If you would like to give rsnapshot a try on the tablet, here was the process for installation under Diablo.

1. Install perl

Grab perl, perl-base, and perl-modules from http://repository.maemo.org/pool/diablo/free/p/perl/
dpkg -i perl_5.8.3-3osso9_armel.deb perl-modules_5.8.3-3osso9_all.deb perl-base_5.8.3-3osso9_armel.deb
(or add the diablo repo: deb http://repository.maemo.org/ diablo/sdk free non-free)

2. Install make

apt-get install make (not sure of the repo)

3. Download rsnapshot

Went for the "generic UNIX" release at http://www.rsnapshot.org/downloads/r...t-1.3.0.tar.gz

4. Follow rsnapshot directions

The rest was straightforward, using http://www.rsnapshot.org/howto/1.2/r...-HOWTO.en.html

Essentially:
./configure --sysconfdir=/etc
make install
cp /etc/rsnapshot.conf.default /etc/rsnapshot.conf


notes:
backups are saved in the /.snapshots directory
In the config file, I uncommented cmd_cp and cmd_ssh for added functionality.
The logger seems to choke on the -i option, so syslogs of backups might not be recorded
install cron for automated backups

Have fun!
