Re: [BackupPC-users] Pre-populate backups? Only incremental?

[Rob O. <ro...@bi...>]

1) I've successfully "pre-populated" backups in the following way.

a) Configure backuppc to backup my host machine (myhost.com) over the
internet.
b) Take my host machine (myhost.com) and physically place it on the same
local network as my BackupPC server.
c) Determine the local IP address of the host machine (lets say it's
192.168.1.100)
d) Edit /etc/hosts on the BackupPC machine to include the following line:
192.168.1.100	myhost.com

This "tricks" the BackupPC machine into looking on the local network for
myhost.com

2) For remote backups, you should probably use rsync or rsyncd as your
transport.  That way only the changes are transferred, even with "full"
backups.  "Full" to rsync only means that it does extra checking of the
files.  Specifically, it uses the --ignore-times option.  So to be
clear, using rsync or rsyncd you will need to transfer the entire backup
only once.

Search the archives for "rsync incremental-only backups for eternity" in
July of 2007.
