Backup fails because there is a period (".") at the end of my filename.

Hi, I'm trying to setup a backup on my new ReadyNAS 212 (Firmware 6.7.5). Whenever I run the backup I receive an error : Cannot read file 'opti/makeinclude/shared.mk.' (error: No such file or d...

You could of course use a different backup protocol (NFS or RSYNC).

Thanks JennC.
It is a text file. Once I changed the filename, it worked fine.

Yes, I was using the Backup Job from the admin page.

But the file was actually created/copied from a linux machine. So that may have something to do with the syntax of the filename.

Win7, will not let me create a file with a trailing "." (period). I'm not sure how you were able to create your "testfile.she.".(?)

Hello Phil140,

I used 2 different computers, Win10 and Win7, I was able to create a file with a "." in the end of the file name. I think you should not do it on Linux as Linux may read the word after the "." as filename extension.

Thanks JennC.
I have a suspicion that Windows is playing a trick on you. What you see on file explorer window is, in reality, named "testfile.she..txt" on disk.
You might need to use the option on windows explorer to display the file type.

When I refer to a "filename" I am implying the filename+filetype. (Sorry for the confusion.)

  Hello Phil140,
  
  The file that has "." also shows on the admin page when browsing the share that was set as destination on the backup job.
  
  I also enabled HTTP access for that share and it also shows there.

    Hi JennC,
    I'm sorry. I'm not really able to understand the confusion.
    
    I did another test. This is what I did...
    1) From windows, I created a file "testfile..she" with no period at the end, but two periods in the middle.
    2) From linux, in the same directory, I generated a file that has a period on the end of the filename (ie. after the '.she').
    
    touch testfile.she.
    
    Then I waited for the incremental backup to run.
    Then I went to the ReadyNAS and accessed it via telnet, and looked at the backup folder.
    This is what I found:
    
    $ ls -al | grep testfile -rwxr-xr-x+ 1 root root 0 Jul 13 18:18 testfile.she..txt $
    As you can see, the file "testfile.she..txt" is there as expected. That works.
    
    However, the file "testfile.she." is not there. That is not good.
    
    I don't see any errors in the log file this time, perhaps because it was an incremental backup.
    
    For now, I won't be concerned about it. But it is a bit alarming that some of my files are not being backed up.
    
    Thanks for your help. Maybe it's a problem with CIFS and netgear is unable to do anything about it.
    If that is the case, I understand.
