OK. If I understand correctly, rsync compares against the last full backup
and since there is only one backup, you're saying that the incrementals will
get larger and larger?

However, the machine I am backing up is different. Basically the full backup
I have done wil NEVER change. The user only makes ADDITIONS to the full
backup and does not edit old files or anything; in fact, the data on his
machine is essentially static data. It is itself a kind of mini-storage
server. What you have highlighted would be relevant if I was to back up his
volatile laptop, which is like any other client.

So my reasons for doing incrementals forever are correct, the question is
HOW can I setup such a routine?

In appreciation and anticipation of your response,

Khaled

Be sure you understand how rsync incrementals actually work before you
do that.  The comparison is always done against the most recent full
backup, so as that copy ages you will repeated pull a growing set of
all files that have changed since then for every incremental run.

An rsync full backup, on the other hand, takes more real and CPU time
at each end because it compares all files regardless of the timestamps,
but it takes very little more bandwidth - and will likely result in
less bandwidth being used for the next run.
