[BackupPC-users] Increasing full backup speed?

[Jason B <co...@bd...>]

Hi all,

First off, just wanted to say thank you to everyone who helped me with my 
Aborted by signal ALRM problem when backing up huge dirs, especially Jason and 
Holger. Using the Exclude dirs parameter worked beautifully, and I just re-ran 
the full backup every day for about a week, gradually excluding less and less 
and it finally completed and has been working well since.

The question I have is this. I'm in the process of doing this for the second 
server, which is 140GB in many thousands of files, and doing a full backup 
actually takes quite a while just to generate all the hardlinks before it even 
gets to transferring data. What constrains the speed at which these hardlinks 
are created - the backuppc server's CPU, the client's CPU (for rsync 
checksums), the disk speed (running ext3 / raid5 on 5 drives), or what else 
could it be?

Thanks very much.
