can i create a filter that match with “not contains” rules?

i would to create a filter that move to folder “Archive” all email that not contains word “backup” in subject.

in other words, only mail with contains “backup” rest in INBOX.

Thank you in advance


I would probably be looking at the regular expression options. I don’t have one for you, though, sorry.
