#rdsbackup

######Use rdsbackup to copy your RDS snapshots to another AWS region for backup/DR purposes.

####Example: rdsbackup --source=us-east-1 --dest=us-west-1 db_name

####Usage:

  rdsbackup [options] <db_instance_id>
  rdsbackup -h --help
  rdsbackup --version

AWS Authentication:
  Either use the -K and -S flags, or
  set the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables.

Options:
  -s, --source=<region>     AWS region of source RDS instance [default: us-east-1].
  -d, --dest=<region>       AWS region to store backup RDS snapshot [default: us-west-1].
  -p, --purge=<count>       Purge oldest snapshots from dest region if more than <count> exist.
  -q, --quiet               Silence all output except errors.
  -h, --help                Show this screen.
  --version                 Show version.

####Purging old snapshots: AWS imposes a limit of 50 RDS snapshots per region. Use the --purge flag to purge an instance's oldest snapshots from the destination region. rdsbackup will never purge snapshots from the source region.

rdsbackup tags all snapshots it creates as follows. It will only purge snapshots in the destination region that that have a "managedby" tag set to "rdsbackup".

tag	value
managedby	rdsbackup
source	<SourceRegion>
sourceid	<SourceDBIdentifier>
sourcearn	<SourceDBARN>
time	<2006-01-02 15:04:05 -0700>
timestamp	<SecondsSinceEpoch>
