Rsync full-network backup enterprise case

There is a Web server in a company, the data is very important, but if the hard disk is spent, the data will be lost, now the leader requires you to make the data on the other servers to do a periodic scheduled backup, the requirements are as follows:

The backup Site Directory is packaged on Web server A every night at 00 o'clock and pushed to Server B by the rsync command (the backup idea can be packaged by date and then pushed to the backup server.) ）

The specific requirements are as follows

1 , the backup directory for Web server A and backup Server B must both be/backup

2 , Web Server Site Directory assumptions (/var/www/html)

3 , the Web server is only locally backed up within 7 days

4 , check that the backup results are normal on the backup server, and send the daily backup results to the Administrator mailbox

5 , 6 of data per week on the backup server is retained, and the other backups are kept for only 180 days backup

Customer Service side

find/backup/$ip-type f-mtime +7-name "*.tar.gz" |xargs rm-fr

CD/&&\

The first command switches to the parent directory

ip= ' Ifconfig eth1|awk-f "[:]+" ' Nr==2{print $4} '

mkdir/backup/$ip-P

  Because we are simulating 50 ip as directory go out of the ip numeric variable is ip create with ip named directory

Tar zcfh/backup/$ip/bak_$ (date +%f_%w). tar.gzvar/www/html app/logs Var/spool/cron/root etc/rc.local

Package The data we want to back up and package it in the previous step to create the IP under directory because you want to delete the backup server the days before the backup data

, in order to differentiate which day the data is backed up, the package name is date+%f date named, the topic also required to retain every Saturday so added %w print out weeks to facilitate later operation

Rsync-av/backup/[email protected]::backup/--password-file=/etc/rsync.password

push the packaged data to the server to make rsync into a password-free mode

find/backup/$ip-type f-name "*$ (date+%f_%w) tar.gz" |xargs md5sum >/backup/$ip/flag_$ (date +%f_%w)

find the data packaged for the day and attach md5sum , at the same time the generated md5sum value is saved to flag_$ (date +%f_%w) compare to the server md5sum value with

find/backup/$ip-type f-mtime +7-name "*.tar.gz" |xargs rm-fr

Because the current directory only uses backup data for seven days, deleting data from seven days ago
