In linux, the backup is automatically packaged and deleted five days ago.

Project requirements

1. Automatically package a file directory,

2. The package file is automatically placed in a specified directory.

3. The files generated five days ago are automatically cleared;

Implementation:

1. Use crontab for Scheduled Backup

2. Use tar for compression

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

4. Add the backup file baksvn to the/usr/sbin directory.

#! /Bin/sh
Rq = 'date + % Y % m % d'
Rm-f/home/svnbak/'date-d'-5 days 'using policyuncm=d'.tar.gz
Tar zcvf/home/svnbak/$rq.tar.gz/var/svn/document

Likewise, mysql backup can be implemented.

You only need to add

Mysqldump-uroot-p XXXXXX>/home/XXXXXXx_bak_20150108.dat

As follows:

#! /Bin/sh
Rq = 'date + % Y % m % d'

Mysqldump-uroot-p XXXXXX>/home/XXXXXXx_bak _ $ rq. dat
Rm-f/home/svnbak/'date-d'-5 days 'using policyuncm=d'.tar.gz
Tar zcvf/home/svnbak/$rq.tar.gz/var/svn/document
