2.1 Restoring Backup Files Under www
① Save the backup file used for restoration to the server's "/" (root) directory.

# cd /srv/www/backup/www_bak # cp www_back_[time-stamp].tar.gz / |
② Extract the file
|
1 2 |
# cd / # tar zxvf www_back_[time-stamp].tar.gz |
2.2 Restore MariaDB data
① Save the database backup file to any directory
(in this example, the "/srv/www/backup/db_bak" directory) and extract the data.
|
1 2 |
# cd /srv/www/backup/db_bak # gzip -d mariadb_backup_[time-stamp].dump.gz |
② Restore the MariaDB database
