You need to calculate the average space needed by LiveUpdate Administrator (LUA) in a standard configuration set.
The size necessary will depend on what products are configured in LUA 2.x for download and distribution, and whether full products or only the necessary components are selected. Estimates below are based on current SEP definitions available in May 2010. The necessary sizes will increase over time as protection is added against additional threats.
We will use a typical Symantec Endpoint Protection (SEP) 11.x configuration in the calculation.
|Additional information and illustrations on how LUA 2.x downloads, stores, and purges contents can be found in the Connect Forum article, Managing LiveUpdate Administrator 2.x Space Usage.|
LUA 2.x has a Temporary Download Folder, a Downloaded Definitions Storage Folder ("Manage Updates"), a Definitions Test Distribution Folder (optional) and a Definitions Production Distribution Folder.
1. Temporary Download Folder
Default location: \TempDownload
Updates are copied to the TempDownload folder prior to their distribution, and are then deleted. The temporary download folder should have no permanent content, apart from 1-5 KB.
This folder size grows for downloads, but is cleared each time again. Allow 2 GB (maximum possible daily download) for this folder in your total disk space calculation.
2. Downloaded Definitions Storage Folder (Manage Updates Folder)
Default location: <App_data_path>\All Users\Symantec\LiveUpdate Administrator\Downloads
This folder has average 4 GB, is purged weekly based on revisions to keep, configurable in the LUA console.
3. Definitions Test Distribution Folder (Distribution Center)
Default location: C:\Program Files\Symantec\LiveUpdate Administrator\clu-test
Same size as in 4. Definitions Production Distribution folder. If you use the folder, double the space needed in 4.
4. Definitions Production Distribution Folder (Distribution Center)
Default location: C:\Program Files\Symantec\LiveUpdate Administrator\clu-prod
Full SEP content (typical initial download) >> 2.4 GB
Temporary Download folder >> 2 GB
Downloaded Definitions folder >> 4 GB
Definitions Test Distribution >> 3 GB (optional)
Definitions Production Distribution >> 3 GB
Total >> 12GB (optional)
Total >> 9GB (minimum)
|The Connect Forum article How Big are Current Symantec Endpoint Protection Definitions? provides additional insight, plus illustrations of file sizes as of September 2012.|
In the main screen of LUA 2.x, "System Statistics" presents a count of how much free disk space is available on the server, how large the size of the LUA database is, and how much space is used by downloaded content. Administrators should monitor these figures for excessive use.
