Deduplication when using SQL Server backup compression
A quick question about using NetBackup with compressed SQL Server backups. Our backups infrastructure consists of NetBackup v7.6 and NetBackup 5230 appliances. Our SQL server estate is a mixture of SQL Server versions 2005-2012 on Windows 2003-2012. We've noticed that the deduplication ratio (as reported by backup jobs in Netbackup Activity Monitor) for compressed SQL backups is 0% (we experimented with the NetBackup SQL Agent and alsostandard flat file backups). Now we weren't expecting to get much deduplication out of a compressed SQL Server backup - but it was a suprise to get nothing at all. Previous tests performed on other deduplication platforms(Exagrid and Windows native 2012 deduplication) showed that a noticeable (albeit muchlower rate compared with uncompressed backups)deduplication level of about4:1 was possible withcompressed SQL Server backups. So my question is - is this a configuration issue on our NetBackup infrastructure - or is there a technical\designreason why thededuplication of compressed SQL Server backups is not available inNetBackup?

Hi, the Puredisk SPA Authorization Service is not starting on N5020, so it's impossible to use N5020. Last Night at 4.00AM Netbackup has lost contact with N5020, the error was 213. trying to update Storage Server credential now returns this error: RDSM has encountered an STS error: getStorageServerInfo on N5020, we tried to stop Puredisk services (all of them were listed as running), with no success and with one specific error: Starting Puredisk SPA Authorization Service: java /opt/pdspa/tomcat/bin failed i can also see a lot of "webservice call" errors in N5020 logs i also can see a lot of execfail*** under /tmp, like this one: cat execfailDF2SPu Unable to run operation, please see troubleshooting logs for more error information\nExitcode was 1 array ( )Command was /opt/pdctrl/bin/pdmanage --agent 496000000 --server nba-5020.client.it --wait --command "/opt/pdag/bin/php /opt/pdmbe/cli/MBEDUSummary.php" 2>/Storage/tmp/STDEPDMQh98zbError output is Sun Nov 4 2012 12:30:01.876879 ERROR (47814416437568): A remote error occurred: Authentication failed.
