Hello,

the commentary from Rob Steele bellow the article in 
http://jeremy.zawodny.com/blog/archives/010037.html seems quite relevant to me. 
I have tried rsync and cp in the past but had the already mentioned memory and 
time issues so I'm planning to give his suggestion (BackupPC_tarPCCopy to make 
the first copy) a try.

Cheers,
