Linux 纯shell备份文件

克隆项目并进入项目目录：git clone https://github.91chi.fun/https://github.com/Pricetx/backup.git;cd backup

创建所需目录：mkdir -p /root/backups/temp/

添加脚本可执行权限：chmod +x backup.sh

编辑配置文件backup.cfg,注释写的很清楚，要配置的也不多，注意：最好给该配置文件配置权限为044，因为里面存放了加密密码

### BACKUP CONFIGURATION ###

# KEEP THE PASSWORD SAFE. It is HIGHLY recommended to chmod 400 this file so 
# that other users can not read it

# To decrypt backups made by this script, run the following command:
# openssl enc -aes256 -in [encrypted backup] -out decrypted_backup.tgz -pass pass:[backup password] -d -md sha1
#解密命令：openssl enc -aes256 -in 加密文件名.tgz.enc -out decrypted_backup.tgz -pass pass:解密密码 -d -md sha1
