View Full Version : [ubuntu] suggested options for using rsync to backup

April 8th, 2009, 08:49 AM
I have a new hdd that I'd like to use to mirror some of my data. I thought I'd go about doing it via rsync and wanted to get suggestions for the community as to the best set of switches to use.

I was thinking about the following after reading through the rsync manpage (http://www.ss64.com/bash/rsync_options.html):

rsync -avux --progress --delete-after /home /media/backups/home

What do you guys think?

the best set of switches
What is "best" for you is not necessarily "best' for me. These switches are "options" after all, allowing you to make choices that suit you nest.

Mirorring a partition requires the options "-a --delete" at minimum. If you want to preserve hard links in the copy, you additionally need the -H switch. This considerably slows down the backup proces, though, which is why that option is not turned on by the -a option by defauult.

I use

rsync -av --progress --delete-after /home/ /media/backups/home

to see if its working.. and

rsync -a --delete-after /home/ /media/backups/home

in my cron scripts to sync between various harddisks. Emphasis on "/home/" to avoid additional folders...

One thing's for sure, you want to start with "-n" which stands for "don't do nothing, just tell me what you would do" ... Believe me, it's 30 seconds well spent...

have fun

If you are going to use rsync a lot to make backups, take a look at Rsnapshot (http://rsnapshot.org/), its an amazing Perl script to use rsync to keep snapshots of parts of your system (or the whole thing)
It is on the repositories.

I used a script to backup with rdiff-backup (It is in the repository), but recently found a new frontend for that: pybackpack.
Very easy.
