Weekly repeat backup

[deltaboyz]

Hi all,

I have already created a backup scrip that currently is running, however i would like let the task run it repeatedly by overwriting the data for previous week.

Here are the scripts i'm using to run it:

#! /bin/bash
echo Backup Started `date` >> ~/backuplog
mkdir /mnt/usbdrive/backups/`date +%Y%m%d`
tar -czf /mnt/usbdrive/backups/`date +%Y%m%d`/data.tar.gz /data
echo Backup Completed `date` >> ~/backuplog

What are the add in that i need put into so the backup can repeat automatically?

Thanks in advance

You usually would set this up in cron to run this script at set times

Yes, i scheduled it using cron

However, i need to make it will overwrite the data weekly so i don't need to delete those files when the HDD is full.

Is there any command i should add in?

....overwrite the data weekly so i don't need to delete those files when the HDD is full.

1 option: you can use the 'find' command to look for files older than the curent day, I delete my backup files that are older than 6 days, and execute a 'rm' command.

find $backupdir -mtime +6 \( -name "whateveritmaybe" \) -print -exec rm {} \;

A quick look at 'man find' will clear things a bit on that one liner.

You can put that in a script on the weekly cron.
