It is BAD!
OK at least my tape drive is on its own card.
But, when we purchased the backup server I agreed
to follow my boss' solution (it's always him you known ;-p) to buy that
cheaper server with maximum 1,5TB RAID5 (6*300GB) instead of that nice
DAS with up to 3,9TB RAID5. So, to save space I created one big volume
containing both the OS and the data.
I guess that's the reason why I have so poor performances
with "dd if=/dev/sda2 ... bs=2048k" (where /dev/sda2 is the OS).
So, I think I will have to go into a complete hardware
configuration change... BTW, in order to finally have a good configuration,
I have started another thread about holding disk. But it seems the list
cannot keep the pace with me sending so much requests :-). The question
was simple (the answer maybe not but...):
In a configuration where amanda only backup local
(SCSI) drives, are there any benefits from using a holding disk?
Best regards,
