Subject: RE: [Veritas-bu] VSP Clarification
The vsp file is what is used to
keep track of changes to open files while you are doing backups.
If you don’t use the vsp you
cannot backup open files. So the setting of the vsp (or now vss for 2003
and 2008 servers) is set to either fail if it cannot get the file, or give up
on the open file and continue on.
You will see this on your windows
servers – there will be a dir that has vsp in its name.
Now if the backup was running and
it failed it might leave the vsp file behind and use up your disk space.
If your virus scanner is scanning
the file when the job finishes it might not be able to remove the file and it
gets left behind.
So you need to exclude that file
with your virus scanning.

if you cannot get the vsp file to
remove because it is busy you might have to use the pid killer to get it to
release the file.

Subject: [Veritas-bu] VSP Clarification
Hey guys
I was reading the VSP overview for Netbackup 6.5 and was a
little confused on the virtual drive creation and the VSP cache file creation.
Where is the virtual drive created? And what exactly is inside the VSP cache
file. I read through the documentation but still unclear on these things so
anyone that can put this piece
of the documentation into layman's terms I would
appreciate it, thanks.
VSP overview
NetBackup uses VSP to back up open and active files on Windows
2000, Windows XP, and Windows Server 2003 (32- and 64-bit) clients. For VSP to back
up open and active files, VSP first captures a snapshot of each volume to be
backed up.
A virtual drive is created that represents a
static copy of the volume at a point-in-time. A corresponding VSP cache
file is also created. NetBackup backs up files using the virtual drive
instead of the actual drive. For each volume snapshot, a VSP cache file is
created to maintain the integrity of the snapshot. The cache
file stores the original data that reflects the changes that occurred during
the backup. The cache file is created along with the volume snapshot.
