Symbolic link problems
1997-03-04 19:56:49
Hi Trevor,
I tried to recreate the symbolic link problem you outlined. As you can
see from the output below, the symbolic link "linktonothing -> /fresh/air"
was correctly restored in my testcase. I do not understand the difference
I ran it on an AIX 4.1.4 workstation. You might want to take it up with
level2 support.
We are looking at backing up and restoring device special files. My
understanding
is that not all versions of UNIX support files of type socket. What type of
system are you using? How did you create this type of file? Is it important
to back it up and restore it.
Also, do you ever use ACLs on special files? I presume for none of these
should we back up data. Is that correct? Thanks for any input. John Viksne
