ESM Full Backup - Estimated Space Needed

Hello All,

I am someone relatively new to the ESM, and I am currently trying to calculate what amount of space I need to perform a full backup of the system. Technical Article ID: KB85742 stated to go to the following directory and sum the total values:

  •   a = size of  /usr/local/ess/data/
  •   b = size of  /data_hd/usr/local/ess/data/
  •   c = size of /index_hd/usr/local/ess/data/
  •   d = size of /Das1_hd/usr/local/data/  (this will apply only if you have a Direct Attached Storage (DAS) device connected to your ESM)
  •   e = add 10% to (a+b+c+d)
Can someone guide me through those steps, or is there an easier way to do this via the SIEM's UI?
Thanks in advance!

Re: ESM Full Backup - Estimated Space Needed


Here's the easiest way to do it.

Go to each directory as stated and then execute 'du -sh' to get the size 


McAfee-ENMELM~ # cd /usr/local/ess/data/
McAfee-ENMELM /usr/local/ess/data # du -sh
1.6G .

Do the same with other directories.

i hope this information can help you


you can use the du command


McAfee-ETM-5600 ~ # du /usr/local/ess/data/

15381700 /usr/local/ess/data/old_sa
18480516 /usr/local/ess/data/

McAfee-ETM-5600 ~ # du /usr/local/ess/data/
15381700 /usr/local/ess/data/old_sa
18480516 /usr/local/ess/data/





if you want the size un GB you must use the next sentence for every directory


du -csh --block-size=1G /usr/local/ess/data/

 In my case the the result are the following

18 /usr/local/ess/data/
18 total
