I need to improve performance of a Job which backups 1500000 files (mail and File Server). I was compressing the files on disk in some tgz files first (tar and gzip) ,then backuping then on tape with Bacula, i was getting about:
Job write elapsed time = 00:32:16, Transfer rate = 44.93 M Bytes/second Because disks space constraints i have to delete the compressed files on disk and backup direct to tape, then i am getting about: Job write elapsed time = 03:56:37, Transfer rate = 11.71 M Bytes/second I think i am getting worst performance because of ramdon disk access speed, is that true? The Tape (LTO4) and Bacula Storage Daemon and Director are on different server than the file and mail server i am backuping up. Could someone has some suggestions about improving speed from Bacula or from filesystem tuning? Does Bacula software compression might help on this? I Have a HP E200 SAS Disk Controller with 512MB (with Battery Write Cache) in a Raid 5 LVM (File and Mail Server).
