I ran bacula and it backed up this ENTIRE client in like 7 minutes. After 40
minutes, backuppc has only backed up a measly 300MB... of a total of 1.5GB. I
am not even sure how much aready was in-use on the partition after creating the
new partition.

How can I decrease load? Can I disable deduplication or compression? The load
is very high. This back-up server (virtual machine) has a powerful processor,
although only 1GB memory (that is not fully used). Even running this simple 1
job is very very slow. See http://images.codepad.eu/v-ISmSn6.png for high cpu
usage.
Last time this back-up ran succesfully for the entire server (1.7GB) it took
more than 12 hours (after which I manually canceled the back-up). This back-up
job ran in 7 minutes(!) on Bacula. I however would prefer to use BackupPC in
the future and I hope people can help me getting decent performance.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
