All not working so when when working with the next HDD backup:
rsync -vain --prune-empty-dirs --delete \
--include='[T-Z]*' --include='*/' --exclude='*' \
When run without the --prune-empty-dirs it picked up a directory starting
with iZ, but didn't list the sub-directory and its files. With the
--prune-empty-dirs, it was no longer listed. It should never have been listed
in the first place as I never included "i". But, worse than that, the
--include='*/' is causing ALL directories in /share/Public/videos/ to be
queued up for transfer to the backup HDD.
The filter rule is not working out in practice. For example, the following
directories do not get copied:
Why? Because the "S" in Season is getting excluded because it is not in
the initial include rule.
How do you get the filter rule to only look at the first part of the path
and ignore the remaining part of the path?
The man page for Filter RULES has the following:
As the list of files/directories to transfer is built, rsync checks
each name to be transferred against the list of include/exclude pat‐
terns in turn, and the first matching pattern is acted on: if it is an
exclude pattern, then that file is skipped; if it is an include pattern
then that filename is not skipped; if no matching pattern is found,
then the filename is not skipped.
That tells me that the first rule I have "--include='[T-Z]*'" says that
Victoria/Season-1 and all its contents should be copied. But, it is checking
again after the "/", thereby excluding the directory. :-(
Looking further at INCLUDE/EXCLUDE PATTERN RULES, I found the following:
o a trailing "dir_name/***" will match both the directory (as if
"dir_name/" had been specified) and everything in the directory
(as if "dir_name/**" had been specified). This behavior was
added in version 2.6.7.
So, changing "--include='[T-Z]*'" to "--include='[T-Z]*/***'" seems to have
done the trick (of course removing the "--include='*/'").
This has been a real brain teaser.
