Hello, 

Hopefully someone can help me out with this. I've looked this error up and came 
across this old posting: 
http://adsm.org/lists/html/BackupPC-users/2009-08/msg00115.html

However there was no luck there as it seems my issue may be different. What 
I've observed is that I receive this error in the log file for every host I 
backup. 

After some investigation I believe this to be related to symbolic links. When I 
check the symbolic links are not in the "f" directories. Here is an example: 

2014-09-25 08:47:10 BackupPC_link got error -3 when calling 
MakeFileLink(/var/lib/backuppc/pc/pfy.res.oicr.on.ca/0/f%2f/fsbin/flvchange, 
adcd7bc3e2583e93ed4e4a0e7ae055d1, 1)

Checking for the file, it is not there. 

backuppc@backstage:~/pc/pfy.res.oicr.on.ca/0/f%2f/fsbin$ ls -lh | grep change
backuppc@backstage:~/pc/pfy.res.oicr.on.ca/0/f%2f/fsbin$

and checking on the host it's a symbolic link 

pfy:/sbin
$ ls -lh | grep change
lrwxrwxrwx 1 root root      3 Jan 27  2014 lvchange -> lvm


when I check in the backuppc webpage for the host, and browse directory 'sbin' 
I don't see this symbolic link there, however I do see other 'symlinks' 
mentioned. (For example /sbin/stop)

Here is the log file for those two: 

backuppc@backstage:~/pc/pfy.res.oicr.on.ca$ BackupPC_zcat XferLOG.0.z  | grep 
sbin/stop
  pool   l 777       0/0           7 sbin/stop -> initctl
backuppc@backstage:~/pc/pfy.res.oicr.on.ca$ BackupPC_zcat XferLOG.0.z  | grep 
sbin/lvchange
  create l 777       0/0           3 sbin/lvchange -> lvm

I checked the log and the xfer log for this host and its accurate to say that 
all the files that got the -3 error are all set to "create" instead of pool. 

This host was new and this was the first backup being done, so I would assume 
"pool" means that file already exists somewhere in its pool so it will just 
link to it for this host and "l" being symlink.  So the problem here is why are 
new "create" for symbolic links failing? 

Thanks,
