The Sysadmin’s Daily Grind: Rsnapshot
The principle behind Rsnapshot is nothing new: use Rsync and SSH to back up files to another computer. What sets Rsnapshot apart is its simple setup and its rich collection of features.
Rsnapshot  gives admins a space-saving backup system. The Rsnapshot tool leaves long, configurable intervals between full backups and creates daily incremental backups on the target system; and this saves a lot of space compared to a full backup. The rotational logic that underlies the system makes heavy use of hardlinks. Under the hood, Rsnapshot uses SSH and Rsync. I decided to install the 89KB tarball on one of my lab systems, which happens to run Slackware 10, but DEB and RPM packages are available as downloads from  if you prefer. The following commands were all it took to install the Perl-based system: tar xvzpf U rsnapshot-1.1.6.tar.gz cd rsnapshot-1.1.6 ./configure --sysconfdir=/etc su make install
