When you delete any EBS snapshot, if there's a later snapshot for the same volume, every block in the first snapshot that wasn't included in the later snapshot (because it didn't change) is logically rolled forward (in a sense) into the later snapshot, so the later snapshot is still perfectly valid when any or all earlier snapshots are deleted. ...

For me, the main benefit of having multiple smaller EBS volumes rather than one massive one is cost management. As an example right now on our DEV server, we have 3 x 100 GB EBS volumes attached with ZFS (configured in raidz1 but that's because I'm paranoid about data loss). The devs keep telling me that we will need upwards of 1 TB worth of space, but ...

Looks like there is single network link between instance and EBS cloud. The throughput is described here: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSOptimized.html So the answer is, unless IOPS limit is hit, adding more EBS disks won't improve overall EBS performance of the instance.

I have figured out how to solve my problem. The answer by Andrew Lusk pointed me to the right direction. However, my current environment makes me prefer a GUI option versus the command line one. But, he is incorrect in stating that GUI console option doesn't exist for creating a new AMI from an EBS snapshot. I have researched a little bit more and found that ...

It sounds like you want to make a new AMI from an EBS snapshot. The console doesn't let you do this; you should use the command line tools. http://docs.aws.amazon.com/AWSEC2/latest/CommandLineReference/ApiReference-cmd-RegisterImage.html You want 'ec2-register -s snap-XXXXXXXX'.

Think of an EBS volume as just another disk. Once you've created the volume you will need to mount it on your linux instance. To do this from the AWS console, right-click on the EBS volume then choose "Attach Volume". Select the instance you want to attach the volume to, and it should suggest a device name (like /dev/sdg, assuming you're using linux). ...
