[NMLUG] Linus would call it "bad taste".
I only skimmed your backup script, but here are some random thoughts:
% You might consider something like:
/bin/tar --bzip -cvf /backup/backup.`date +%Y%m%d`.tbz list-of-dirs
/bin/rm `find /backup -name 'backup.*' -mtime +5`
(probably needs to be tweaked for your system), assuming you can find a
"bunzip2" program for Windows.
% For reference, you can use "split" to split large files into smaller
chunks, but this won't necessarily help w/ Winzip (because splitting a
compressed file into pieces does NOT create several compressed files), but
you might be able to use it as part of a pipe-line (eg "tar | split |
bzip" or something) to help?
% Maybe keep /mnt/smb permenantly mounted?
% By default, cron will email you the output of cron jobs, and this email
could be used as your "log file"?
