arcserve-KB : How to reduce number of "LogHistory" folders in Arcserve UDP ?

Last Update: 2017-03-03 12:44:01 UTC

Product: arcserve UDP


Reduce the no of the LogHistory folder in the UDP Agent\RPS\Proxy LOG directory




By default, Arcserve UDP keeps 13 weeks log history which are located in: C:\Program Files\CA\arcserve Unified Data Protection\Engine\Logs.

While this folder is compressed it can still consume a lot of disk space, because of this you can change the default policy to have UDP rotate/purge logs more frequently

We can limit the number of log histories through the below registry tweak:

[HKEY_LOCAL_MACHINE\SOFTWARE\CA\ARCserve Unified Data Protection\Engine\AFCoreInterface] 


 Note:The AFCoreInterface key does'nt exist by default and it has to be created manually.





  • In current logic, it only moves log to history folder every 1 month. By default keeps 3 “LogHistory” folders, but this can be controlled by this registry value.
  • The minimum value of “LogHistory” is 1.
  • The change to the log history folder will not be affected immediately but only after the weekly purge of the Activity log.
  • This only affects the agent logs in the Engine/Log folder. It does not include logs generated from Java program (web services).
