"The Pradhan Mantri Jan Arogya Yojana - Mukhyamantri Amrutam, (PMJAY-MA) Ayushman cards will ensure top quality and affordable medical care," he said.

Referring to the spirit of 'Sarve Santu Niramaya' (May all be free of diseases), the Prime Minister said Ayushman Yojana aims for health for all.

He appreciated the enormity of the campaign of distributing 50 lakh cards to the people in the state.

"This bears testimony to the sensitivity of the Gujarat Government. We have been hearing about health insurance in many countries of the world but India is going beyond that, ensuring health assurance," he said.

"In the earlier governments, schemes for the benefit of the common man had become a mere formality. The money that was spent on these schemes was done keeping in mind a particular area and political interests. It was necessary to change this situation and we took the lead in this change. Today when planning is done, we first study the condition of common citizens and study their needs," he said.

The Prime Minister also interacted with the beneficiaries of PMJAY-MA Yojana Ayushman cards.

Interacting with Piyushbhai from Tuwar in Banaskantha, the Prime Minister enquired about his family and his recent health conditions. The Prime Minister was happy to know that the Ayushman Bharat scheme had given him a new lease on life. Modi assured him that the government will always take care of everyone like him.

The Prime Minister interacted with Shri Damor Lalabhai Somabhai from Mahisagar and inquired if his cancer treatment went through well.

UNI ASU SHK2258。很多人服务器被黑后才发现数据库没备份，几年的内容一夜归零。其实一个shell脚本加一个定时任务就能解决。    下面这个脚本同时备份MySQL数据库和网站源码，按日期命名，保留最近7天。Linux服务器直接放到/root/backup.sh，Windows可以改成PowerShell版本，或者把Linux脚本放在宝塔面板的Shell终端里执行。    

#!/bin/bash
SITE_DIR="/www/wwwroot/yoursite"
DB_NAME="yourdb"
DB_USER="root"
DB_PASS="yourpass"
BACKUP_DIR="/backup/$(date +%Y%m%d)"
 
mkdir -p $BACKUP_DIR
 
# 备份数据库
mysqldump -u$DB_USER -p$DB_PASS --single-transaction $DB_NAME | gzip > $BACKUP_DIR/db.sql.gz
 
# 备份网站文件
tar -czf $BACKUP_DIR/files.tar.gz -C $(dirname $SITE_DIR) $(basename $SITE_DIR)
 
# 删除7天前的备份
find /backup -maxdepth 1 -type d -mtime +7 -exec rm -rf {} \;

    脚本写好之后加一条crontab，每天凌晨3点执行。备份文件建议再同步一份到对象存储，比如阿里云OSS或腾讯云COS，做到异地容灾。    # crontab -e    0 3 * * * /bin/bash /root/backup.sh >> /var/log/backup.log 2>&1    数据来源：MySQL Reference Manual 8.0（mysqldump），Linux crontab官方文档
