Hello Daniel, > Do you have a BBU on the raid controler ?
ADAPTEC 3805 RAID SAS/SATA 8−Kanal > Hardware RAID without BBU (and of course, without write-back cache > enabled) is usually *very* slow, much slower than simple disk system, or > software RAID. When you look at my other postings, the output of vmstat said that there many blocks received from a block device and minimal blocks sent to a block device. IMHO: BackupPC_nightly mainly reads from disk!?
