All configuration changes after previous backup will be lost. Do you want to continue (yes/no) [n]? y Configuration is restored successfully. CAUTION: Reinitializing the dictionary is only intended to be an operation that is performed rarely, and when performed, only under special circumstances. Because the dictionary acts as an index that maps each chunk of data to a specific location, it is referenced during a data ingest to determine if the DR4000 system has seen this data before. When you reinitialize the dictionary, all entries that indicate there were previously archived data locations are removed. As a result, during new data ingests the DR4000 will not be able to detect any duplicates based on the existing archived data. To reinitialize the dictionary on a DR4000 system, enter the following command string at the system prompt: administrator@mydr4000 > maintenance --configuration --reinit_dictionary Please enter administrator password: WARNING: ALL DICTIONARY DATA WILL BE ERASED! Do you want to continue (yes/no)? Type yes to continue or no to return to the system prompt. stop Filesystem... Done. Initializing Dictionary... Done. Restart Filesystem... Done. --hardware [--reinit_nvram, --network_reconfigure] Non-volatile RAM (NVRAM) is the type of memory that retains its contents even when power to it is turned off.
