comment Snapshots == EBS backed instance, persistence, and S3 storage?
Volumes are hard disks that you can plug into any instance you like, either as the root or as any other drive. An image is an AMI. It's what you use to spin up new instances, based on the disk image stored in the snapshot.

comment Any other Linux application similar to Greyhole?
Atleast conceptually, it looks like Greyhole is just a simplified interface to mdadm and samba. What experience do you have with Linux? Setting up either of these is not particularly difficult, with a bit of research.

comment Amazon EC2 Backup Strategy With Restrictions (little to no snapshots can be taken?)
@BartSilverstrim: The other big advantage is near zero downtime in the case of a castrophic problem (intrusion/accident/whatever). You can just stop the instance, mount a new root EBS volume from a snapshot and start up again. 5 minutes turn around tops. And you still have a pristine version of the problem volume for examination to find out what went wrong.

@Bart: I'd also suggest that snapshots are as 'hot' a backup as you are going to get, and also far more internally consistent than rsync or similar. Files can change while others are transferring, meaning you may end up with a useless backup in some situations. I'd personally recommend that you eat the few hours downtime to change filesystems (if required) to make snapshots work. It's amazing how flexible a backup solution the EBS snapshots are, you can mount them on your running instance to restore.

@Bart: If you're willing to endure an hour or two downtime, it's possible to migrate an existing snapshot to XFS. I also believe that ext4 does now support the required stuff to make consistent-snapshot work, if you are on that filesystem instead.

@MDMarra: Then close the old question. Rewriting the entire question isn't productive either. The issue is nothing to do with Samba, and everything to do with the hardware.

comment How to identify which hdd to be replaced in RAID
@Radek: RAID5 has redundancy for one disk. It should keep going with just a single disk broken.

comment Unreasonably slow stunnel
@KitSunde In a live environment, it's not uncommon to have Django/Rails/etc servers running against localhost and have them reverse proxied by a 'real' HTTP server like apache or nginx. Is that viable? Nginx is pretty darn slim, but I don't know what sort of specs your dev machine has.

Any reason you didn't just set up your HTTP server to serve HTTPS as well? Seems that'd be the simplest way to me.
