-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I use rsnapshot at home, though I am terribly fond of it (I am better in bash than I am in perl, so hacking it up is a bit of a PITA).
What I generally do for both my servers and my clients, is that I take the initial snapshot locally, that is I bring my laptop down to their site, hook up a USB or firewire drive, and do the transfer onsite. Later I move this data to the backup server. From now on only incremental changes need to moved across the wire. For remote sites, I will manually do the first sync, usually with rsync (which is what rsnapshot actually uses). Rsync has several useful CLI flags, one of which is --bwlimit=KBPS You can do this to limit the bandwidth used to reduce the impact that the backup has. I used this to do the initial backup of a remote site in Northern Alberta. Once we had a complete copy, we started the automated backups. This does not use any less bandwidth, it just makes it less obvious. Most of the ISPs here (Shaw and Telus in particular) go after the heavy users. An rsync that takes a week at "low speed" is not usually "noticed". This is the short short overly simplified version, but you should get the idea. Hth, PS - another flexible perl backup program is backuppc. You can also do push backups with rsync, check out http://www.rsync.net/resources/howto/windows_rsync.html My affiliation with rsync.net is that of a customer, I have been extremely happy with their service (offsite backup).
