call bgsave and sleep 5 loop until lastsave changes upload backup rdb to S3

redis_save.sh

#!/bin/bash

rediscli=`which redis-cli`
s3cmd=`which s3cmd`

lsave=`$rediscli lastsave`
echo "LASTSAVE $lsave"
saved="`$rediscli config get dir | xargs | cut -d ' ' -f 2`/`$rediscli config get dbfilename | xargs | cut -d ' ' -f 2`"
$rediscli bgsave
while [ $lsave -eq `$rediscli lastsave` ]; do
  sleep 5
done
echo "LASTSAVE `$rediscli lastsave`"
echo "BGSAVE complete! ($saved)"

s3bucket="${1:-<YOURBUCKET>}"
s3filepath="${2:-/backups/redis/backup.rdb}"
$s3cmd put $saved s3://$s3bucket/$s3filepath
