• Archiving a large backup across multiple discs on Linux

     

    Hopefully, we all back up our data, but what should we do once our data won't fit on our chosen media?

     

    We have two options (as we obviously don't want to delete our data!)

    • Use a different backup medium
    • Split the backup across multiple volumes

    Sometimes the former just isn't appropriate, as much because of the cost of harddrives vs Optical Media (i.e. CD's/DVD's).

    This short tutorial will explain how to create a single backup archive, and then split it across multiple CD's/DVD's.

     

  • Implementing Encrypted Incremental Backups with S3cmd

    I've previously detailed howto use S3cmd to backup your data from a Linux machine. Unfortunately, because of the way that s3cmd works, if you want an incremental backup (i.e. using 'sync') you cannot use the built in encryption.

    In this documentation I'll be detailing a simple way to implement an encrypted incremental backup using s3cmd, as well as a workaround if you're unable to install GPG - instead using OpenSSL to encrypt the data. Obviously we'll also be exploring how to decrypt the data when the backups are required

    It's assumed that you've already got s3cmd installed and configured to access your S3 account (see my earlier documentation if not

  • Syncing your files with an S3 account on Linux

    Amazon's cloud is incredibly useful for a number of things, including backup. I don't, as a rule, trust much to 'the cloud' but it does provide a nice easy way to achieve off-site backups at a reasonable cost.

    This documentation explains one of the many ways to achieve automated backup to your S3 account (set one up here).
