There are 89 hosts that have been backed up, for a total of:
* 580 full backups of total size 5596.07GB (prior to pooling and
compression),
* 529 incr backups of total size 943.57GB (prior to pooling and
compression).
Except 2 or 3 these are all Linux Servers. We use a Dell PE840 with 8GB
RAM and a RAID-10 (md) of 4 1TB SATA Disks. Right now we are running
into performance troubles (backuptimes getting > 1 day)
Most of the times, the performace bottleneck is the disk-speed (we ve
got large amount of small files). Raid-10 did its thing but now we
reached the end again, see the i/o wait:
