Hi, Problem: Migrate/Copy jobs from disk pool (DiskBackup) to tape (DiskCopy) only get overall speed of 10-20MB/s.
full backup job size varies from 10-50GB. Pool setup is simple, just one pool for full an incremental backups to disk (automatic recycle works good) Pool { Name = DiskBackup Pool Type = Backup Recycle = yes RecyclePool = DiskBackup AutoPrune = yes Volume Retention = 15 days Volume Use Duration = 6 days Maximum Volume Bytes = 4G Label Format = Backup- Next Pool = DiskCopy } DiskCopy pool goes to LTO4 tape device. DiskBackup goes to SATA external raid (6T ext3). concurrency for DiskBackup jobs is 15, jobs are spread over DiskBackup Valumes (maybe thats the main problem) i can read write/continuous on both devices at about 70MB/s (SATA is not fast) i tried spooling to local SAS raid, but overall speed is lower than direct writing to tape. despooling from SAS raid to Tape runs at Tape maximum spped. I need some Performance tuning tips, maybe: Limit jobs per Volume in DiskBackup pools? Split DiskBackup into DiskFull and DiskIncr pools? Pool { Name = DiskFull Pool Type = Backup Recycle = yes RecyclePool = DiskFull AutoPrune = yes Volume Retention = 15 days Volume Use Duration = 6 days Maximum Volume Jobs = 1 Maximum Volume Bytes = 10G Label Format = Full- Next Pool = DiskCopy } Thx Ulrich -- Ulrich Leodolter <[EMAIL PROTECTED]> ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
