This is a quick and dirty EC2 backup script for virtual unix servers that works just fine when crontabbed:
#!/bin/bash
DATE=`date +%m%d%Y-%H%m%M`
BUCKET=”codebelay-$DATE”
PRIVATE_KEY=’pk-codebelay.pem’
PRIVATE_CERT=’cert-codebelay.pem’
USERID=’555555555555′
AWS_ACCESS_ID=’AKIA0000000000000′
AWS_SECRET=’asdf+asdf+asdf+asdf’
s3cmd mb s3://$BUCKET
cd /mnt
mkdir img
ec2-bundle-vol -d /mnt/img -k /mnt/$PRIVATE_KEY -c /mnt/$PRIVATE_CERT -u $USERID -s 9999 –arch i386
cd /dev
mkdir loop
cd loop
mknod 0 b 7 0
ec2-upload-bundle -b $BUCKET -m /mnt/img/image.manifest.xml -a $AWS_ACCESS_ID -s $AWS_SECRET
# rm -rf /mnt/img
echo “please register $BUCKET/image.manifest.xml” >> /mnt/registerbackups.txt
