Hi,
NetBackup Catalog Size on disk in my environment is around 100 GB and when I do a catalog backup, it backs up around 150 GB.
Is it because of a fragmented disk in Windows?
Is it advisory to do Defragmentation of the Disk in which NetBackup catalog reside?
NBU version : 6.5.5
OS : Windows 2003 SP2.
Solved! Go to Solution.

I agree with the above excellent posts - the main data is in the images directory - it also backs up the EMM and BMR etc. databases but generally there would not be very large
Check in Windows Explorer to make sure that the file system your catalog is on, or at least the images or sub folders, as not using file system compression - not a good idea for the catalog area
Hope this helps

No.
How do you know it backs up '150GB ' ? Where do you get this value.
What is the exact size of the Catalog, how do you get this value ?
We can see the amount backed up in the bptm log, I would incrase the VERBOSE level to 5 and then send this in, after running a new Catalog backup.
Thanks,
Martin

Check your /usr/openv/netbackup/db/images folder size is mainly where most of the catalog data is, there are some other folders but this is the biggest one.

NetBackup is installed in the E drive of the Master Server.
I checked the properties of the E drive; the Used Space comes around 70-80 GB out of its allocated 150GB, but when the Catalog Backup runs I could see from the Detailed Status the KiloBytes written comes around 120 GB.
Shouldn't it be just 70-80 GB?
Thanks all for your reply.

So if you highlight all of the folders on the E drive, right click and select "Properties" (this will take a while!)
What do you see?
Is the "size" and "size on disk" the same?
01-24-2012 07:30 AM
Images is the main dir yes, but the others can be quite larger, or at least larger than you might think.
Hence why I asked how the size of the catalog was calculated, and not, how big is images on its own.

Of course how do you know NetBackup is not correct and the operating system should be 'just 120GB'
bptm will show what NBU is calculating ...

I selected the Program Files directory in E drive(thats where the NetBackup SW is installed, also the Images directory) and did a properties. Below is the result.
Size : 125GB
Size of Disk : 64.3 GB

So there you go!
As i said previously you disk is using compression and the catalog is 120GB
If you have the free space i would strongly suggest that you uncompress the folders involved (whilst NetBackup is quiet)
But i think your question is answered - Glad to have helped
#edit# I see your disk is 150GB in size so you are running very close - EMM will go down when you get low on disk space so expand it and then uncompress it if this is possible - or more it to another drive with more space

Is the File system compression you're talking about is enabled at Disk Management -> Choose Partition
--> Properties --> Select the Check box"Compress Drive to save disk space"
If so, I think its not enabled. Please find the screenshot.

Take a look at your drive in Windows Explorer - do any of the folders show up as blue?
If you select in the columns to show the Attributes this should also show up if anything is compressed
Plus ... if you right click a blue folder, select Properties and then on the General tab select the Advanced button there is an option in there to compress the folder - unckecking that should uncompress the files - but make sure you have enough disk space to leave at least 10% free (preferably a lot more!)
You may be able to do it at a top level "blue" folder or may have to uncompress folder by folder
01-24-2012 09:14 AM
I understand what you mean by those Blue Folders, but I do not see any of them in the E drive(where NetBackup resides).
I only see them at the System Drive(C Drive) and those are the ones inside the C:\WINDOWS folder, with Windows Update uninstallable folders, I believe that they're normal.
01-24-2012 09:21 AM
Some of the folder in your catalog drive must be compressed and their attributes should show it
On the properties page you showed earlier, if you click the Advanced button on there is the compress files and folders option checked?
If so you can uncked it and ensure you select apply to all folders and sub folders and it will uncompress them
This will take a long time and NetBackup should be quiet whilst it does its stuff
I cannot stress enough you must ensure you have enough disk space to actually uncompress it all
Here is what the attribute looks like:
01-24-2012 09:37 AM
I checked the attribute whether it is C, and it is not. I browsed into some of the directories inside Program Files as well as the NetBackup, images, NetBackup DB folders, but none of them were.
Also the Advanced Tab doesn't show that the compression option is enabled. I have logged a case with Symantec now, I thought this was easy.

OK - just had another thought on this one ....
As you are struggling to find and folders showing compression it may just be the catalog files themselves that have been compressed.
As you are on Windows with an NTFS partition this could have been as a result of someone choosing Catalog Compression in the Master Servers Host Properties - Global Attributes section.
This tech note describes what this does:
http://www.symantec.com/docs/HOWTO34441
So if you want to undo this (uncmpress it) you need to follow the correct proceedure - but again I must stress that it is vital you have enough disk space to be able to do it - which I don't believe you do at the moment.
Please see this tech note that describes the correct proceedure to uncompress it if you decide you want to:
http://www.symantec.com/docs/HOWTO34467
Having said that your question was "NetBackup Catalog Size on disk in my environment is around 100 GB and when I do a catalog backup, it backs up around 150 GB" and I believe that the question has been answered based on the figures you have provided (Size = 125GB, Size on Disk =64.3GB) which clearly shows compression is being used - and I suspect it is NetBackup doing this compression.
Hope this helps and puts you in a position to deal with the issue
