This is a short page detailing backup strategies and tools to use with ec2 instances.
In particular how to use s3sync to synchronise backups with Amazon S3.
maybe obvious ebs cover continously changing data ami cover quite static configuration and data reliable fault tolerant s3 having data locally quick restore of ami after instance death or clustering ebs and use snapshots? not a replacement for proper enterprise backup

plan s3 layout buckets, nameing strategy s3 restrictions plan what to backup, when to backup dont backup ami data at least not often ebs data is also not as volatile dont flood s3 which makes it untity and confusing but also dont miss out on vital data as s3 is relatively cheap so never not backup anything due to s3 cost
if not already part of AMI wget http://s3.amazonaws.com/ServEdge_pub/s3sync/s3sync.tar.gz tar xzf s3sync.tar.gz sudo mv s3sync /opt/ chown -R billy:nomate /opt/s3sync aptitude install ruby sudo vi /etc/profile.d/s3sync PATH=$PATH:/opt/s3sync export PATH
create local accessKeys file as seen on the AMI page Read the s3sync articles play with s3sync s3sync.rb is an overkill, s3cmd.rb put and get should be enough
