I have a similar situation here and I tested flashbackup for Linux last in 2010. I don't mean to dissuade you, but in my test a volume that was running 30MB/sec with the standard client actually ran 28MB/sec with flashbackup. If you get any better results I would love to hear about it. I tested on 6.5.6.
The "Advanced Client" you need is in the "UnixOptions" package. This is a separate package you have to download from Symantec that has many of the advanced features for Linux, including flashbackup. As far as I am aware, this is just 6.5 / there is no patch for it. You install it after the linux client. The real secret of Linux flashbackup, is that the snapshot capability comes from the Veritax Filesystem (VxFS) not NetBackup. So you will have to create a VxFS volume and configure snapshots properly to get this to work. To do this you will need to get a copy of Symantec's Storage Foundation for Linux. (I got a trial copy from my Symantec rep.) Unfortunately, my notes are sparse. But you are welcome to them (below.) You will see the last note on 8/21 was the 28MB/sec. At this point the group with the millions of tiny files decided to purchase a NetApp and use the SnapMirror to Tape capability for backups. (Works very well.) I think I could have had better than 28MB/sec, but it requires an indepth knowledge of VxFS. -Jonathan 5/26 - Created VxVM volume and VxFS file system.

Morning all I posted about a problematic Linux system with TB's of Data. Today I have been looking at Flashbackup. I have this working on a Windows Server, but would like to look at getting this working on Linux. However... I dont have Linux experience! :-( Is there anyone that can offer some advice on getting Flashbackup working on Linux? Reading in the guide, it needs the "advance client" installed ... but where is it :-( ? I have no clue! This might help get around one of the volumes, which is a file level volume, with tons of small files. Apprecaite any feedback Simon
