Linux Data Backup

Today we need to use a backup website, write a script, back up MySQL and redis data.

The next thing to do is to do it regularly.

sudo crontab-e edit cron command, write:

0 6 * * * SH ~/getll_auto_backup.sh >>/var/log/getll/cron.log

Where sudo represents the use of root to execute, then ~ represents the/root directory.

This command means to execute the SH ~/getll_auto_backup.sh command at 6 o ' Day, and redirect the output to/var/log/getll/cron.log, specific to the Google cron command.
