Oooh. Hadn't even thought about doing gpg on the files prior to transmission. Awesome idea. The side benefit of doing it that way is that I can have clients off-site that have the key, but I do not. I can back up their data, they can restore it, all the while I don't have access to their fi

I think it would be better to change the ping command to the arpping command. This way you can block ping requests on the clients (which is safer), and backuppc is still able to check if the pc is alive or not. It must be said then that backuppc must have access to the arpping command which is ge

On linux, this model would use the dm-interface. This could be for example to create a LUKS encrypted partition. It would - per design - not protect from an on-line attack with admin rights however. /johan Tony Shadwick wrote: > Rsync it to a mac, keep it on a filevaulted volume. That would d

Hi! This is an interesting scenario. I don't think I've seen it before. I've created a system to proxy data on an untrusted network but not with change tracking. One short comment first: with rsync over SSH (normal, non-daemon operation) you won't need a VPN. At the end of this document is a "

Rsync it to a mac, keep it on a filevaulted volume. That would do it. :) FreeBSD has md (memory disk), and you could probably format it with an encrypted filesystem. Not sure what to tell you so far as Linux goes. Kris Jordan wrote: > I'd like to make an off-site backup of my BackupPC data par
