After a reboot I got the following values:

Before launching any BackupPC process:

              total         used         free       shared      buffers
  Mem:        30412        21884         8528            0         9480
 Swap:       500508            0       500508
Total:       530920        21884       509036

After launching '/etc/init.d/backuppc start':

              total         used         free       shared      buffers
  Mem:        30412        27392         3020            0         7540
 Swap:       500508            0       500508
Total:       530920        27392       503528

After launching '/usr/local/BackupPC/bin/BackupPC_serverMesg status info':

              total         used         free       shared      buffers
  Mem:        30412        29228         1184            0         4932
 Swap:       500508            0       500508
Total:       530920        29228       501692

Seems that swap space isn't even needed. I am astonished, too, because free 
shows 24, 22, and 16% memory usage by the three BackupPC processes, whereas 
the above figures seem to show that the BackupPC processes just need 
additional 7,5 MB which is less than 25% of the device's 32MB RAM.

Strange, isn't it?
