Replacing Vmware with Virtualbox

February 1, 2008 Leave a comment

It’s still a Windows world. There’s no way to escape it. While I, for the most part, love running Linux rather than Windows on my laptop, there are still many things that I need Windows for. For one thing, I often need to see what things look like on IE, and there are still some programs that require IE to run (some people are still stuck in the 20th century).

I’ve been running Vmware, which lets me run Windows in a virtual machine under Linux,  for a few years and have been mostly happy with it. I recently made the mistake though of clicking on the “there’s a new version available” that’s been nagging in the program for a while. I installed the latest version of Vmware only to be informed that I don’t have a license for the most recent version. Sneaky. Fine. So I looked around and sure enough, there’s now a free program, Virtualboxk, that does the same thing that Vmware does.

I downloaded and installed it,. It worked out of the box, but then for some reason I couldn’t get it to go back and forth using NAT between my network card and my wireless card. I  played around with the networking a bit more and now it works like a charm.  Great program, feels more solid and faster than Vmware. I happily send 30 Euros to the company.

Backup using duplicity to S3

January 29, 2008 Leave a comment

Most of what’s needed to backup a linux box to S3 is covered in

http://www.brainonfire.net/2007/08/11/remote-encrypted-backup-duplicity-amazon-s3/

The good news:

  • Simple setup (see below)
  • Cheap backup
  • Encrypted backup. Even if someone manages to get to your data on s3, they still won’t be able to do anything with it.

Worked like a charm on my laptop, but I had many issues on my home server.

It took me quite a while to realize that the version of duplicity I had on ubuntu feisty doesn’t support s3 backup and I need to download the product from http://duplicity.nongnu.org/ rather than use the package.

The second issue is that I did the initial backup of the laptop at work where we have multiple T3s. At home I have a connection that’s 3M download 512K upload. That translates to 200M/hour 5Gig/Day backup, which means that the initial backup is going to be slow, and will slow down your connection to a crawl.

Also, duplicity doesn’t support a resume feature. So if your backup fails at some point, next time you run the script it’ll start from scratch and backup everything.

  #your pgp secret to encrypt your data
export PASSPHRASE=xxxxxxxxx

#S3 info
export AWS_ACCESS_KEY_ID=xxxxxxxxxxxxxxxxxxxx
export AWS_SECRET_ACCESS_KEY=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

echo "backing up /etc"
duplicity /etc s3+http://drormata-e1705-etc

#Notice how you can exclude certain things
echo "backing up /home"
duplicity ---exclude=/home/dror/.mozilla/firefox/54y9nzlg.default/Cache --exclude=/home/dror/tmp --exclude=/home/dror/.opera --exclude=/home/dror/.thumbnails --exclude=/home/dror/download --exclu
