rsync --delete question
 

This deletes files only in the DESTINATION right? I just want to make sure! My command is:

rsync -vrbu --delete ${mount_path} ${backup_dest}

Just want to make sure, since it has write access to both paths and I would not want a disaster that I only notice later on.

Yep, that deletes files on the receiving side that don't exist on the sending side
I use --delete-after but that's just my preference.

--delete delete files that don't exist on the sending side
--delete-before receiver deletes before transfer (default)
--delete-during receiver deletes during transfer, not before
--delete-after receiver deletes after transfer, not before

Oh ok, so delete-after makes sure the transfer finished, I might want to go do that too then.
