2014-02-14 Backup

This got started on 2006-08-03 Backup using rsync. We’re using several external USB harddisks to keep backups. The most important part is that we have two external disks and we keep at least one of them at Claudia’s office. Just making sure that a simple fire in our flat cannot destroy all our data. I do backups using rsync. Note my Restore page.

rsync

Restore

Look at how the external drives are setup. The Extern disk is always connected and it’s where both I and Claudia keep files such as the iTunes library. That’s why it has the “noowners” flag set. The Backup disk, on the other hand, needs to preserve ownership.

alex@Megabombus:~$ mount
/dev/disk0s2 on / (hfs, local, journaled)
devfs on /dev (devfs, local, nobrowse)
map -hosts on /net (autofs, nosuid, automounted, nobrowse)
map auto_home on /home (autofs, automounted, nobrowse)
/dev/disk2s3 on /Volumes/Backup (hfs, local, nodev, nosuid, journaled)
/dev/disk1s2 on /Volumes/Extern (hfs, local, nodev, nosuid, journaled, noowners)

I run this from my main machine, Megabombus.

#!/bin/bash

    echo you need to mount the backup drive, first
