More BackupPC sizing considerations

After the ALIX had failed, I moved my BackupPC instance to a leftover Dell workstation with 1.7 GHZ Pentium 4 and 768 GB MB of RAM.

While this is somewhat usable, the machine is badly overloaded. When multiple backup tasks are running, all RAM plus 1 GB of swap space are fully used. And the USB 2.0 disk used for storage causes the system to be waiting for I/O 70-90% of the time. On the other hand, I should probably stop the manual scheduling of backup jobs and let BackupPC do it on its own.

Nevertheless, it can be said that retrieving, compressing and indexing files surely appears to be a lot more work than just serving them. 🙂
