NetBackup 6.5.5 How to increase speed of backup

[Maxim1984]

Dear All,

So we have 10 folders and in each folder there are about 40000 files. The problem is a reducing speed of back up. In this way how we can improve performance in our back up procedure. Our speed is more than 1 day for back up. Network speed - 1 gigabit. Drives - LTO3.

Thank you for your answers.

Do you mean Backup Exec 2010 perhaps? If you are looking for BE info, the forum can be found here: https://www-secure.symantec.com/connect/backup-and-archiving/forums/backup-exec

The latest NetBackup version is 7.1...

Sorry, NetBackup 6.5.5. My fault.

You could use flashbackup-windows to back it up.

If you have an Enterprise Client License

Please, could you give me some links about "flashbackup-windows"?

In theory you can do it with ms-win-nt, however that will put the drive in unavailable mode during backup... also the mapping portion will get skipped.

It's not good in my case because we have 1,5TB volume so we need to backup whole volume.

Time to use DeDup :)

You can do incrementals :)

Full backup takes 3 days in my case. So we need to invent  the method how to reduce the time of full backup. Backed up data size is 600 GB in 1,5 TB volume. Client windows 2003, server -win 2008. While using VSS providers we have "snapshot error encountered" and if we use volume shadow size 20 GB too.

FlashBackup will dramatically increase the speed (unless you're storage can't perform well). Unfortunately you'll have to backup the whole 1.5TB with a Full.

If you had Windows 2008 on the client you could shrink the volume :(

synthetic backups might also help....

Thank you! We will try
