I had overlook this lines in BackupPC log:

2010-06-11 04:04:13 1s_trade_at_phoenix: Out of memory during "large" request 
for 16781312 bytes, total sbrk() is 529952768 bytes at 
/usr/local/BackupPC/lib/BackupPC/FileZIO.pm line 203.
2010-06-11 04:04:19 Backup failed on 1s_trade_at_phoenix (Child exited 
prematurely)

It seems that when BackupPC tries to _decompress_ 342 MB file from pool it 
consumes all available RAM and swap.
(I had 1G RAM + 1G swap). I had resolve the problem by adding extra 512 MB of 
RAM.

But the directory that I am backing up is only about 1000 Files and 2.5 GB and 
the biggest file is 342 MB. Is BackupPC really needs so much memory? Or it is 
memory leaks?
