?

Wayne, thanks for your speedy reply!!
