Re: [BackupPC-users] Compression during Xfer

rsync does provide compression. rsync -z is compressed. just put this either in your main config or in the specific hosts config for the rsync command. ssh can compress the ssh tunnel that you create.
you can also compress ipsec tunnels like openvpn or cisco vpn. Backup cant recognize it. The compression is in the transport stream, not the backup. You litterally wont be able to tell the difference in the backuppc backup.

Unfortunately, BackupPC does not support any sort of "transfer compression".
The best you can do is:
- do rsync transfers over SSH - SSH provides compression
- use VPN with compression, i.e. OpenVPN
