I understand. However, I can't think of a better way to do what you
want than what I already suggested. The issue is how to record when a
file was deleted from the source so that it can be deleted from the
destination two weeks later.
It would be possible to use --delete --max-delete=0, save the itemize
output to a file, and write a script to parse it two weeks later and
actually carry out the deletions. However, it seems easier to me to
keep the destination identical to the source and use -b --backup-dir to
move the deleted files to a separate "backup dir" on the destination.
Then you just delete each backup dir two weeks after it is created.
If you want a view of the source including the recently deleted files,
you can easily generate one from the identical copy and the backup dir
series using another rsync command, something like this:
sources=(src-ident/ $(ls -rd backup-*/))
rsync -a --delete "[EMAIL PROTECTED]/#/--link-dest=../}" \
"[EMAIL PROTECTED]" src-all/
Here src-ident/ contains the identical copy, backup-YYYY-MM-DD/ is the
backup dir for that date, we assume backup dirs older than two weeks
have already been deleted, and the combined view goes to src-all/ .
