I have some 8 instances in Amazon. Could someone tell me how I can create a backup/image of a running instance?
I have already gone through their database. But I could not understand it. Someone please help me.
Yes just need to take snapshots, Goto EC2,
Select volumes. Select the volume you want to take backup and then take snapshot.
You may export them to s3 even, if needed
Hope it helps.

We have one Linux and one Windows VM that we no longer have a need for. Before we delete the VM, we would like to back it in case we need to go back to it. What is the best way to do this?
Thank you!

The best method is to use the Azure Backup Service

Long story short, I was mounting a disk to my vm instances but I didn't specify the NOFAIL_OPTION on /etc/fstab. Thus, after resarting the instance, i could not access the ssh. After trying to access the serial console, I got the error in the image above. I have tried to search some answer and have add startup script to add sudo user
However, it didn't solve my problem. Basically,I need the data on the boot and additional persistent disk. Would appreciate any help. Thank you.
I solve the problem by making changes to the file by attaching the bootable disk as additional disk on new instance just like John said in his article
:) Thanks! hope this will be helpful for those who could not access ssh and need to make changes to the unbootable system file.
This also happened to me recently. I solved the issue by attaching the boot disk of the problematic instance to a new instance, however, the NO_FAIL causing the system to break is what interests me. This has never happened before. The UUID is correct, and the syntax is also correct, hence what was the cause of the original problem in your case? I'm still trying to figure mine out.
I've poured over the Amazon RDS documentation but I can't seem to find an answer to this simple question. Has anyone tried it?
The answer, at least at the time of this post, appears to be no. The Modify Snapshot option is grayed out for Aurora snapshots, and when I try to restore one, the DB Engine is set to aurora-postgresql and cannot be changed.
I was working on my azure VM today (BASIC, A1 (1core, 1.75GB memory)), after i was prompted to restart the VM for windows updates. it was down for an full hour. When i was able to connect back to it. this message appeard:
Since i dont have 10 reputation, this is the link to the error my VM gives me.

At this point. i cant do anything to the VM because of the risk of losing data. But i also dont know if this ever goes away (its already 2 hour like this.)
If anyone could inform me on whats going on or want to help me. Help is much apreciated
The answer was found, There was a problem at the update service right at the moment i was going to update the VM. After a few tweets i managed to fix it with them.
I was wondering if I could use a shell script on a remote server to create an amazon EC2 instance from an existing saved snapshot, and also delete that instance too.
I was sure it was possible, but I havent been able to run any example code to do it so im starting to doubt it now.
So, can anyone tell me how this is done please?
There is a quite detailed description on the Amazon webpage how to do this:

At which point are you struggling?
