Right now I’m creating a nightly restic snapshot of my server on borgbase and on some spare drives, and keeping the snapshots forever. There’s a ton of daily churn in my data though, between databases and logs and other files that don’t constitute ‘real data’ but might be needed to restore the app.
Still don’t consider it a proper back up personally.
It’s just not a good long term solution. A short term backup for redundancy while actively working on something sure. Just keep it local.
But as a real actual backup? No, local doesn’t cut it.
