**Prerequisite**
This procedure requires stopping applications. Complete all active operations on the instance.
:::

# Stopping Database Replication

:::hint{type="info"}
Execute the following commands only on the node where the backup/restore operation is performed.
:::

1. Check SymmetricDS replication status.
   **\[root\@kronpam\~]# **/u01/sym/symmetric-server-3.10.5/bin/sym\_service status

2. Stop SymmetricDS replication.
   **\[root\@kronpam\~]#** /u01/sym/symmetric-server-3.10.5/bin/sym\_service stop 

# Stopping Services

1. Stop Kron PAM module services.
   **\[root\@kronpam\~]# **systemctl stop kron\_tacacs                                             **\[root\@kronpam\~]# **systemctl stop radiusd                                                   **\[root\@kronpam\~]# **systemctl stop guacd                                                              **\[root\@kronpam\~]# **systemctl stop netright-tomcat                                        **\[root\@kronpam\~]# **systemctl stop mobile-tomcat                                         **\[root\@kronpam\~]# **systemctl stop nssoapp                                                     **\[root\@kronpam\~]# **systemctl stop sftp\_prox                                                   **\[root\@kronpam\~]# **systemctl stop sqlprox                                                        **\[root\@kronpam\~]# **systemctl stop http\_prox                                                   **\[root\@kronpam\~]# **systemctl stop ppas-9.5

# Backing up Filesystem

:::hint{type="info"}
**Prerequisite:** Check once again that you have enough disk space for backup. 
:::

1. Execute the commands described below with the root user.
   **\[root\@kronpam\~]# **cd /                                                                                              **\[root\@kronpam\~]# **TIMESTAMP=\`date +%Y%m%d\_%H%M\`                                  **\[root\@kronpam\~]# **tar -cvpzf backup\_$TIMESTAMP.tar.gz --exclude=/backup\_$TIMESTAMP.tar.gz --exclude=/proc --exclude=/lost+found --exclude=/media --exclude=/mnt

# Restoring Filesystem

:::hint{type="danger"}
During the restoration, backup files will overwrite the existing files.
:::

1. Execute the commands described below with the root user.
   **\[root\@kronpam\~]# **cd /                                                                                            **\[root\@kronpam\~]# **tar -xvpzf /backup.tar.gz -C /

2. Once extraction is complete, recreate directories that were not included in the original archive.
   **\[root\@singleconnect\~]# **mkdir /proc /lost+found /media /mnt

# After Backup Operations

:::hint{type="info"}
Execute the commands in the 3rd and 4th steps only on the node where the backup operation is performed.
:::

1. Start services.
   **\[root\@kronpam\~]#** systemctl start kron\_tacacs                                                      **\[root\@kronpam\~]#** systemctl start radiusd                                                          **\[root\@kronpam\~]# **systemctl start guacd                                                      **\[root\@kronpam\~]# **systemctl start netright-tomcat                                                   **\[root\@kronpam\~]# **systemctl start mobile-tomcat                                          **\[root\@kronpam\~]# **systemctl start nssoapp                                                  **\[root\@kronpam\~]# **systemctl start sftp\_prox                                                   **\[root\@kronpam\~]#** systemctl start sqlprox                                                      **\[root\@kronpam\~]#** systemctl start http\_prox                                                          **\[root\@kronpam\~]#** systemctl start ppas-9.5     
2. Start database replication. 

3. Check SymmetricDS replication status.
   **\[root\@kronpam\~]# **/u01/sym/symmetric-server-3.10.5/bin/sym\_service status.

4. Stop SymmetricDS replication.
   **\[root\@kronpam\~]# **/u01/sym/symmetric-server-3.10.5/bin/sym\_service status
