I am looking at backup options within AWS and while instance snapshots are the obvious way to go I am have some concerns about using that method.
I'd like to take daily snapshots of each instance without stopping the instance (as they are production instances) however if I do this I am concerned that a file may be in the process of changing in some way or haven't been written to disk as yet. I am concerned that the files stored in the snapshot would possibly be corrupt due to this.
Of all my instances are EBS backed and are running linux, are my concerns valid and should I be looking at another way to back up in AWS?
Thanks!
