Amazon EC2 is a VPS, but the instance does not have persistent storage, instead it is always loaded from an image (called AMI), that image is usually stored in S3. I did one snapshot after I finished configuring my server, but that was 4 months ago and I am afraid I (may) not have everything backed up. (Trac repos, mercurial repos, django database records).

After that a '/etc/init.d/apache2 start' just hangs with no error on apache logs. I check system messages and it turns out:* [EMAIL PROTECTED]:/var/log/apache2# tail -f /var/log/messages *Nov 4 23:59:47 pinax kernel: 4gb seg fixup, process bash (pid 23795), cs:ip 73:0016b817 Nov 4 23:59:48 pinax kernel: printk: 2 messages suppressed.
