For backing up a laptop locally, bacula seems to be HUGE
overkill. How long will you be keeping these backups? How many
backups will you be keeping? My guess is that you'd be better
served by a little scripting, rsync and cron.
Each day, establish a new directory by date, then hourly run rsync
to that location.
Or, Each day establish a new directory by date, create
a "watcher" file, then hourly run a 'find [dir] -newer
/path/to/watcher' to establish a list of files which have
changed, then 'touch /path/to/watcher'. From the list of
files which changed, tar them to backup location.
Depending on how you want to keep files, you'll either have
a date directory (/backups/20090527) with all of the days
changed files in it, or you'll have a date directory with hourly
subdirs with the hourly changes (/backups/20090527/01, etc.).
Then, when you're back at the office, where the bacula server
is, you kick off a backup manually which will backup your
/backups directory.
