Hm... ok... Speed estimated for LTO1 is among 12 ~ 15 MB/sec.
Just remembering, I got same "problem" doing backups without use of spool. Answers: No, my CPU is all time near of zero load..This server is only for backups, so isnt anything running in it other than bacula. No, harddisk is normal. Spool Directory is local and data (source of backup) is local too. All job is between disk and tape. My Spool size is 100Gb.
