Backup over the wire

[girarde]

Because USB3 is just Taking Too Long, I built a backup server to back up to over the wire, and this is well. I'm using dump(8) and ssh(1) to do this, and it's OK.

What might be OKer would be the backlup server knew the schedule and woke up workstation(s) to be backed up, did backups, and shut them down if they weren't already running at backup time, and itself down in any case. I believe this could be done with a backup user in the operator group, but I have slight heebie jeebies about passwordless private keys to avoid computers wanting me to type at 0300 local.

What you say you, Knights of the Pufferfish?

Consider cron(8) jobs on the workstations to initiate backups, or perhaps initiating from daily / weekly / monthly .local files per daily(8). You can control the capability of the specific user logging in with a passphrase-less key, via sshd_config(5) Match rules, such as with ForceCommand, ChrootDirectory, and internal-sftp.

(I used to use dump and restore via ssh, but switched serveral years ago to Tarsnap, a commercial service.)
