[Snapshot Pro] Skip big files/folders in backups

1. Some websites have huge download archives or a folder full of mp3s (eg podcasts sites). It would save a lot of bandwidth, space and cpu power if we could filter the files/folders. Filtered files/folders should be skipped during backup resulting in smaller backups.

2. If Automate is active there are numerous backups which are “useless” because there will be several full site backups for one day. Nearly everyday is an update available making some backups redudant. It would be really nice if Managed Backups would recognize backups from Automate to save storage.
