Can we absolutely rely on Snapshot backup?

Valued Support Team,

tonight it's our first time we are using SNAPSHOT PRO. Setup and determine settings are obviously simple (thanks to explanation in existing manual too).

However we are wondering, does this backup / restore feature also consider to save ALL databases which we have setup in our MULTI-DB configuration? Can we really relay on 100% accuracy?

When restoring a backup, do we have to do extra steps regards our multi-db's?

Looking forward hearing from you soon.
Kind regards
