Is it possible to set up a directive that would skip everything

but .html files anywhere they exist?
NetWorker's directives seem to be based on what to exclude, not what to
include. Too bad you can't go the other way or use wild cards with save
sets? Any possible way to use 'ignore' or 'forget' here? I can't think
of one that would accomplish this.
From the uasm(1m) man page:
Note that once different modes are set, the only way to turn them
off is to explicitly match an ASM directive for uasm.
The way they word it makes it a little ambiguous. I never thought about
using 'uasm' itself in a directive. Also, the man page mentions:
Walking ASMs traverse directory trees. The skip, null, and nullasm ASMs
do not walk.
Does that mean that it will not descend?
I'd try something like this:
null: * .?*
uasm: *.html
I experimented with this by creating various '.html' files under the
/data/dir1 directory and then running 'savegrp -n -l incr groupname'
from the primary backup server to test to see how much would be
reported. The '.html' files were large enough to generate reliable
numbers. The results indicate that only '.html' files that exist at the
top level of the directory will be captured, none further down.
However, in order to get this to work even just for the top level it was
necessary to either specify '+null: * .?*' or list the 'uasm: *.html'
line first, before 'null: * .?*'. Otherwise, it doesn't even get the
ones at the root level of the directory. I tried with both a '.nsr' file
under the directory itself as:
+null: * .?*
uasm: *.html
and one at the level just above it as:
<< dir1 >>
+null: * .?*
uasm: *.html
I have a directory (/data/dir1), and the only thing that will get
updated might be some .html files. Everything else can be skipped.
If it's only one directory (and not subdirectories) you could use skip
instead of null. But I'm afraid skip will stop descending directories,
so you couldn't see html files at lower levels. That's just a guess
though. I haven't played with how they descend in a while.
