End of Steps Manually Recovering OMM Installation Path The OMM installation directory needs to be backed up when the OMM is installed or upgraded. The OMM installation file is manually backed up rather than backed up in real time. When the OMM installation file is damaged and there is no latest entire OMM installation path backup, you can copy the original entire path backup file, and then recover the file. Finally, the NetNumen U31 system is recovered to the latest configuration. Steps 1. Stop the NetNumen U31 service programs. 2. Upload the backup path to the NetNumen U31 server, and run the following commands to decompress the files. #cd /home/backupfile #tar -zxvf ems.tar.gz -C / /home/backupfile is the storage path for the backup files. 3.
