links broken during a backup (not restore), need more info on how they work to fix & file bug with vendor


Hi,

I believe my backup program (CMS ABS Bounceback) is mucking with the links in my cygwin and work directories when it is creating a backup.  It doesn't appear to affect links created by windows, only those created by cygwin.  I don't fully understand the cygwin links: there are some that end in .lnk and are close to windows shortcuts, and there are others that don't end in .lnk and start with !<symlink>.  Both get broken.  The files still exist, but I get the message "/usr/bin/vi: /usr/bin/vi: cannot execute binary file".  vi looks like a plain file and contains "!<symlink>vim.exe".  Running vim works fine.

It happened to me a few weeks ago and wasn't sure why.  I re-installed cygwin & fixed all the shortcuts in my working/compiled src directories by deleting and recreating them.  Is there an easier way to fix this?  I found one post in the archives saying try "attrib +R", but that didn't help at all, on either kind of link.

I've searched the mailing lists and google and wasn't able to find any help for my problem.   I know people here will say it's a problem with the application, but if I go to the manufacturer they'll say cyg-what(?), our software works fine with windows.


Some sample links in /bin, commands executed under cygwin on windows xp.

$ ls -la vi ksh.exe.*
-rwx------+ 1 usd11620 memememe  319 Apr 18 10:24 ksh.exe.lnk
-rwx------+ 1 usd11620 Users     18 Apr 18 08:12 vi

$ attrib ksh.exe.*   
           C:\cygwin\bin\ksh.exe.lnk

$ attrib vi       
           C:\cygwin\bin\vi

$ cat vi 
!<symlink>vim.exe

$ ksh
bash: ksh: command not found

$ ksh.exe.lnk
/usr/bin/ksh.exe.lnk: /usr/bin/ksh.exe.lnk: cannot execute binary file

$ cat /usr/bin/ksh.exe.lnk | tr -c "[:print:]" .
