I'm looking for a way to keep two external drives synchronized. I have Drive 1 that I want to use when I'm away, and Drive 2 at home that I would like to mirror Drive 1 in real-time. However, when I return home after a trip, I want Drive 2 to copy over the files or changes I made while I was away. I've heard that RAID 1 doesn't work for this as it can lead to data corruption. What would be the best solution for this setup?

Mirroring isn't a good fit for what you're describing since it requires both drives to have the same content all the time. You'd benefit more from folder synchronization or backup management software.
For syncing purposes, I recommend using SyncBackPro. I've been using it for years to manage identical external drives, and it works like a charm.
You don't actually want to mirror your drives. Instead, what you need is a syncing solution. Just set it up to sync when you reconnect your drive after being away.
If you're looking for a free option, try Rsync. Set it up in a batch file to run every hour or so. It'll only copy what’s changed, so it’s quick and efficient!
