All my SSH keypairs are files so they’re part of my usual backup regimen with hourly, daily and weekly filesystem snapshots, copied to several backup locations.

All my SSH keypairs are files so they’re part of my usual backup regimen with hourly, daily and weekly filesystem snapshots, copied to several backup locations.
