Backing up KUMA
KUMA allows you to back up the KUMA Core database and certificates. Backups may be created using the executable file /opt/kaspersky/kuma/kuma.
Data may only be restored from a backup if it is restored to the KUMA of the same version as the backup one.
To perform a backup:
Log in to the OS of the server where the KUMA Core is installed as the root user. Execute the following command:/opt/kaspersky/kuma/kuma tools backup --dst <path to the backup folder> --certificates
The flag --certificates is optional and is used to back up certificates.
The backup copy has been created.
To restore data from a backup:
Log in to the OS of the server where the KUMA Core is installed as the root user. On the KUMA Core server, run the following command:sudo systemctl stop kuma-core
Execute the following command:/opt/kaspersky/kuma/kuma tools restore --src <path to the backup folder> --certificates
The --certificates flag is optional and is used to restore certificates.
Start KUMA by running the following command:sudo systemctl start kuma-core
Rebuild the services using the recovered service resource sets. Data is restored from the backup.
What to do if KUMA malfunctions after restoring data from a backup copy
If the KUMA Core fails to start after data recovery, the recovery must be performed again but this time the KUMA database in MongoDB® must be reset.
To restore KUMA data and reset the MongoDB database:
Log in to the OS of the server where the KUMA Core is installed. On the KUMA Core server, run the following command:sudo systemctl stop kuma-core
Log in to MongoDB by running the following commands:cd /opt/kaspersky/kuma/mongodb/bin/./mongo Reset the MongoDB database by running the following commands:use kumadb.dropDatabase() Log out of the MongoDB database by pressing Ctrl+C . Restore data from a backup copy by running the following command:sudo /opt/kaspersky/kuma/kuma tools restore --src <path to folder containing backup copy> --certificates
The --certificates flag is optional and is used to restore certificates.
Start KUMA by running the following command:sudo systemctl start kuma-core
Rebuild the services using the recovered service resource sets. Data is restored from the backup.
Collectors are not required to be backed up, except for SQL-connected collectors. When restoring such collectors, you should revert to the original initial value of the ID.
