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.
I have about 750GB of irreplaceable files on my server so I want a really solid history. A couple of days backup is no where near enough to give me peace of mind 😅
3 2 1 offsite backups typically happen a lot less often than local copies or local backups.
I also don’t really consider any machines data to be irreplaceable. If I lose my phone I want the latest backup. But taxes or photos I care for? Those are an entirely different backup, and those aren’t incremental. They’re just what they are.
