Re: [BackupPC-users] high load and stuck processes

[Anand G. <ana...@gm...>]

Hi Les,

Thanks for the reply.

As i mentioned in my mail, the server has 8gb ram. It has a adaptec 3405 8
port raid card with sata drives ( 8 x 750gb - raid 5).

Right now the maxbackups is set to 8 (i did this thinking the server was
powerful enough to handle that many number of clients at one shot). Another
reason being, there are like 100+ clients in the network, so if the number
of too low, then all clients might not get backed up. Will try the setting
and see if anything changes.

Thanks and Regards,

Anand Gupta
