Slow file data backups

[Jan_Rustico]

We are using Symantec NetbackUp 7.6.0.1 in Windows Server 2008 R2 and I have a problem regarding backing up our file data. Our File data is composed of *.pst's, office productivity documents like .xls, .doc, .pps/,ppt, autocad files and images. the current drive used by these files are around 3TB. We do not have snapshot backup license. Network connection between the file server and the master server is excellent as per SAS report. Our file server is running windows server 2012 R2 standard  (hyper-V). it takes more than 18-28 hours to backup to disk and more than 6 hours to duplicate to tape. This is the only exception we have in the backup system (that it takes time to backup and duplicate unlike the others). i soaght the help of Symantec Netbackup technical support team - india and still the issue persist. its more than 3 weeks now since I worked with them. Please help. thanks.

Update client software to 7.6.0.4 - there are some improvement in the accelerator logic

Besides that - you need to look at the infrastructure. Software can't make hardware run faster.

There are some great tips in the Netbackup Backup Planing and Performance tuning guide in section 2

Besides that - backup of small files never reach big transfer speed - but there is of cause a lower limit.
