Filesystem Backup and Restore

8 min

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

Stopping Database Replication

Execute the following commands only on the node where the backup/restore operation is performed.

Check SymmetricDS replication status. [root@kronpam~]# /u01/sym/symmetric-server-3.10.5/bin/sym_service status
Stop SymmetricDS replication. [root@kronpam~]# /u01/sym/symmetric-server-3.10.5/bin/sym_service stop

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

Prerequisite: Check once again that you have enough disk space for backup.

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

During the restoration, backup files will overwrite the existing files.

Execute the commands described below with the root user. [root@kronpam~]# cd / [root@kronpam~]# tar -xvpzf /backup.tar.gz -C /
Once extraction is complete, recreate directories that were not included in the original archive. [root@singleconnect~]# mkdir /proc /lost+found /media /mnt

Execute the commands in the 3rd and 4th steps only on the node where the backup operation is performed.

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
