I'm not sure off hand I have a good way for it to be initialized from the server end, but if it's a backup, it might as well run on a local cron anyway rather than needing an external call. As a simple idea, cron task starts rsnapshot configured however. When this is done, backup is tarballed, and tarball is given as like, say, 440 permissions, where users are in some useful 'backup' group, then while tarball can be read to be passed across server, if tarball is extracted, user has no more privs then they have on the system anyway (I'm not saying chmod -R). Then local tarball can be removed or whatever. And call me silly for not reading documentation or assuming, but I was very happy last night when I realized system rescue CD includes rsnapshot already! ~daid
