Automatically pack backups and delete files 5 days ago under Linux

Project requirements

1. Automatically package a file directory,

2. Automatically place the packaged files in a specified directory

3. Automatic removal of documents 5 days ago;

Realize:

1. Use Crontab for scheduled backups

2. Using tar compression

3. Use the shell to calculate the date, remove the old file

4. Add backup files to the/usr/sbin directory: BAKSVN

#!/bin/sh
rq= ' Date +%y%m%d '
Rm-f/home/svnbak/' date-d '-5 days ' +%y%m%d '. tar.gz
Tar zcvf/home/svnbak/$rq. tar.gz/var/svn/document

Similarly, a backup of MySQL can be implemented.

Just add it before compression

Mysqldump-uroot-p XXXXXX >/home/xxxxxxx_bak_20150108.dat

As shown below:

#!/bin/sh
rq= ' Date +%y%m%d '

Mysqldump-uroot-p XXXXXX >/home/xxxxxxx_bak_$rq.dat
Rm-f/home/svnbak/' date-d '-5 days ' +%y%m%d '. tar.gz
Tar zcvf/home/svnbak/$rq. tar.gz/var/svn/document
