So essentially you're asking "How much backup can I get on 512 MB?"
Totally depends of course on the amount of data you are backing up.

ofcourse can hdup do this :-) But more serieus. If you can get 1 month
of backups on 512 MB, you're done. If not: you must run hdup more often,
i.e once a week a full dump (called monthly in hdup speak). And then
write week-cd's (containing the monthly + weekly + 7 daily's) each week. 

But again: if a month worth of backups (1 monthly, 4 weekly and uhm...
a lot of daily's) fit in 512 MB there is no problem at all.

A different method a keeping your backups below 512 M would be to 
add different host-statements in hdup.conf. Where each host statement
will backup different directories on your server/desktop. Ala:

[localhost1]
dir = /home

[localhost2]
dir = /var

Now you will get a set of backups, one for localhost1 and the other for
localhost2. Maybe then both backups will be smaller than 512 M. You can
write them seperatly to CD. You will then also need 2 flash pens....

Hopes this sheds some light,
