Note that if you are using the Express version, you can't have more than like a 4GB database anyways (+ limitations on processors, memory allowed to be allocated, etc). Also, since the EBS is not guaranteed to not have a single point of failure, in the unlikely event that this does fail, you may not have access to the backup EBS either. If anyone has ideas about circumventing these limitations, feel free to let me know. The downside of this is that the S3 supports a maximum of 5GB files (at this moment) and snapshots.

Goldberg said: “NEVER, add to the Volume more backups. You are just in danger of mucking up all of the backups on that volume.” I don’t undertand why… Snapshot EBS are “magic incremental”, smaller than a snapshot from a new volume and backups remain independent from each other Any ideas ?

I had to do a couple of things: 1) Change Ionic.Utils.Zip -> Ionic.Zip (as Neil pointed out) 2) Change sqlcmd -Q $query -S "." > sqlcmd -Q $query -S localhost\SQLEXPRESS (presumably because of using SQL Express?) Thanks again, Dominic Brilliant stuff thanks. I had to do a couple of things:

Thanks a lot! You said that : "While i haven’t had an instance die from under me, if one should cop it, all data on the local disks will be gone-gone." Can you give me idea of having any of your instances died so far.If they did after how long life they died?I am curious and a bit tensed to know how reliable an instance is?

I am a developer and not a DBA but for back instead of doing log shipping and storing transaction logs I am thinking to have a differnt solution which can work like Full backup.I think to have 5 snapshots of my EBS database through out the day.Snapshots older than 2 days will be deleted.In this case all snapshot will have Fullbackup for last 2 days as those are going to be exact same copy of EBS volume. Is this going to work or its too much allocation of S3? Waitig for your suggestions.
