[Dirvish] Exclude backup from dirvish-expire

[hanj]

Hello All

I currently have a backup set (5+ weeks) of two server images. I'm no longer backing them up, so I removed these two from runall. But I want to keep the current backups in the bank, but not have them removed when expire is run. Is there a way to exclude a vault when dirvish-expire is called? I have 8 other vaults that I do not want to change the behaviour.

Thanks!
