In the open script, enter:

#! / bin/shmkdir / home/beifen# create a temporary file (the path to save the backup) cp-r / home/backups/balalala / home/beifen# data is stored in the backups directory and backed up to the beifen directory So first copy the data to tar-zcPvf / home/backup$ (date +% Y%m%d). Tar.gz / home/beifen # package the folder where the data resides rm-rf / home/beifen/ # delete the temporary file contents find. /-mtime + 30-name "* .tar.gz"-exec rm-rf {}\ # Delete files under the changed folder for more than 30 days

Type sh / home/beifen.sh again in the terminal and click enter to enable the script
