So thanks to [NAME], here is the answer. The deletion of the TTF files can be turned off in the adapter configuration:  In the following file (on the analytics VM): /usr/lib/vmware-vcops/user/plugins/inbound/emc_symmetrix_adapter3/conf/emc_symmetrix.properties  Change this option to 'TRUE': BACKUP_COMPRESSED_INPUT_FILES_AFTER_PROCESSING=false  And restart vCops.
The Symmetrix adapter for vCOps connects to the Solutions Enabler server to collect TTF files for the performance information. After it ingests the files, it deletes them. What if you want to save them for reviewing during troubleshooting?
