Issue



This article describes how to address disk space issues on the computer where Symantec Endpoint Protection Manager (SEPM) is installed, including:

  • How to ensure that the content downloads on the Symantec Endpoint Protection Manager server are limited by days
  • How to control database growth
  • How to control the amount of disk space Symantec uses on the Symantec Endpoint Protection Manager server
  • How to best configure disk space management for security content downloads and database for the Symantec Endpoint Protection Manager
  • How to reduce the amount of disk space used by the Symantec Endpoint Protection Manager for content revisions and the database

In versions earlier than 12.1.5, these issues were critically important because of the need to store full content revisions. In version 12.1.5, only the latest full content is stored, plus the specified number of content deltas. When any specified version of the content is needed, it is constructed from the full version plus the deltas. As a result, content storage is more efficient. Larger numbers of revisions can be stored in less space. This article explains the issues for both version 12.1.5 and earlier versions.

 


Error



You may not see actual error codes, but the Symantec Endpoint Protection Manager can consume a large amount of disk space for content revisions on the filesystem and in the database.


Solution



By default, the Symantec Endpoint Protection Manager downloads and keeps a particular number of virus definition revisions in its repositories based on the type of install performed:

Default Content Revisions Stored on the Server
Installation type Default number of revisions (version 12.1.5)  Default number of revisions (earlier versions)
SEP SBE 12 (3 days' worth)  3 (1 day's worth) 
EE Simple (< 100 clients) 12 (3 days' worth)  3 (1 day's worth) 
100 - 500 clients 21 (7 days' worth)   3 (1 day's worth)
500 - 1000 clients 42 (14 days' worth)  10 (3 days' worth)
> 1000 clients 90 (30 days' worth)  30 (10 days' worth)

These numbers can be lowered to help reduce the amount of disk space that is used by content revisions. However, with versions earlier than 12.1.5, the Symantec Endpoint Protection Manager must have previous content revisions stored in order to create a "delta" file, or differential file, capable of updating a client from its version of that content type to the most recent type. Therefore, if you reduce the number of content revisions that the SEPM stores, the clients may download larger deltas or full package downloads depending on their current content revision date. For detailed information on how to determine how many content revisions to keep see: Best Practices for configuring the number of content revisions to keep in Symantec Endpoint Protection Manager

With version 12.1.5, you may find it unnecessary to lower these numbers, and in certain cases you may find it helpful to increase them without having to sacrifice large amounts of disk space.
