Performance issues on SQL Server due to Netbackup
In one of our client environment, we have Netbackup 220.127.116.11 performing backups of the whole SQL Server VM using VMWare type backup (like snapshot as per our Intel tech description). When these backups are runnings, the system kinda freezes up IO activity and its impacting SQL Server.
Since I don't have any knowledge (I am a SQL guy), I would like to know there are any best practice recommendations from Symantec for performing backups on SQL Server. If these type of snapshot backups are not recommended and instead use netbackup agent to perform windows type backup ?
Any advise on Netbackup related to SQL would be really appreciated.
