1.- Navigate to “Performance -> Operations Displays -> Interface Trends” in Dx NetOps Portal and take a screenshot for the last 7 days to verify later on whether the restore has been performed successfully:
Note there is data the 6th of September
2.- Stop the DCs services:
[[email protected] ~]# service dcmd stop
Redirecting to /bin/systemctl stop dcmd.service
[[email protected] ~]# service dcmd stop
Redirecting to /bin/systemctl stop dcmd.service
3.- Stop the DA services:
[[email protected] ~]# service dadaemon stop
Redirecting to /bin/systemctl stop dadaemon.service
4.- Log in to the DR server as the database administrator user (not as the root user) and run below command:
[[email protected] ~]# su dradmin
[[email protected] root]$
[[email protected] ~]# /opt/vertica/bin/adminTools
5.- Stop the Database (option 4 in the Menu):
6.- Exit from AdminTools:
7.- Check the available DR backups:
[[email protected] roo]$ /opt/vertica/bin/vbr.py --task listbackup --config-file /opt/vertica/config/backup_restore_full_local_TEST2.ini

/opt/vertica/bin/vbr.py --task restore --config-file <configuration_directory_path_filename> --archive <archive_name>
[[email protected] root]$ /opt/vertica/bin/vbr.py --task restore --config-file /opt/vertica/config/backup_restore_full_local_TEST2.ini --archive 20210904_060004
