Re: [BackupPC-users] OT: Thoughts for "push" backup

We have already implemented such a feature. Basically, the client machine creates an ssh tunnel to connect, and then executes a command on the server to start the backup. Authentication takes place using a public/private key.
Here is the script used on the client machine: #!/bin/sh USERNAME=backuppc
PC=pc_name PORT=22000
The $PORT value is unique to each host and used in the client configuration file as the port to use for ssh
and here is the script backup.sh used on the server:
#!/bin/sh PC=$1 USER=$2
sudo -u backuppc /usr/local/bin/backup.sh $PC $USER
A similar script can be organised on windows using putty.
I don't think this is a "dirty hack", there is no other option than to have rsync installed on the client machine.
I hope that helps
R.

No VPN is a big limitation. You really don't want your backup server to
be accessible over the Internet.
You might consider Deja-Dup. It backs up to cloud storage, but it uses
compression and encryption when doing so. The storage provider cannot
access the data.
