Not sure whether you're a Construction package or a Hospitality one? Tell us what you do and at what scale — we'll point at the package that fits, with the reasoning.
Note: Packaged trade tiers include a local PostgreSQL dump every night at 02:30, a separate off-site copy every day at 03:30 held with a different provider, write-ahead-log archiving for local point-in-time recovery, and UK accounting. Replication to the standby is asynchronous today, with synchronous mode in preparation, so work committed in the last seconds before a failure may not have reached it. Failover is operator-assisted throughout: a human decides and switches, so expect minutes, not seconds. The standby toggle mostly matters at the top of a package's headroom, where the capacity has to scale up.
