During an archive run the dtrace log data can grow very quickly and take up a large amount of disk space. To reduce the size of the log file(s) the following filter exclusion can be added. This can signficantly reduce the size of the dtrace file(s).
1. Launch Dtrace on the Enterprise Vault server running the SharePoint archiving task.
2. At the DT> prompt enter the following:
filter exclude "AddSidToDacl"
filter exclude "AddSidsToDacl"
