Amazon Elastic Block Store (EBS) makes EC2 persistent storage simple, replacing the complex Duplicity and chroot approach described in an earlier post.

Fix Duplicity backup failures caused by too many open files on Linux by raising the file descriptor limit for the backup user in /etc/security/limits.conf.

When Amazon S3 went down it took Web 2.0 sites with it, but sites using Duplicity-backed EC2 kept running — why relying on PersistenceFS is a design flaw.

Use Duplicity, chroot, and Amazon S3 to give EC2 instances persistent storage that survives instance restarts — a detailed 12-step guide with scripts included.

A busy week building an Amazon EC2 AMI with persistent storage that behaves like a physical server — a follow-up post with full details was coming soon.
