You definitely should still check this, but even with proper indexing settings Windows is still garbage at search and has been since XP.

And this is coming from one of the only people who ever defends MS on Lemmy.

Yep, that would work fine for the first line of defense. Eventually, you can expand it to copy, replicate, or drive swap the onprem backups offsite somewhere (e.g., cloud, office, or family member) if you want to protect your data from site loss (e.g., house fire).

The only thing missing is a good backup.

If you are storing anything important – especially Immich and Vaultwarden data – you should have a good offsite protection strategy. And even the HASS config should be backed up with versioning because rebuilding from scratch could be painful once you get deep into it.

I’ll let others chime in on possible good backup options because I use Veeam and Azure, which really isn’t in the spirit of this community, and I’d be interested in good open source options myself.

Also, RAID (mirroring) is NOT a backup.

That just the summary aggregated from multiple sources. Below it you should be able to drill into the actual published articles.
