I try to rsync the drive to my homebuilt NAS any time I add photos. At this point I feel comfortable formatting SD cards.
The NAS is set to backup to Backblaze using restic every night at 3am.
I'd like to add one more backup into the mix, but cloud storage is expensive.
I'm now using an OWC Envoy Express Thunderbolt 3 enclosure with a 4 TB WD Black SN850X and have no issues whatsoever. Very happy with this solution!

There are other approaches, but I appreciate having the dedupe & snapshots, and I encrypt any potentially sensitive files that I send to the cloud.
