[Question] - Backup my system - Debian

[Arquiteto]

Hi all,

 

Let me explain my scenario:

 

+ I''ll build a Debian Home Server based on these tutorials;

+ I want create a task to backup my system (not my personal data, just Debian data) to a flash drive just in case my hdd fail I can recover the system in a blink.

+ I'll have a flash plugged 24h and and a task that will run once a week "mirroring" my OS drive.

 

Does anyone can guide me how to search for this solution? I googled for Debian + backup but found only how to backup personal data, not the OS itself.

 

Thanks!

 

PS1: I'm noob, but can follow any tutorial with no problem.

Might work, not sure if the backup can be tailored to ignore personal files. The first option to create a custom live CD periodically should be close to what you're looking for, allowing you to reinstall the system (in its must recent state) in the event if a failure.

Debian should do that by default using the fallback image, though.

To do the above automatically, you can set up a cronjob to run a shell script once a week. The shell script can contain the commands to initiate a backup (with the right options) using remastersys. Most Linux applications should have a command line interface.

Use Rsync and a cron job.

Interesting, I've visited the page but need to read more.

Looks like a simple solution.

Does this method make a 1:1 copy of my hdd? ex.:  I'll remove the original hdd and place the copy and it will make no difference.

 

Thanks Gentlemen and sorry about my poor English

Rsync is a 1:1 copy, yes. It also does incremental backups, which is useful for large amount of data (only syncs changes, and not everything).

Thanks man!
