catstore folder under db/images/<client>/<10 digit number>/ consumig large space

Created: 26 May 2009 • Updated: 21 May 2010 | 3 comments

We have one Solaris 10 master server with Netbackup 6.5.2 with mixture of solaris, AIX, windows media servers.

Issue:

The catstore folder under /usr/openv/netbackup/db/images/<client>/<10 digit number>/ is consuming large space.  Specifically the folder under the NDMP client. Its size has grown 12 GB in one week and its growing more.

Can any one let me know what is the purpose of catstore folder and whether can we remove any files from it to reduce the growing size.

My understanding of this directory is that, it is a collector directory that contains temp files that are created while backups are running and are cleared out after a backup completes

Please clarify and suggest any ways to reduce the size of images folder.

Hi,

the 10 digit number contains the header and files files for your backups. If the 'files' files with the .f extension become larger than 4 Mb,they are reloated to catstore folder. These are not temp files.  Basically when you use the BAR gui or bplist command, al the files that show up in the restore window come from these .f files

You shoudl never remove any files from inside the catstore directory

if the size is the issue, you can either 1) compress the catalog 2) use ALTPATH to change the location where the images info for this client would be stored.

I already have the different filesystem created and have a symbolic link to it.

But is that only the way to go for dealing with netbackup DB images folder size growing.

Could let me know how to use or set the option 1.  If i use that will there any issues while restore.

In the console, go to Host properties > Master server > global attributes > Select Compress catalog interval after x days.

with catalog compression, there is one issue that I know :
