Any clues in the dsmerror.log? >>> [EMAIL PROTECTED] 05/20/05 11:41 AM >>> Hello *SM'ers,
Has anyone observed the following; We are experienceing performance problems with LanFree backups. The issue goes away with a retsart of the storage agent, but at some point in the future comes back, requiring another restart of the stoarge agent etc.. Now, when the backups are going OK, the following steps are observed, take note of what happens to the ByteCount (IE: the small cumulative indicator in the square brackets at the command line, '[12.3 G]') ; Backup started First directory entry sent Backup pauses, while byte count increments Backup generates 'unsuccesful' line, and then 'waiting for mount of offline media' ByteCount PAUSES When tape is mounted and wound, BYTECOUNT increases Very Fast. (+100 - 200MB / 'tick' ) Then end stats show simlar to; Total number of objects inspected: 3 Total number of objects backed up: 3 Total number of objects updated: 0 Total number of objects rebound: 0 Total number of objects deleted: 0 Total number of objects expired: 0 Total number of objects failed: 0 Total number of bytes transferred: 4.70 GB LanFree data bytes: 4.70 GB Data transfer time: 153.13 sec Network data transfer rate: 32,229.74 KB/sec Aggregate data transfer rate: 28,567.48 KB/sec Objects compressed by: 0% Elapsed processing time: 00:02:52 ..NOTE, ALL data has gone LanFree Now, when the backups are performing slowly, the following occurrs; Backup started First directory entry sent Backup pauses, while byte count increments Backup generates 'unsuccesful' line, and then 'waiting for mount of offline media' ByteCount CONTINUES TO INCREMENT SLOWLY (+15-20 MB / 'tick') When tape is mounted and wound, BYTECOUNT INCREMENTS SLOWLY (+15 - 20MB / 'tick') At the end of backup, we see this; Total number of objects inspected: 6 Total number of objects backed up: 2 Total number of objects updated: 0 Total number of objects rebound: 0 Total number of objects deleted: 0 Total number of objects expired: 0 Total number of objects failed: 0 Total number of bytes transferred: 4.18 GB LanFree data bytes: 2.37 GB Data transfer time: 42.01 sec Network data transfer rate: 104,402.77 KB/sec Aggregate data transfer rate: 15,331.31 KB/sec Objects compressed by: 0% Elapsed processing time: 00:04:46 Does this indicate, that in this instance some data went LanFree while some went LAN?? .. and what significance is the fact that the BYTECOUNT increases slowly while waiting for a mediamount, but it doesn't when the backup performs well?
