Back up a Tenable Security Center in Kubernetes deployment

Log in to the Kubernetes runtime container with the following command:
Copy
```
kubectl exec -it tenable-security-center-0 -n tenable -- /bin/sh
```
Stop Tenable Security Center and all running processes:
1. Stop Tenable Security Center with the following command:
  Copy
```
/scbase/SC.sh stop
```
2. In the CLI in Tenable Security Center, run the following command to view all running processes:
  Copy
```
ps -fu tns
```
3. If any processes are listed, run the following commands to stop them:
  Copy
```
killall -u tns
```
  Copy
```
killall httpd
```
  Note: These commands stop all jobs (including scans) running on Tenable Security Center.
4. If necessary, repeat step c to confirm all processes are stopped.
Create a backup .tar file using the following command:
Copy
```
cd /opt
tar -Ppzcf /opt/sc_backup.tar.gz /opt/sc
```
Note: The.tar file switches are case-sensitive.

Tenable Security Center creates the sc_backup.tar.gz backup file in the /opt/sc directory.
Copy the backup file with the following command, where /backup/directory is the local path for the backup file:
Copy
```
kubectl exec -n tenable -c sc-runtime-container tenable-security-center-0 -- tar cf - /opt/sc_backup.tar.gz | tar xf - -C /backup/directory
```
Note: Ensure your local directory has enough space for the backup file.

Tenable Security Center is backed up to your local directory.
Remove the backup file from the opt directory with the following command:
Copy
```
rm /opt/sc_backup.tar.gz
```
Restart Tenable Security Center with the following command:
Copy
```
/scbase/SC.sh restart
```
Tenable Security Center is ready to use again.
