I moved from my own colocated 1U running Mailcow to Fastmail and don't regret it one bit. This was an interesting read, glad to see they think things through nice and carefully.

The only things I wish FM had are all software:

1. A takeout-style API to let me grab a complete snapshot once a week with one call

2. The ability to be an IdP for Tailscale.

1. hoping to have a JMAP archive format at some point which should cover that. I'd hope that normally you'd be fetching a delta update rather than the whole thing. We've got enough bandwidth for a few people do to it, but I wouldn't want every customer pulling their entire archive every week of 99% the same immutable data; that would be kinda sucky.

2. yeah, I'd love that too - we're keen to integrate with everything else that people are using. We have a basic in-house IdP thing for our own staff to authenticate against our hosted services, but haven't scaled it out. This will happen eventually, though I've been burned enough times I don't want to promise a timeframe.

When I back up machines I only pull a full backup 3-4 times a year and then I stack weekly deltas on top of those.

I'd start with that and see how it seemed to work when trying to look through backups and test-restore things.
